Move Away From The Press Review

Well, a little bit of history about the press revue. Initially, the press review was born as a request from one of my customer, a little more than four years ago. A this time, this revue was oriented towards its locally used technology only, and was commented and discussed to sum things up appropriately according to its own needs.

Since then, this revue was finally regularly published on this blog--some months after I leaved this customer in fact--, but it now takes me some time to collect and format, and was not really discussed anymore: it's just a bunch of (I hope ;-)) interesting links, but without much of value as it stands now. More, that information which are asynchronous by nature are not well served when published once a month, when interesting news came at the beginning of a month and is only released four weeks later through the press revue.

So, I decided to push these links more synchronously through my Twitter account, which feed this need more appropriately I think. This way the information will flow more regularly, and no need to wait for a bunch of them late each month. Please Follow @_thnet to subscribe to the new form of the press review :)

Last, I just want to say I will try my best to resurrect the old purpose of this blog which is more about writing technical contents, better served using this kind of media.

I hope these changes will fit your needs. Please let me know if you see any problem with this move. Thank you.

Press Review #27

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

How to Use Hardware Fault Management in Oracle Linux

Understanding, installing, enabling, and using IPMI and MCE—two hardware fault management tools in Oracle Linux.

Preparing for #OOW: DB12c, M6, In-memory, Clouds, Big Data... and IoT

It’s always difficult to fit the upcoming Oracle Open World topics, and all its sessions in one title, even if "Simplifying IT. Enabling Business Transformation." makes it clear on what Oracle is focusing on, I wanted to be more specific on the "How". At least for those of you who attended Hot Chips conference, some of the acronyms will be familiar to you, some may not (I will come back to "IoT" later). For those of you attending, or those of you who will get the sessions presentations once available online, here are few things that you don't want to miss which will give you not only what Oracle R&D has done for you since last year, but also what customers -like you- have implemented thanks to the red-stack and its partners, being ISVs or SIs.

Misys Kondor+ runs best on SPARC T5

Misys is a leading financial software vendor, providing the broadest portfolio of banking, treasury, trading and risk solutions available on the market. At ISV Engineering, we have a long-standing collaboration with the Kondor+ product line, that came from the Turaz acquisition (formerly part of Thomson Reuters) and now part of the Misys Treasury & Capital Markets (TCM) portfolio. Jean-Marc Jacquot, Senior Technical Consultant at Misys TCM, was recently interviewed by ITplace.TV (in French language) about a recent IT redesign of the Kondor+ installed base at a major French financial institution.

FAQ2: Analyzing Large Volumes of nmon Data

I regularly get asked a question like: I have 4 months of data from 25 machines and have to develop a Capacity Planning model to size these LPARs on to new machines but I am having problems with having so much data. What can you recommend?

FAQ3: How can I Monitoring Shared Processor Pools longer term?

[...] The CPU Pool information is gathered (if switched on) at the HMC via the service processor but extracting it and then using it to generate graphs or spreadsheet data is extremely complex particularly if you have a complex set of up to 64 CPU Pools!

Happy 10th Birthday, DTrace!

Ten years ago this morning — at 10:27a local time, to be exact — DTrace was integrated. On the occasion of DTrace’s fifth birthday a half-decade ago, I reflected on much of the drama of the final DTrace splashdown, but much has happend in the DTrace community in the last five years; some highlights...

You won't find this in your phone: A 4GHz 12-core Power8 for badass boxes

Hot Chips Big iron sales are still generating $6bn to $7bn a year for IBM - which is enough to justify designing its own Power processors and building its own wafer baker.

At the Hot Chips conference at Stanford University on Monday, some of the chief architects behind the Power8 electronics were on hand to show off the feeds and speeds of the next-generation motor for the company's Power Systems lineup.

Advanced Network Monitoring Using Oracle Solaris 11 Tools


In this article, we will examine three use cases in order to demonstrate the capability of Oracle Solaris 11 tools. The first use case will show how to measure the network bandwidth between two systems. The second use case will demonstrate how to observe network statistics on a specific TCP port, and the last use case will demonstrate, by example, how to collect and display historical statistics of network resource usage for a given date and time range.

Announcing: ZS3 - Oracle's Next Generation Application Engineered Storage


On 10th of September, Oracle announced its latest ZFS Storage Appliances, the ZS3 Series, that enables customers to accelerate time to insight, while extensive Oracle co-engineering improves operational efficiencies and reduces data center costs through dynamic automation through the Oracle stack. As IT skills converge, the ZS3 provides enterprises with the ability to respond to application needs dynamically while reducing time-to-business benefits.

Solaris 10 Patches Now On Monthly Release Cadence

We've recently moved to a monthly release cadence for Solaris 10 OS patches.

New Solaris 10 OS patches are now available from MOS by the Monday closest to 17th of each month.

Solaris Random Number Generation

  • https://blogs.oracle.com/darren/entry/solaris_random_number_generation

    The following was originally written to assist some of our new hires in learning about how our random number generators work and also to provide context for some questions that were asked as part of the ongoing (at the time of writing) FIPS 140-2 evaluation of the Solaris 11 Cryptographic Framework.

How to determine why your AIX oslevel is downlevel (and a script to help!)

To determine the oslevel on AIX, you can run the "oslevel -s" command.   However, what "oslevel -s" reports doesn't always show the entire picture.   The OS level reported will be the lowest level of any installed AIX fileset on your server.

Amazon, Avere and Oracle Offer Up the Most Transformational Technologies at VMworld 2013

The good news is that what Oracle had to share with me about its innovations in storage went well beyond anything I could have possibly imagined and it was certainly better than anything I was hearing on the VMworld show floor. In short, what Oracle has done has brought together the best of what ZFS has to offer and tied that together with the best of what of its Oracle databases have to offer to deliver Oracle application performance that far outshines what anyone else can even remotely hope to offer anytime in the near future.

Top Tips for Updating Solaris 11 Systems

We now have quite a bit of experience of IPS and Repositories under our belt.

Feedback from customers has been extremely positive.  I recently met a customer with 1000+ Solaris servers who told me that with Solaris 10 it took them 2 months to roll out a new patchset across their enterprise.  With Solaris 11, it takes 10 days.  That really helps lower TCO.

Oracle VM virtualization on T4-4 : architecture and service catalog

Last Tuesday, during the SPARC Showcase event, Jean-François Charpentier, François Napoleoni and Sébastien Flourac delivered very interesting uses cases of deployment of latest Oracle Systems at work : Oracle VM virtualization project on T4-4, intensive financial trading on T5-2 and a complete Information System migration to Oracle SuperCluster.

GRTgaz new Information System on Oracle SuperCluster

This testimony from Mr Sébastien Flourac, Head of Strategy for GRTgaz IT, concluded the last week SPARC Showcase event. Mr Flourac highlighted why he selected an Oracle SuperCluster, Engineered Systems, over a more traditional build it yourself approach, that he also studied.

#OOW2013: All your Database in-memory for All your existing applications... on Big Memory Machines

Many announcements have been made today by Larry Ellison, during his opening of Oracle OpenWorld.  [...] On OpenWorld side, it was also very impressive. More people this year are attending the event : 60 000 ! And in terms of big numbers, we saw very impressive results of the new features and products that have been announced today by Larry: Database 12c in-memory option, M6-32 Big Memory Machine, M6-32 SuperCluster and Oracle Database Backup, Logging, Recovery Appliance (yes, I am not joking, that's its real product name !).

PureSystems Anyone?

IBM introduced the PureSystems in April 2012. It was a big deal and it still is. IBM is certain this is the system to converge all systems, with infrastructure in a box--PureFlex--as the solution to the huge business knot caused by IT redundancies. Instead of each platform requiring its own infrastructure, this is one infrastructure for all and all for one. In the past year and a half, the successes have mostly piled up on the X86 side as a server consolidation play, but IBM i shops are in this game, too.

