Press Review #25
Here is a little press review mostly around Oracle technologies and Solaris in particular, and a little lot more:
How to Get Started Using DTrace on Oracle Linux
We all hate slow code. Bunch of princesses is what we've become. During the American Civil War, they had to deliver their text messages by horseback! It took weeks! And half the time, they got blown off their horse by a cannonball to the neck!
Today? Today we have to have our stuff back in milliseconds, or we start tweeting about it. So, if you're developing or deploying applications, how do you keep them performing at the speed to which we have become accustomed? DTrace, of course.
What's up with LDoms: Part 7 - Layered Virtual Networking
Back for another article about LDoms - today we'll cover some tricky networking options that come up if you want to run Solaris 11 zones in LDom guest systems. So what's the problem?
Core files filling important filesystems? Want email alerts about each core dump?
I got asked these questions recently and had to go look the subject up ... again! I seem to have forgotten some of the details and then I thought I would use some new features of AIX for the second part. In the distant past there was various way to stop core files being dumped in to the current working directory of the program that failed. In AIX 5.3, AIX 6 and 7, the "chcore" command does all the hard work for us by letting us...
Availability Best Practices on Oracle VM Server for SPARC
This is the first of a series of blog posts on configuring Oracle VM Server for SPARC (also called Logical Domains) for availability. This series will show how to how to plan for availability, improve serviceability, avoid single points of failure, and provide resiliency against hardware and software failures.
In computer performance, we’re especially concerned about latency outliers: very slow database queries, application requests, disk I/O, etc. The term “outlier” is subjective: there is no rigid mathematical definition.
How Oracle Solaris Makes Oracle Database Fast
Is choosing an operating system all that's important any more? After all, virtualization lets sysadmins choose the OS that best matches the workload they plan to put on each virtual machine. And Red Hat Linux on Intel is cheap and ubiquitous enough to work for most anything. Right?
We don't think so.
National Security, the "two man rule" and Solaris
[...] Luckily, Solaris 10 and 11 have all the tools to assist in creating a "two man rule." In fact, we published a paper on the topic in 2005. Its comprehensive role and profile based collection of authorizations ensure that only user with the proper authorizations are allowed access to administrative tools. Solaris can be configured so that one user has the role of "Security Admin" while another user has the role of "System Admin."
How to Initialize an Oracle Linux System
SUSE Linux to Oracle Linux Migration Guide
This article, Part 1 in a series that compares and contrasts Oracle Linux with SUSE Linux, describes registering the software, booting, and system initialization.
How to Install Oracle 12c RAC: a Step-by-Step Guide
Okay, back to school folks, back to school :). As with any new product, our long learning journey starts with an installation on a sandbox environment. To get you up to speed with Oracle 12c RAC and let you focus on important stuff (e.g. features research), I have put together detailed step-by-step installation instructions.
Are you among the people migrating workloads from IBM AIX to Oracle Solaris 11? Even if you have not yet begun this migration, you will benefit from the knowledge contained in these resources...
Overview of Linux Kernel Security Features
In this article, we'll take a high-level look at the security features of the Linux kernel. We'll start with a brief overview of traditional Unix security, and the rationale for extending that for Linux, then we'll discuss the Linux security extensions.
Extra huge database IOs, part 3
This is part 3 of a number of blogposts about huge Oracle database IO’s.
Oracle Continues Linux Leadership with 80% Year over Year Growth for Oracle Linux
Oracle today announced that customers and partners continue to rapidly adopt Oracle Linux to increase the scalability, reliability and performance of their critical applications and systems.
Availability Best Practices - Availability Using Multiple Service Domains
Oracle VM Server for SPARC lets the administrator create multiple service domains to provide virtual I/O devices to guests. While not mandatory, this powerful feature adds resiliency and reduces single points of failure. Resiliency is provided by redundant I/O devices, strengthened by providing the I/O from different service domains.
Availability Best Practices - Example configuring a T5-8
This article continues the series on availability best practices. In this post we will show each step used to configure a T5-8 for availability with redundant network and disk I/O, using multiple service domains.
Power Ask the Experts Technical Event UK - Session Downloads
The fifth POWER Ask the Experts is a one day customer technical event in the UK which ran in Manchester and London on 15th/16th July 2013. It proved to be a very popular free event. We had well over a 100 people attend which was a mixture of customers, a few Business partners and some IBMers.
Oracle Linux Gains Momentum
In October of 2006, Oracle's CEO Larry Ellison announced a bold new venture, with his company's own Linux distribution.
Nearly seven years later, Oracle Linux continues to power ahead.
"There are nearly 11,000 customers running Oracle Linux on non-Oracle hardware," Wim Coekaerts, senior vice president of Linux and Virtualization Engineering, Oracle, told ServerWatch.
Top 5 Processor Myths
When the microprocessor was invented in 1974, the computational power packed into the 2.6-GHz, dual-core Intel Core i5 that’s in the laptop I got when I joined Oracle two weeks ago would have been unimaginable.
The Ksplice differentiator
It's been exactly two years since we acquired a small startup called Ksplice. Ksplice as a company created the zero downtime update technology for the Linux kernel and they provided a service to their customers which tracked Linux kernel security fixes and providing these fixes as zero downtime Ksplice updates.
