Oracle Linux Forum

This forum includes live chat so you can tell Wim, Lenz, and the gang what you really think.

Linux Forum - Tuesday March 27

Since Oracle recently made Release 2 of its Unbreakable Enterprise Kernel available (see Lenz's blog), we're following up with an online forum with Oracle's Linux executives and engineers. Topics will be:

9:30 - 9:45 am PT
Oracle's Linux Strategy

Edward Screven, Oracle's Chief Corporate Architect and Wim Coekaerts, Senior VP of Linux and Virtualization Engineering, will explain Oracle's Linux strategy, the benefits of Oracle Linux, Oracle's role in the Linux community, and the Oracle Linux roadmap.

9:45 - 10:00 am PT
Why Progressive Insurance Chose Oracle Linux

John Dome, Lead Systems Engineer at Progressive Insurance, outlines why they selected Oracle Linux with the Unbreakable Enterprise Kernel to reduce cost and increase the performance of database applications.

10:00 - 11:00 am PT
What's New in Oracle Linux

Oracle engineers walk you through new features in Oracle Linux, including zero-downtime updates with Ksplice, Btrfs and OCFS2, DTrace for Linux, Linux Containers, vSwitch and T-Mem.

11:00 am - 12:00 pm PT
Get More Value from your Linux Vendor

Why Oracle Linux delivers more value than Red Hat Enterprise Linux, including better support at lower cost, best practices for deployments, extreme performance for cloud deployments and engineered systems, and more.

Date: Tuesday, March 27, 2012
Time: 9:30 AM PT / 12:30 PM ET
Duration: 2.5 hours

Who the Linux Developer Met on His Way to St. Ives

For some reason I still remember this nursery riddle:

"As I was going to Saint Ives
I met a man with seven wives
Each wife had seven sacks
Each cat had seven cats
Each cat had seven kits
How many were going to St Ives?

The answer, of course, is one. More about the riddle here.

Little did I know, when I first learned it, that this rhyme would help me understand the Oracle Exadata Database Machine. Miss Blankenship, please forgive me:

As I was going to St Ives
I met a man with 8 Oracle Exadata Machines
Each machine had 8 sockets
Each socket had 8 cores
Each core had 2 threads
How many CPU's were going to St Ives?

If your i-phone has hobbled you to the point that you can no longer do simple arithmetic in your head, you can get the answer to that riddle by listening to these podcasts (the first one even provides notes):

Podcast: How Oracle Linux Was Optimized for the Oracle Exadata Database Machine

Turns out that when you use off-the-shelf components to build a NUMA system like the Exadata, you lower your hardware costs, but you increase the software work that must be done to optimize the system. Oracle Linux already had a set of optimizations well suited to this task. Chris Mason, director of Linux kernel engineering at Oracle, describes the process engineering used to optimize Exadata's integrated stack, touching everything from storage, to networking, the CPU, I/O speeds, and finally the application. Great Q&A, too.

Podcast: What's So Great About Oracle's Unbreakable Enterprise Kernel?

It's easy to replace your tired rust-bucket of a Linux kernel with the chromed-out Unbreakable Enterprise Kernel from Oracle, but why would you? Sergio Leunissen, Oracle Vice President, and Lenz Grimmer, blogger extraordinaire, explain why it's worth your time to use the Unbreakable Linux Kernel. Sergio and Lenz explain why Oracle went to the trouble to engineer its own kernel, what's included in Release 2, how it is tested, how it is optimized for the Oracle stack, the close relationship with the Linux community, and what benefits it brings developers and sysadmins.

Where to Get It, How to Use It

As you may have already heard, Release 2 of Oracle's Unbreakable Enterprise Kernel for Linux is now available. Here are some resources to help you get started.