Oracle's SPARC M6

Companies are awash in data. In fact, Science Daily reported that 90% of the world's data was generated over the last two years. Capturing, integrating, and analyzing massive amounts of data from both social media interactions and traditional in-house systems demands a shift to in-memory processing.

With Oracle's new SPARC M6-32 systems, customers can now run entire applications in memory. Based on the SPARC M6 12-core processor, these systems have a staggering 32 terabytes of system memory and up to 384 processor cores with 8-threads per core. The SPARC M6-32 provides twice the memory capacity of IBM Power servers and delivers extreme in-memory compute performance for large-scale, mission-critical workloads and databases. And it offers the highest levels of system availability for core business applications.

Alternative flash architectural implementation options for AIX with detailed instructions on implementing LVM mirroring with preferred read from flash

This document discusses the benefits and positioning of using AIX LVM mirroring with preferred read from Flash/SSD and provides detailed implementation steps to set it up.

Solaris General Session at Oracle Open World 2013

[...]
Here are some of the highlights of what's coming in the next release:

kernel zones: With kernel zones customers will have to option to run different kernel patch levels across different zones while maintaining the simplicity of zones management. We'll also be able to do live migration of kernel zones. All of that across HW platforms, i.e. kernel zones will be available on both SPARC as well as x86. Key benefits of kernel zones:

  1. Low overhead (Lots of optimizations because we run Solaris on Solaris)
  2. Unique security features: Ability to make them immutable by locking down the root file system
  3. Integration with the Solaris resource management capabilities: CPU, memory, I/O, networking
  4. Fully compatible with OVM SPARC as well as native and S10 branded zones
  5. Comprehensive SDN capabilities: Distributed Virtual Switch and VxLAN capabilities

[...]

Press Review #26

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

READ_ME_FIRST: What Do I Do With All of Those SPARC Threads?

With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources.

In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading.

Linux Container (LXC) — Part 2: Working With Containers

Part 1 of this article series provided an overview about the Linux container technology. This second part intends to give you an impression on how to work with containers, by showing a few practical examples. These can be easily followed and reproduced on an up to date Oracle Linux 6 system. For the first steps, it is recommended to install Oracl Linux inside a virtual environment like Oracle VM VirtualBox. Oracle provides a pre-installed and pre-configured Oracle Linux 6 Virtualbox image for free download from the Oracle Technology Network (OTN).

How to Get Best Performance From the Oracle ZFS Storage Appliance

These articles (a seven-part series) provides best practices and recommendations for configuring VMware vSphere 5.x with Oracle ZFS Storage Appliance to reach optimal I/O performance and throughput. The best practices and recommendations highlight configuration and tuning options for Fibre Channel, NFS, and iSCSI protocols.

The series also includes recommendations for the correct design of network infrastructure for VMware cluster and multi-pool configurations, as well as the recommended data layout for virtual machines. In addition, the series demonstrates the use of VMware linked clone technology with Oracle ZFS Storage Appliance.

IBM upgrades Flex Systems line

IBM on Tuesday rolled out a series of new Flex Systems that are designed to pack more computing power in tight data centers for cloud services.

IBM Opens POWER Technology for Development

IBM, along with Google, Mellanox, NVIDIA and Tyan, has announced that it will form a new consortium called OpenPOWER. The OpenPOWER Consortium will leverage IBM’s proven POWER processor to provide an open and flexible development platform aimed at accelerating the rate of innovation for advanced, next-generation data centers.

Back in time - or: zpool import -T

Sometimes you find out interesting stuff just by Google and trying something out. Yesterday i've searched for some information for ZFS on FreeBSD (one the OSes i keep in my OS zoo) and in the course of it, i found a mail on a FreeBSD list talking about the command zpool import -T . -T? There is no -T option on zpool import? Or is it just in FreeBSD?

MISYS, Kondor et les Sparc T5 sécurisent les transactions bancaires

Misys est un éditeur majeur dans l’édition de progiciels bancaires, notamment autour des solutions de trading et de risk management. Nous représentons plus de 60% de ce marché dans le monde. Nous sommes présents dans les 4 banques institutionnelles françaises. [...]

Nous menons actuellement une mission de refonte d’architecture chez un grand client bancaire que nous ne citerons pas. L’existant, c’est un parc hétéroclite de serveurs SPARC/Solaris sur lesquels tourne l’application KONDOR.

mirroring progress in AIX

In the past, I posted this "snippet" as the solution to often asked question – how much mirroring is done? Today, I had an opportunity to use it. Man, it works like charm!!! Such a small thing but so much joy :-) Oh boy, I am overdoing it for sure...

Flash geometry and performance

Last year StorageMojo interviewed Violin Memory CEO Don Basile. He noted that as flash features sizes shrank, NAND would get slower as well as reducing endurance.

IBM Forms OpenPower Consortium, Breathes New Life Into Power

Back in July, I started what will eventually be a series of stories on what IBM should be doing with its systems business. And like a bolt from the blue, the company did something that I have been mulling for the past several months in earnest and noodling for the past several years off and on. And what IBM has done is to mimic the ARM collective and open up the intellectual property surrounding its Power chips to help foster a broader ecosystem of users and system makers.

IBM To FTC: Make Oracle Stop Running Those Mean Server Ads Please

Oracle is back in lukewarm water over a line of ads that say its own Sparc and Exadata servers are between two and 20 times better than IBM's Power Systems servers. This time, instead of getting another slap on the wrist from an independent industry board that oversees advertising in the U.S, it could get a slap on the wrist from the Federal Trade Commission itself. It's time for IBM, which called Oracle "a serial offender," to take matters into its own hands.

Exploring Installation Options and User Roles

Part 1 of a two-part series that describes how I installed Oracle Solaris 11 and explored its new packaging system and the way it handles roles, networking, and services. This article focuses first on exploring Oracle Solaris 11 without the need to install it, and then actually installing it on your system.

The life of a Linux RPM (package)

Another frequently asked question related to Oracle Linux is how versions of specific packages (RPMs) are picked.

Re-installing the IBM PureFlex™ System and IBM Flex FSM

So you have broken the FSM in you IBM Flex or IBM PureFlex™ System, either it won't power on any more, or its just failing to start. In my case after a software update it wouldn't boot up correctly and some how the root user had been corrupted, so this meant that I couldn't get access to the system. Below I'll go through the steps I took to get the software re-installed from the 'recovery' section of the internal disk on the FSM node.

Setting up a InifniBand Network on IBM POWER AIX

In this doc I'm going to cover the considerations and set-up of a infniband network, so you will need to pre plan the number of systems that you need and the bandwitch of the adpater you plan to use.

ZFS/SLOG on SAN

What if you have ZFS deployed on SAN in a clustered environment and you require a dedicated SLOG?

It was never easier than today - Upgrading/Patching Solaris Cluster 4 and Solaris 11

  1. step: "scsinstall -u update" on all cluster nodes, while the system is running
  2. step: "init 6" one node by one to perform a rolling upgrade.

That looks easy, doesn't it?

Less known Solaris 11.1 features: pfedit

It's a really nifty feature: Let's assume, you have a config file in your system and you want to allow your junior fellow admin to edit it from time to time, but don't want him to pass any further rights to him, because this machine is too important.

Solaris 11.1 has an interesting feature to delegate the privilege to edit just a file. The tool enabling this is called pfedit.

Memory Leak (and Growth) Flame Graphs

Your application memory usage is steadily growing, and you are racing against time to fix it. This could either be memory growth due to a misconfig, or a memory leak due to a software bug. For some applications, performance can begin to degrade as garbage collection works harder, consuming CPU. If an application grows too large, performance can drop off a cliff due to paging (swapping), or the application may be killed by the system (OOM killer). You want to take a quick look before either occurs, in case it’s an easy fix. But how?

