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
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
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
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
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
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
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
- step: "scsinstall -u update" on all cluster nodes, while the system is
- 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
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".
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

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
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
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
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:
- Dynamic Domains
- Oracle VM Server for SPARC
- 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
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.