Less known Solaris 11.1 features: Auditing pfedit usage

You have allowed junior to edit the httpd.conf and and some nice evening, you are sitting at home. Then: You get alerts on your mobile: Webserver down. You log into the server. You check the httpd.conf. You see an error. You correct it. You look into the change log. Nothing. You ask your colleagues, who made this change. Nobody. Dang. As always. Classic "Whodunit".

segkp revisited

When you are runing quite a number of zones and running applications with a lot of threads and your system sends you messages like "cannot fork: Resource temporarily unavailable" in all your zones in parallel and you are not running Solaris 11.1, you should do the following checks. The following checks are for a system without any changes in this regard of segkp in the /etc/system. The numbers used in this example are obfuscated by rounding from a real-life example.

Oracle Sun System Analysis (les bonnes pratiques MOS)

Oracle VM Server for SPARC 3.1

A new release of Oracle VM Server for SPARC has been released with performance improvements and enhanced operational flexibility.

Upgrading to Oracle VM Server for SPARC 3.1 using Solaris 11.1

The previous blog entry described new features in Oracle VM Server for SPARC 3.1, and I commented that it was "really easy" to upgrade. In this blog I'll show the actual steps used to do the upgrade.

HOWTO Interpret, Understand and Resolve Common pkg(1M) Errors on Solaris 11

Solaris 11 has been out on the market for nigh on two years and it's an absolutely brilliant evolution in the history of Solaris, however I've come to notice one common issue that really shouldn't be an issue at all: the number of calls we're getting from people not being able to interpret the failure messages that pkg(1M) produces.

This post aims to explain how to interpret, understand and resolve the most common pkg(1M) errors.

SPARC presentations at Hotchips 25

I think we will see some news in the usual news outlets about upcoming SPARC silicon soon. The agenda of the currently running Hotchips 25 conference has three presentations related to SPARC...

Less known Solaris 11.1 features: A user in 1024 groups and a workaround for a 25 year old problem

For a long time the maximum number of groups a user could belong to was 16, albeit there was a way to get 32. In Solaris 11 and recent versions of Solaris 10, the maximum number of groups a user could belong to is 1024 (which is the same limit Windows sets in this regard). It's easy to set the new limit.

Oracle Virtual Compute Appliance

There has been major news on the Oracle virtualization front with the announcement of the Oracle Virtual Compute Appliance ("OVCA" for short). This is an Oracle engineered system designed for virtualization, joining Oracle's family of engineered systems such as Exadata, Exalogic, and Oracle SuperCluster T5-8.

OVCA is is intended for general purpose use for a wide range of applications in virtual machines rather than being optimized for a specific workload. It is especially designed for quick deployment into production and ease of use. Customers can start up virtual machines about an hour after OVCA installation. That provides faster "time to value" than taking general purpose systems and designing, adding, and configuring the network, storage and VM software needed to be useful.

An important milestone

Yesterday, with very little fanfare, illumos passed an important milestone.

So, what makes Solaris Zones so cool?

How do you virtualize? Do you emulate virtual machines? Do you partition your servers' hardware? Or do you run a container technology?

This post is about the third option, a container technology built right into Solaris: Solaris Zones. They are pretty awesome, especially on Solaris 11 - they're like vacation: once you go Zones, you won't want to leave them :) But what exactly makes Zones so cool?

Less^H^H^H^HUnknown features of Solaris 11: Virtual Consoles

Next time you are working on the console of your system (perhaps just the console you see in Virtualbox), just try pressing the alt-Key and the cursor left or cursor right key in parallel respectively Alt+F1 for the first, the system console. Alt+F2 for the second console ... and so on. Nothing innovative, especially as Solaris used to have them in the past (but lost them out of reasons unknown to me) ... more a feature from the "Damned! At last!"-department, but still really useful.

WP: SPARC M5 Domaining Best Practices Whitepaper

To learn more about "Domaining" take a look at the recent (August 20th) announced whitepaper: SPARC M5-32 Domaining Best Practices.

The SPARC M5-32 server provides three distinct forms of virtualization:

  1. Dynamic Domains
  2. Oracle VM Server for SPARC
  3. Oracle Solaris Zones

Oracle revs up Sparc M6 chip for seriously big iron

Bixby interconnect scales to 96 sockets

Hot Chips The new Sparc M6 processor, unveiled at the Hot Chips conference at Stanford University this week, makes a bold statement about Oracle's intent to invest in very serious big iron and go after Big Blue in a big way.

Oracle's move is something that the systems market desperately needs, particularly for customers where large main memory is absolutely necessary. And – good news for Ellison & CO. – with every passing day, big memory computing is getting to be more and more important, just like in the glory days of the RISC/Unix business.

Oracle software will run faster with new SPARC M6 chip

Oracle's database and high-performance workloads will run faster with the company's latest SPARC M6 chip, which has been tuned specially for the company's applications.

The latest SPARC processor has 12 processor cores, effectively doubling the number of cores than its predecessor, M5, which shipped earlier this year. Each M6 core will be able to run 8 threads simultaneously, giving the chip the ability to run 96 threads simultaneously, said Ali Vahidsafa , senior hardware engineer at Oracle, during a presentation about M6 at the Hot Chips conference in Stanford, California.

Press Review #24

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

Using ndisk64 to test new disk set-ups like Flash Systems

This is a typical request from IBMers in services or direct from customers wanting to confirm a good disk setup or confirm disks deliver as promised. This time "... a test of SAN disk performance where LUN's are carved from a IBM Flash System 820 with SVC. Primary objective is to show the IBM Flash System 820 can do hundreds of thousands IOPS with response time <1ms with good throughput. This is for an Oracle RDBMS using ASM".

A SPARC CPU Overview: SPARC64-VII+ (M3), T3, T4, T5, M5, M10 - how do they compare?

Do you know how many SPARC CPU types does Oracle deliver currently? Not one, not two, but five. The SPARC64-VII+, the T4, T5, M5 and M10.

Instant Automated Installer Zone for Oracle Solaris 11.1

We've just introduced something new to make it easier to start working with AI, so you can get past that "different" part and start reaping the (major) benefits. The name's kinda long: Oracle Solaris Zone with Automated Installer and Repository... but that's because there's a lot it's doing for you in one shot. As the name implies, it sets up a new zone on your system, with a local Oracle Solaris 11.1 package repository for both SPARC and x86 deployments, and a DHCP server which you can optionally turn on, configured to act as an AI server. It's pretty much "install and go" and you can immediately start to explore the extensive feature set of AI.

Linux Performance Analysis and Tools

At the Southern California Linux Expo earlier this year (SCaLE 11x) I presented a talk on Linux Performance Analysis and Tools. It’s a great conference, and I was happy to be back.

My talk provided an overview of over twenty performance tools, and I described the problems they solve. At the end of the talk, I summarized some methodologies for using these tools, so that you know when to reach for what.

How many IOPS can a HDD, HHDD or SSD do?

A common question I run across is how many IOPS (IO Operations Per Second) can a storage device or system do or give.

The answer is or should be it depends.

A closer look at the new T5 TPC-H result

You've probably all seen the new TPC-H benchmark result for the SPARC T5-4 submitted to TPC on June 7. Our benchmark guys over at "BestPerf" have already pointed out the major takeaways from the result. However, I believe there's more to make note of.

Moving Oracle Solaris 11 Zones between physical servers

As part of my job in the ISV Engineering team, I am often asked by partners the following question : is it possible to easily move a Solaris 11 Zone from a physical server to another? The short answer is : YES !

Comparing Solaris 11 Zones to Solaris 10 Zones

Many people have asked whether Oracle Solaris 11 uses sparse-root zones or whole-root zones. I think the best answer is "both and neither, and more" - but that's a wee bit confusing. This blog entry attempts to explain that answer.

Best Practices - Live Migration on Oracle VM Server for SPARC

Oracle VM Server for SPARC has supported live migration since 2011, providing operational flexibility for customers who need to move a running guest domain between servers. This can be extremely useful, but there's confusion about when it is the right tool to use, when it isn't, and how to best make use of it. This article will discuss some best practices and "do's and don'ts" for live migration.

Frequency Trails

Frequency trails are a simple and intuitive visualization of the distribution of sampled data. I developed them to study the finer details of hundreds of measured latency distributions from production servers, and in particular, to study latency outliers.

Linux Performance Analysis and Tools

At the Southern California Linux Expo earlier this year (SCaLE 11x) I presented a talk on Linux Performance Analysis and Tools. It’s a great conference, and I was happy to be back.

Systems Performance: Enterprise and the Cloud

Systems performance analysis is an important skill for all computer users, whether you’re trying to understand why your laptop is slow, or optimizing the performance of a large-scale production environment. It is the study of both operating system (kernel) and application performance, but can also lead to more specialized performance topics, for specific languages or applications. Systems performance is covered in my upcoming book: Systems Performance: Enterprise and the Cloud, to be published by Prentice Hall this year.

nmon CPU graphs - Why are the PCPU_ALL graphs lower?

I have been looking at some nmon data from an IBMer looking into a customers machine. The virtual machine (LPAR) is running the Oracle RDBMS with 75 dedicated CPUs - on a POWER7 Power 795 at 4 GHz.

Facebook’s advanced erasure codes

We want our data protected from device failures. When there is a failure we want to get our data back quickly. And we want to pay as little as possible for the protection and the restore. How?

Hello, Manta: Bringing Unix to Big Data

Joyent Manta is a highly scalable, distributed object storage service with integrated compute. Developers can store and process any amount of data at any time where a simple web API call replaces the need for spinning up instances. Joyent Manta Compute is a complete and high performance compute environment including R, Python, node.js, Perl, Ruby, Java, C/C++, ffmpeg, grep, awk and others. Metering is by the second with zero provisioning, data movement or scheduling latency costs.

The death of disks

A forecast says PC shipments with disk drives will drop by a third between now and 2017. IBM is pushing the all-flash datacenter. SSD start ups are claiming that flash is really as cheap as disk with much better performance. Is it the beginning of the end for disk drives?

Manta: Unix Meets Map Reduce

Today Joyent launched Manta: an object store built upon ZFS and Zones, the SmartOS platform, and with a familiar Unix interface as the API. This supports compute jobs such as map reduce, and provides high performance by co-locating zones with the object storage. We also have extensive DTrace instrumentation throughout the product, which we’ve been using in development to help tune performance and respond to performance issues.

Linux-Containers — Part 1: Overview

Linux Containers (LXC) provide a means to isolate individual services or applications as well as of a complete Linux operating system from other services running on the same host. To accomplish this, each container gets its own directory structure, network devices, IP addresses and process table. The processes running in other containers or the host system are not visible from inside a container. Additionally, Linux Containers allow for fine granular control of resources like RAM, CPU or disk I/O.

Oracle 12c: First (and best!) on Solaris

Oracle 12c is now available for download. Notice that support for Solaris SPARC and x86-64 are among the operating systems supported on the first day of availability. [...] As has been the case for some time, Oracle databases are supported in zones.

New White Paper about Upgrade to Oracle Database 12c

This white paper outlines the methods available for you to upgrade and migrate your database to Oracle Database 12c. Learn about different use cases and key factors to consider when choosing the method that best fits your requirements.

Improving Manageability of Virtual Environments

Until recently, Solaris 10 Branded Zones on Solaris 11 suffered one notable regression: Live Upgrade did not work. The individual packaging and patching tools work correctly, but the ability to upgrade Solaris while the production workload continued running did not exist. A recent Solaris 11 SRU (Solaris 11.1 SRU 6.4) restored most of that functionality, although with a slightly different concept, different commands, and without all of the feature details. This new method gives you the ability to create and manage multiple boot environments (BEs) for a Solaris 10 Branded Zone, and modify the active or any inactive BE, and to do so while the production workload continues to run.

AIX and VIOS Minimum Levels for POWER7 and 7+ Hardware

A very nice chart from Richard Milton of IBM on the minimum levels for AIX and VIOS of Power7 and Power7+ hardware.

Ginormous...the new Oracle T5-8 SPARC SuperCluster!

Ginormous...no other way to describe it...the new Oracle T5-8 SPARC SuperCluster...2000+ fast CPU threads, massive memory (DRAM & Flash), 1.2 M IOPS, HUGE storage and bandwidth...WOW! Wanna build a SPARC Cloud? This is it! Multiple virtualization technologies (VM Server for SPARC, and Solaris zones) for elasticity and resource pooling along with Oracle Enterprise Manager Ops Center 12c providing full cloud management capability.

Oracle cranks up SuperCluster with Sparc T5 engines

Anything Big Blue can do, Big Red can do cheaper – and better

Software giant and hardware playa Oracle has launched its high-end SuperCluster T5-8 "engineered system" based on its sixteen-core Sparc T5 processor.

The half-rack configuration of the Sparc SuperCluster populates each node with four of its eight Sparc T5 chips plus 1TB of main memory, eight 900GB disk drives spinning at 10K RPM, four 40Gb/sec InfiniBand ports and four 10GB/sec Ethernet ports. The InfiniBand ports are used to link the two server nodes to each other in an Oracle RAC cluster and to the Exadata storage servers that are also in the rack. Across those two nodes, you have 128 cores and 2TB of memory.

Oracle Database 12c: Finally, a True Cloud Database

In development for roughly four years, Oracle Database 12c introduces so many important new capabilities in so many areas -- database consolidation, query optimization, performance tuning, high availability, partitioning, backup and recovery -- that even a lengthy review has to cut corners. Nevertheless, in addition to covering the big ticket items, I'll give a number of the lesser enhancements their due.

Press Review #23

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

How to Monitor Systems in Enterprise Manager using Ops Center

In this post, we'll use Ops Center to add hardware monitoring to Enterprise Manager. We'll discuss the existing capabilities of Host targets, show how to create an Infrastructure Stack and demonstrate some of the features it provides to Enterprise Manager.

Why SysAdmin’s Can’t Code

Most systems administrators are quick, perhaps too quick, to tell you “I’m not a coder.” Oddly, this admission normally comes after boasting about how many programming languages they know or have used. Why is this? Can this be changed? Here is my 5 step plan on how any SA can become an honest to goodness programmer.

P2V in Ops Center

You can do P2V using Ops Center, but it's not a single-wizard process, and it'll take a bit of tinkering. Basically, you take a flash archive (FLAR) of an existing system, import it, then deploy a host, ldom, or branded zone based on that FLAR.

What is NPIV (N_Port ID Virtualization) and NPV (N_Port Virtualization)?

First, though, I need to cover some basics. This is unnecessary for those of you that are Fibre Channel experts, but for the rest of the world it might be useful...

How to go Physical to Virtual with Oracle Solaris Zones using Enterprise Manager Ops Center

Many customers have large collections of physical Solaris 8, 9 and 10 servers in their datacenters and they are wondering how they are going to virtualize them. This leads to a commonly asked question. Can Enterprise Manager Ops Center 12C be used to P2V (Physical to Virtual) my old servers? Ops Center does not have a single button P2V capability, but it is possible for Ops Center to deploy physical servers, LDOMs and branded zones based on flash archives(flars) that have been taken of your existing physical servers. Ops Center achieves P2V by deploying flars and leveraging its patching and automation capabilities, to make the P2V process consistent, repeatable and as cost effective as possible.

New White Paper Compares SPARC/Solaris to Power/AIX Costs

The Edison Group has just released a white paper. Spoiler alert: the Oracle systems do better. Key findings:

  • Over a five year period, the Power system solution has a total cost of ownership 59 percent higher than the SPARC T5 solution.
  • There's even more of a disparity in cost of acquisition, where the IBM solution is twice as expensive right out of the chute.

Why OS matters: Solaris Users Group testimony

Wednesday evening, a month after the new SPARC servers T5 & M5 launch in Paris, the french Solaris users group, get together to get the latest from Oracle experts on SPARC T5 & M5, Oracle Virtual Network, as well as the new enhancements inside Solaris 11.1 for Oracle Database. They also came to share their projects experiences and lessons learn, leveraging Solaris features : René Garcia Vallina from PSA, did a deep dive on ZFS internal and best practices around SAP deployment and Bruno Philippe explained how he managed to consolidate 100 Solaris servers into 6 thanks to Solaris 11 specific features.

Oracle Solaris Sparc TechDay 2013 : Retour sur l’événement

Oracle-Solaris.fr était présent à cet événement d’envergure pour les technologies Oracle Solaris et Sparc qui s’est déroulé le 15 mai à Paris. L’objectif premier était d’y faire des rencontres, entre administrateurs et ingénieurs systèmes Solaris mais aussi d’y partager ses expériences.

Entitlements and VPs—Why You Should Care

With the POWER7 processor, many changes were integrated into the chip that must be taken into account when defining LPARs. First, understand that POWER7 technology and simultaneous multithreading (SMT4) are all about throughput, and rPerf is a throughput-based performance measurement. Therefore, to take advantage of the server’s full rPerf it’s important to drive all of the threads. However, the way the threads get kicked off has changed with POWER7.

Revealing Hidden Latency Patterns

Response time – or latency – is crucial to understand in detail, but many of the common presentations of this data hide important details and patterns. Latency heat maps are an effective way to reveal these. I often use tools that provide heat maps directly, but sometimes I have separate trace output that I’d like to convert into a heat map. To answer this need, I just wrote trace2heatmap.pl, which generates interactive SVGs.

Exemple: ldom migration with tool ldmp2v

I describe only migration P2V of a physical server in a ldom, the installation and the configuration of Oracle VM Server for Sparc are not specified in this article.

How to Update Only Java on Your Oracle Solaris 11 System

This article describes how to update Java without updating any other software. Java might be updated multiple times in an Oracle Solaris release, so you should follow this procedure periodically.

Oracle Solaris 11 Certification Study Tips

Today on UnixEd.com, author and educator Bill Calkins posts some tips for taking Oracle Solaris 11 certification exams. In this helpful article, he outlines key things to focus on for the most effective use of your study time, including type of exam questions, recommended practice exercises, how to approach and interpret scenarios, as well as recommended reading/study material within his new book, "Oracle Solaris 11 System Administration" which comes out in Jun 2013.

Tuesday 30 April 2013

Press Review #22

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

Permissive and Restricted Policies

Recently I posted two entries about the new Extended Policy functionality in Oracle Solaris 11.1. One demonstrated how to create application sandboxes, and the other how to confine services, like MySQL. Both of these are examples of restrictive policies, whereas privileges have traditionally been used to implement permissive policies, hence the term privilege escalation. The basic functionality and terminology first appeared in Trusted Solaris in 1991. Unfortunately, a draft of the POSIX 1.e Security Specification (withdrawn), used the term capabilities for this functionality, which was subsequently used by Linux developers. Oracle Solaris privileges do share some common terminology with Linux, including the permitted, effective, and inheritable privilege sets. But almost everything else is different.

Midrange Power7+ Servers: The More Oomph You Want, The More It Costs

In last week's issue of The Four Hundred, I walked you though the pricing for various sized configurations of the new Power 750+ and Power 760+ midrange servers using IBM's dual-chip module (DCM) variant of the Power7+ processor. That just looked at the system hardware costs. This week, as I have done in the past, I want to walk you through how the raw computing, operating system, and Software Maintenance costs compare across each processor SKU and how those costs stack up with prior Power 750 machines.

Ksplice Inspector

With so many kernel updates released, it can be difficult to keep track. At Oracle, we monitor kernels on a daily basis and provide bug and security updates administrators can apply without a system reboot. To help out, the Ksplice team at Oracle has produced the Ksplice Inspector, a web tool to show you the updates Ksplice can apply to your kernel with zero downtime.

Oracle Solaris and SPARC Performance, Part 1

To start with: we've just released an update to Oracle Solaris Studio, with compiler optimizations specifically designed to get the most performance out of applications on Oracle T5, Oracle M5, and Fujitsu M10 systems.

And no ... zfs scrub isn't a hidden fsck

I've got quite a number of tweets and mails with the question "But is zfs scrub" not something like fsck. And the answer is "Well ... no".

For Big Data Customers, Top Performance Means High Speed And Low Cost

I hate to quibble with the general manager of IBM’s Power systems division, but his argument that systems speed and power are no longer top priorities for businesses is, to use his own words, “not at all in tune with the market today.”
[...]
As a result, IBM is trying to shift the terms of the debate in order to buy itself some time so that it can try to come up with some sort of story that might blunt the simple facts that Oracle’s new T5 servers have not only posted benchmark results several times faster than comparable IBM products, but are much less expensive as well.

7 big reasons you should be running Solaris on Oracle x86 servers

Oracle’s x86 Systems: The Best x86 Platforms for Oracle Solaris.

Deploying an application in Solaris 11

Glynn takes his time to provide a thorough explanation to anyone who might be entering the world of Solaris 11 and is interested in seeing how things can be put together. Glynn goes over IPS components such as actuators, facets, variants, mediators, a family of pkg* commands, reviews SMF elements such as manifests, profiles, and svcbundle, as well as ties everything into building a zone and performing basic resource management on how the zone consumes network bandwidth.

Oracle Solaris and SPARC Performance, Part 2

This is a perfect example of what we can do by co-engineering the processor, the system, the OS, and the database.

Oracle VM Templates now available on SPARC platforms

Oracle VM Templates provide an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle VM Templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations. Customers have been enjoying the benefits of accelerating software deployment with Oracle VM Templates on x86 platforms. Now we have made Oracle VM Templates available when deployed with Oracle VM Server for SPARC.

Massive Solaris Scalability for the T5-8 and M5-32, Part 1

How do you scale a general purpose operating system to handle a single system image with 1000's of CPUs and 10's of terabytes of memory? You start with the scalable Solaris foundation. You use superior tools such as Dtrace to expose issues, quantify them, and extrapolate to the future. You pay careful attention to computer science, data structures, and algorithms, when designing fixes. You implement fixes that automatically scale with system size, so that once exposed, an issue never recurs in future systems, and the set of issues you must fix in each larger generation steadily shrinks.

Massive Solaris Scalability for the T5-8 and M5-32, Part 2

Last time, I outlined the general issues that must be addressed to achieve operating system scalability. Next I will provide more detail on what we modified in Solaris to reach the M5-32 scalability level. We worked in most of the major areas of Solaris, including Virtual Memory, Resources, Scheduler, Devices, Tools, and Reboot. Today I cover VM and resources.

Oracle Solaris and SPARC (and x86) Performance, Part 4

Simply speaking, east/west traffic is the traffic that rather than going in and out of the data center (which in the world of this metaphor is called north/south traffic), goes between servers in the same data center -- or even in the same physical server.

Oracle takes apparent step toward standardizing on a single chip design

Analysts say the unveiling of midrange and high-end servers running Oracle-built Sparc chips that share the same architecture is a step toward fulfilling the company's post-Sun plans.

Sizing with rPerf but Don't Forget the Assumptions

POWER Relative Performance (rPerf) is often used as a way to approximate the expected difference in performance between two Power Systems servers. Although rPerf is a useful tool, it is important to understand the limitations of using rPerf to provide an estimate the performance of your specific workloads in your particular environment with a new server.

DoD customer receives authority to operate SparcSupercluster

Recently, one of our good U.S. DoD customers purchased a SPARC SuperCluster system and received their "Interim Authority to Operate" on the DoD network. Why is this a big deal? First, allow me provide an overview of the SPARC SuperCluster system.

Oracle Launches T5 and M5 Servers: A New Generation of Oracle's SPARC/Solaris Servers

For longtime Sun customers, the technology refresh will be welcome, leading to improved SPARC server sales right away. But Oracle can be expected to look far beyond its own installed base, planning to grow its total available market (TAM) by taking share from its longtime Unix competitors, IBM and HP. Now that the new T5 and M5 technology is ready, IDC will watch with great interest in coming quarters to see whether the T5 and M5 announcements will lead to near-term market share gain and to a long-awaited turnaround in Oracle's hardware business.

Solaris 11 SRU naming convention change

We're tweaking the naming convention used by Oracle Solaris SRUs (Support Repository Updates) to use a 5-digit version taxonomy.

For example, Oracle Solaris 11.1.6.4.0. The digits represent Release.Update.SRU.Build.Respin. For the above example, Oracle Solaris 11.1 SRU 6.4.

Understanding I/O: Random vs Sequential

I have another article planned for later in this series which describes the inescapable mechanics of disk. For now though, I’ll outline the basics: every time you need to access a block on a disk drive, the disk actuator arm has to move the head to the correct track (the seek time), then the disk platter has to rotate to locate the correct sector (the rotational latency). This mechanical action takes time, just like the sushi travelling around the conveyor belt.

A File System All Its Own

In the past five years, flash memory has progressed from a promising accelerator, whose place in the data center was still uncertain, to an established enterprise component for storing performance-critical data. It's rise to prominence followed its proliferation in the consumer world and the volume economics that followed. With SSDs (solid-state devices), flash arrived in a form optimized for compatibility—just replace a hard drive with an SSD for radically better performance. But the properties of the NAND flash memory used by SSDs differ significantly from those of the magnetic media in the hard drives they often displace. While SSDs have become more pervasive in a variety of uses, the industry has only just started to design storage systems that embrace the nuances of flash memory. As it escapes the confines of compatibility, significant improvements in performance, reliability, and cost are possible.

What is the best platform to run your Oracle Database on?

As a Systems Consultant I am often faced with the following question: What does Oracle recommend as the best platform to run the Oracle DB in large enterprise environments on? Is the Exadata DB Machine the recommended platform? Are SPARC/Solaris servers the way to go? Or should customers consolidate on SPARC SuperCluster setups?

ZFS Analytics

While working with ZFS performance I created a dashboard to get a good overview with lots of different statistics. It's powered by Dtrace, python and graphite. There is a high level of detail but still easy to correlate different statistics.

Oracle have announced new systems based on the new SPARC T5 and M5 processors

Oracle have announced new systems based on the new T5 and M5 processors (thank you Henkis, from It's a UNIX system!, for the following short resume):

  1. T5 16 cores @ 3.6GHz 8MB L3$ 1-8 socket systems PCIe 3.0
  2. M5 6 cores @ 3.6GHz 48MB L3$ 32 socket system PCIe 3.0

The T5 has doubled the number of S3 cores from the T4 and increased the clock frequency to 3.6GHz.

The M5 processor is also based on the S3 core (rebranded M4) clocked at 3.6Ghz but is has 6 cores and 48MB L3$. The M systems supports up to 32 M5 processor so a fully configured systems will have 192 cores and 1536 strands (hardware threads). The M5-32 have 32TB of memory in a single system.

Example of a SPARC T5 configuration:

  • 8 CPU x 16 cores x 8 compute threads = 1024 vCPU
  • 4TB of RAM
  • 8 x 600GB = 4.8TB (10KRPM SAS)
  • 4 x 10GbE
  • 8 RU (Rack Unit)
  • Support Oracle Solaris 10 and Solaris 11
  • Logical Domains (up to 128 by chassis), and Zones (8192 per OS instance)
  • Public list price: 626,000$

Example of a SPARC M5 configuration:

  • 32 CPU x 6 cores x 8 compute threads = 1536 vCPU
  • 32TB of RAM
  • Support Oracle Solaris 10 and Solaris 11
  • Dynamic Domains (up to 4 by chassis), Logical Domains (up to 512 by chassis), and Zones (8192 per OS instance)
  • Public list price: nothing public ;)

All new systems both T5 and M5 supports LDOM (Oracle VM for SPARC), plus the old Dynamic Domain technology for the M5. The M5 gets an ILOM as Service Processor (as for T5 and the x86 server lines), exit the legacy XSCF.

Oracle's new T5 Sparcs boost scalability in chip and chassis

Oracle is launching its much-awaited Sparc T5 processors for entry and midrange servers, along with Sparc M5 processors to effectively replace the iron it currently resells from server and chip partner Fujitsu.

The T5-8 maxxes out at 128 cores, 1,024 threads, and 4TB of memory [...]

At the moment, Oracle is shipping only one box based on the Sparc M5, with 32 sockets, called the Sparc M5-32 (obviously). Fully configured, this big-iron box weighs in at 192 cores, 1,536 threads, and 32TB of main memory. No one has as much memory in a single image today – not IBM, not Silicon Graphics, not HP, and not Fujitsu.

The Sparc M5-32 box puts Oracle/Sun back into big iron.

The SPARC T5 Servers have landed

Having announced the T5 servers doesn't make the T4s go away. It is not a platform replacing technology, but a platform extending one! Oracle is going to offer SPARC T4 and T5 servers side-by-side!

Oracle claims performance crown with SPARC processor

Oracle this morning launched the SPARC T5 processor and servers based on it which the company says are the fastest machines currently in the world.

Ellison aims his first Oracle 'mainframe' at Big Blue.

"These machines deliver better integer performance than the IBM Power series," proclaimed Ellison. "The T5 microprocessor itself delivers better integer performance than IBM's PowerPC chip. Now that is really extraordinary, because IBM has had that lead for a very, very long time for integer rate performance, but that lead now moves over from IBM Power to Sparc T5.

"A lot of people are surprised by this," continued Ellison. "When Oracle bought Sun, a lot of people thought the Sparc microprocessor was a real laggard. There were a lot of people who believed that we would never catch up. Well, we have done better than catch up. We caught up, and then we passed the competition. We passed x86 and we passed IBM Power."

Boom!

So that's quite a "boom." With the launch of the new SPARC T5 and M5 series of servers, we've set over a dozen new performance records, and shown that back in 2010 Oracle did indeed establish a SPARC roadmap that it could execute on.

Hot Chips 24: SPARC T5 Overview

Every year, the best of engineering talent comes together in academia for Hot Chips conference, to present the best system designs.

This paper describes how to implement an increasingly useful type of virtualization feature known as root domains. It also describes an operational model where root domains can be used in conjunction with Solaris Zones for maximum performance and a high degree of flexibility.

Oracle Magazine: SPARC at 25

The SPARC architecture is perhaps the first and longest lasting open and mainstram computing architecture in human history. In Ocrober 2012, Network Management published a reminder for people to attend the "SPARC at 25" event at the Computer History Museum. In November of 2012, Network Management published an short article pointing to the replay of the historic events: SPARC at 25: Past, Present, and Future. Diana Reichardt published an article "SPARC at 25" in the bi-monthly printed Oracle Magazine, covering the event.

New Tab: OpenSXCE New Distribution!

OpenSolaris grew from an Open Source repository to Open Solaris Distribution (for both Intel and SPARC.) Solaris Express Community Edition (Solaris SXCE) was the Intel/SPARC forerunner of Oracle Solaris 11, which abandoned UltraSPARC processors. OpenSXCE, based upon the work of MarTUX, brings OpenIndiana and Illumos back to SPARC as a full distribution, based upon standards such as SVR4 packaging.

Encapsulating Oracle Databases with Oracle Solaris 11 Zones

Implementing higher degrees of isolation can be accomplished by encapsulating each database environment. Encapsulation can be accomplished with physical or logical isolation techniques. Oracle recently certified 11gR2 RAC in Solaris 11 Zones, which is an important capability for database clouds, because it enables strong isolation between databases consolidated together on a shared hardware and O/S infrastructure.

Console logging in Oracle VM Server for SPARC

A new feature in Oracle VM Server for SPARC provides logging for guest domain consoles. Console I/O - all text on the serial console - is logged for all or selected domains, including text that appears before the domain boots Solaris. Logs are stored in files under the directory /var/log/vntsd/domain. These directories are root-owned to protect them from unauthorized access.

ZFS Write Performance (Impact of fragmentation)

In the past few months, George Wilson and Adam Leventhal made significant improvements to how writes are handled in ZFS. In this multi part blog post, I will talk about a benchmark we created to measure improvements in ZFS write performance as we make changes to the OS. In this post, I will talk about the benchmark setup and run. I will show some of the results from this benchmark on Delphix OS. In part two, I will present data and some analysis on the bottlenecks discovered and how they are going to be addressed.

OpenAFS on Solaris 11 x86 - Robert Milkowski

The March Solaris SIG event is about running OpenAFS on Solaris 11 x86. This talk will explore what makes Solaris unique in large OpenAFS deployments with petabytes of storage - how it can save millions of dollars and make debugging and performance analysis much easier and quicker compared to other platforms. Some of the unique features of OpenAFS will be described and how we used them to migrate one of the largest OpenAFS deployments in the world - completely on-line and transparently to AFS clients. Real world examples of how DTrace was used to improve OpenAFS performance and scalability will be discussed.

10Gbit Ethernet, bad assumption and Best Practice - Part 1

We find many people are over optimistic and making assumptions - which can catch them out - we learnt the hard way too.

PowerVM Virtual Ethernet Speed is often confused with VIOS, SEA IVE/HEA speed

I have had a couple of Power systems administrators make assumptions about the virtual Ethernet speed improvements when they install a 10 Gb IVE/HEA in a VIOS which are simply not true. I guess that if three teams have made this mistake then others are about too. So I intend here to put the record straight.

a few words about EtherChannel

Originally, this technology was meant to protect a host against a failure of its network adapter and/or switch (network switch). Additionally, some unscrupulous salesmen claimed a fantastic increase in throughput aka two adapters tied together will double, three adapters tied together will triple throughput of the associated with them EtherChannel adapter – yes, in a salesman pure land of fantasy.

Less known Solaris Features: Highly available loadbalancing

As you may know, Solaris contains an integrated load balancer. It's really easy to configure. Not that well known is the point, that you can make it higly-available in an easy way as well. The following tutorial will give you an overview on the configuration of this feature.

Everyone knows that one of the major problem for consolidating Solaris 10 is network. if each Solaris Zones use a different network (vlan), the configuration of the Global Zone becomes a real headache.

No, ZFS still doesn't need a fsck. Really!

Friday was a day that i called once 10k day. More 10.000 visitors to my blog in one day. Saturday was similar. This surge was create by an link on news.ycombinator.com article i wrote roughly four years ago about ZFS: No, ZFS really doesn't need a fsck.

Just wanted to express that four years later and a lot more experience with ZFS later, 12 years after ZFS saw the light of the word, i'm more of the opinion that ZFS doesn't need a fsck than ever.

Press Review #20

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

Network Virtualization and Network Resource Management

After discussing Oracle VM, OS virtualization, and some aspects of resource management in the previous articles of this series, this article will now cover a special area of resource management and virtualization of resources: network virtualization and network resource management.

The network is a special shared resource that glues all the virtual machines (VMs), zones, and systems together and provides a communication channel with the world. Thus, the network is a very important layer of the virtualization stack.

Oracle: Solaris 10 Update 11 Released!

Solaris 10 was launched in 2005, with ground-breaking features like: DTrace, SMF (Services), Zones, LDom's, and later ZFS. The latest, and perhaps last, update of Solaris 10 was expected in 2012, to co-inside with an early release of the SPARC T5. In 2013, Oracle released yet another update, suggesting the T5 is close to release. The latest installment of Solaris 10 is referred to as 01/13 release, for January 2013, appears to be the final SVR4 Solaris release, with expected normal Oracle support extending to 2018. Many serious administrators will refer to this release as Solaris 10 Update 11.

IBM Announces updated Power710 to 740 and brand new Power 750/760

This time it was very different as looking at the POWER7+ Power 750/760 s we thought: "Hang on!! We have seen this before! It looks just like a Power770 but one U taller (5U instead of 4U)." So it is a completely different machine inside - if it was not for the 32 CPU cores in the Power 750 model and so fits in the uprated range in the same place, it should have been given new number. I guess using the same number means we all know where it fits. The 760 is very much the same machine but with all the higher features as the 750 but you can't convert between them.

Consommation CPU & Gestion mémoire (2ème partie)

Cela fait déjà un petit moment que j'ai écrit la 1er partie de cet article et j'imagine que vous aviez hâte dans connaître le dénouement ?

Pour rappel, la forte consommation CPU (notamment le temps system) provenait de l'agent Grid d'Oracle. Suite à la modification dans le kernel du mode d'allocation des pages (pg_contig_disable), la charge CPU semblait se répartir plus équitablement entre le temps system et le temps user. Mais... quelque chose me choquait encore...

Création d'un serveur AI personnalisé (archi Sparc)

Après avoir créé vos repos (méthode pas-à-pas disponible dans un précédant article), il est temps de créer votre serveur AI personnalisé. Je vais découper ce sujet en deux partie, un article sur l'architecture Sparc et un autre sur l'architecture x86. Et pourquoi donc ? J'utilise deux méthodes d'initialisations différentes, wanboot pour l'architecture Sparc et la paire pxe/dhcp pour l'architecture x86. Du coup je préfère distinguer ces deux architectures.

Observations : analyse d'un core "...Unable to fork..."

Les apparences sont quelques fois trompeuses… Petite démonstration confirmant cet adage.

Situons le contexte : plusieurs DBA Oracle nous remontent un incident sur un de leur serveur. Le symptôme étant le suivant : connexion impossible. Après une rapide vérification le diagnostic initiale semble être le bon. Petite connexion au déport console du serveur et me voilà devant un message des plus explicite « Unable to fork ». Hop, je provoque un petit panic et en avant pour une petite analyse.

Création d'un serveur AI personnalisé (archi x86)

Lors d'un précédent article, j'ai traité la mise en place d'un serveur AI personnalisé pour l'architecture Sparc (déploiement via Wanboot). Comme convenu, je vais traité ici la mise en place d'un serveur AI mais sur l'architecture x86. La différence entre ces deux architectures (d'un point vue installation) se situe principalement sur la phase d'initialisation juste avant le début de l'installation.

Sur une architecture x86, la phase d'initialisation est le plus souvent exécutée par le couple pxe / dhcp. Il est donc nécessaire de configurer un serveur dhcp permettant d'interpréter la requête pxe que le client enverra. Il peut s'agir d'un serveur dédié ou mutualisé avec le serveur AI. Dans mon exemple ci-dessous, il n'y a qu'un serveur pour la configuraton dhcp et AI.

Best Practices - Top Ten Tuning Tips

Oracle VM Server for SPARC is a high performance virtualization technology for SPARC servers. It provides native CPU performance without the virtualization overhead typical of hypervisors. The way memory and CPU resources are assigned to domains avoids problems often seen in other virtual machine environments, and there are intentionally few "tuning knobs" to adjust.

However, there are best practices that can enhance or ensure performance. This blog post lists and briefly explains performance tips and best practices that should be used in most environments.

Oracle VM Manager used with SPARC - demo

Rather than describe this in text, the best thing to do is show it in demo format. Fortunately, the wizardly Steen Schmidt has produced outstanding Youtube videos showing Oracle VM Manager in action at https://www.youtube.com/user/gandalf3100.

Serial Console with VirtualBox on Solaris host

First make sure you have nc(1) available it is in the pkg:/network/netcat package.

Then configure COM1 serial port in the VM settings as a pipe. Tell VirtualBox the name you want for the pipe and get it to create it.

The Year in Review

As 2012 comes to a close, I thought it would be a good time to look back at some of the changes that have been made to the Trusted Extensions features in Oracle Solaris.

Linux YAMA Security equivalents in Solaris

The Linux YAMA Loadable Security Module (LSM) provides a small number of protections over and above standard DAC (Discretionary Access Controls). These can be roughly mapped over to Solaris as follows...

Itanium: Another Step Closer to Death

Intel had produced the Itanium architecture to compete in the higher-end 64 bit arena and eventually sun-set their aging 32 bit x64 architecture. With the release of AMD's x64 architecture, and vendors such as Sun Microsystems abandoning the Itanium roadmap for AMD x64 - pressure was placed upon Intel to include 64 bit instructions in the x86 chipset. Now with Intel x86 supporting 64 bit processing, there is little reason for Itanium to exist, placing pressure on remaining Itanum system vendors.

How to Update A Linux Kernel Without Rebooting

The uptrack-update command applies patches to your Linux kernel while your system is still running. A Ksplice Uptrack subscription gets you so much more than rebootless kernel updates. Here are some details.

Configuring a Basic LDAP Server + Client in Solaris 11

Solaris 11 ships with OpenLDAP to use as an LDAP server. To configure, you're going to need a simple slapd.conf file and an LDIF schema file to populate the database.

How to Configure the Linux Out-of-Memory Killer

This article describes the Linux out-of-memory (OOM) killer and how to find out why it killed a particular process. It also provides methods for configuring the OOM killer to better suit the needs of many different environments.

Observation : fastresync et ACFS

Petite observation lors d’une recette cluster d’un Oracle RAC 11gR2 sur Solaris 10 Sparc. Pendant le test suivant « perte d’une baie SAN », nous avons observé un petit problème lors de la resynchronisation des diskgroups ASM utilisant des volumes sous ACFS. Nous nous attendions à utiliser la fonctionnalité fastresync et pourtant...

Announcing Oracle Linux 6.4

The Oracle Linux team is pleased to announce the availability of Oracle Linux 6.4, the fourth update release for Oracle Linux 6.

Friday 1 February 2013

Press Review #19

Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:

Oracle Linux Ksplice offline client

By introducing the offline client, customers with Oracle Linux Premier or Oracle Linux Premier Limited support can create a local intranet yum repository that creates a local mirror of the ULN ksplice channel and just use the yum update command to install the latest ksplice updates. This will allow customers to have just one server connected to the oracle server and every other system just have a local connection.

Resource Management as an Enabling Technology for Virtualization

In this article and the next, we will cover some enabling technologies for virtualization. Here, we discuss IT resource management as an enabling technology for virtualization.

Oracle Premier Support for Oracle Solaris 10 extended by 3 years - now ends January 2018

Release        GA Date         Premier Support Ends    Extended Support Ends   Sustaining Support Ends
Solaris 10      Jan 2005        Jan 2018                Jan 2021                Indefinite
Solaris 11      Nov 2011        Nov 2021                Nov 2024                Indefinite

BrandZ Solaris 10 (exemples de migration P2V et V2V)

Comment réduire efficacement les coûts d'une infrastructure de serveurs sous Solaris 10 ? En les consolidant !! Cela va de soi, la forte utilisation des zones en est un très bonne exemple. Oui mais... Pourquoi ne pas utiliser les nouvelles possibilités qui s'offrent à nous : Un serveur sous Solaris 11 et des brandZ Solaris 10.

Je vous présente deux exemples rapides de migration d'environnements Solaris 10 physique (P2V) et Solaris 10 zone (V2V) sur un serveur Solaris 11.

Virtualization Performance: Zones, KVM, Xen

At Joyent we run a high-performance public cloud based on two different virtualization technologies: Zones and KVM. We have historically run Xen as well, but have phased it out for KVM on SmartOS. My job is to make things go fast, which often means using DTrace to analyze the kernel, applications, and those virtualization technologies. In this post I’ll summarize their performance in four ways: characteristics, block diagrams, internals, and results.

TPM Key Migration in Solaris

"TPM" stands for "Trusted Platform Module," a hardware device that provides many security functions, including storage of encryption keys. [...] In Solaris 11.1, Wyllys Ingersoll added the ability to migrate keys from one TPM to another TPM. TPM migration is is especially useful when upgrading hardware, migrating a system to a new platform, or after reinitializing the TPM. The following describes this new feature.

What's new in User Rights Management

Way back in Solaris 8 we introduced an extensible database, user_attr(4), where we could maintain the security attributes of each user. Originally the database included just three properties: roles, auths, and profiles. [...] Since then we have been adding new properties in each Solaris release, while preserving backward compatibility in both the file /etc/user_attr and the corresponding LDAP schema. To avoid dealing with an alphabet full of new options, we standardized on the -K option, which can be used to set the values of any property.

LDoms IO Best Practices

Stefan Hinker discuss different IO options for both disk and networking and give some recommends on how you to choose the right ones for your environment. A couple hints about performance are also included.

T4 & the Red Crypto Stack

Heinz-Wilhelm Fabry and Stefan Hinker show how to use encryption and other security mechanisms throughout the red stack to deploy a quite well secured database.

Why Oracle CEO Larry Ellison Is So Bullish on Sun Hardware

In the past decade, Oracle has acquired about 90 companies. And out of all of those deals, Larry Ellison recently cited the 2009 acquisition of Sun Microsystems as “the most strategic and profitable acquisition Oracle has ever made.”

ZFS Compression Enhancements in illumos

The ZFS code in illumos has gained another differentiator thanks to the hard work of Saso, who integrated LZ4 improved compression into our code base.

Solaris 11 IPS Concepts, Issues, and Workarounds

Image Packaging System (IPS) is a single tier packaging architecture which in Oracle Solaris 11, and other Oracle Sun products such as Oracle Solaris Cluster 4.x, replaces the previous SVR4-based dual tier packaging and patching architecture.

Oracle Delivers On SPARC Promises

In a nutshell, SPARC/Solaris customers are looking at a predictable long-term future of improved and very competitive performance and price-performance scaling for Oracle hardware, especially when coupled with Oracle software in its “engineered systems.” Oracle and IBM will remain in a strong competition for performance and price-performance across a variety of workloads, and competitive pressures will ensure a decade of strong systems platforms for high-end UNIX workloads regardless of the eventual fate of HP’s Itanium platforms.

How to Configure a Failover Guest Domain in an Oracle Solaris Cluster

The configuration described in this article enables the protection of guest domains from planned and unplanned downtime by automating the failover of a guest domain through restart on an alternate cluster node. Automated failover provides protection in case there is a component outage or the guest domain needs to be migrated for preventive maintenance.

Compliance reporting with SCAP

In Solaris 11.1 we added the early stages of our (security) Compliance framework. We have (like some other OS vendors) selected to use the SCAP (Security Content Automation Protocol) standard from NIST. There are a number of different parts to SCAP but for Compliance reporting one of the important parts is the OVAL (Open Vulnerability Assesment Language) standard. This is what allows us to write a checkable security policy and verify it against running systems.

Fujitsu launches 'Athena' Sparc64-X servers in Japan

Japanese IT giant and long-time Sparc partner with Sun Microsystems and now Oracle has let slip the details on its "Athena" line servers based on its own sixteen-core Sparc64-X processors, which bear the same code-name inside Fujitsu. And it looks like Oracle is going to be reselling them, too.

Evaluating Oracle Solaris 11 from Inside Oracle VM VirtualBox

This article describes how to evaluate Oracle Solaris 11—without having to install it on the bare metal—by importing it into Oracle VM VirtualBox, configuring it, exploring basic administrative tasks, and connecting to the network.

grub2 : configuration de la console série

Depuis Solaris 11 update 1, le chain loader utilisé pour les plateforme x86 est GRUB2. Le fichier de configuration présent dans GRUB (menu.lst) est remplacé par un nouveau fichier nommé grub.cfg. L'édition de ce fichier est normallement déconseillé, du coup la mise à jour s'effectue via la commande bootadm.

How to Use Signed Kernel Modules

Loadable kernel modules allow you to add code to a running Linux kernel. Oracle's Unbreakable Enterprise Kernel provides signed kernel modules to further protect the kernel. This article explains how to use this feature.

Updating and patching Oracle Linux using yum and Ksplice

Oracle Linux provides two complimentary technologies for patching and updating the operating system. [...] This is where Ksplice enters the picture. It is a technology that allows you to apply critical fixes to the Linux kernel at run time, without the need to reboot your system. This is a feature that is unique to Oracle Linux.
