Oracle Enterprise Linux Certification - Yes, You Heard Right...

What to do during those... erm... 'uncertain' times? Why, branch out of course... and that's what lead this intrepid blogger to consider questions like "what's fun?", "what haven't I done in a while?" and "what might be relevant to our imminent New Overlords?".

Relax, Sun Blog Police, that's all Imma say about Snorcle, OK?

I picked 'Oracle Enterprise Linux Certification'. Just cuz. Just cuz I enjoy Linux almost as much as I do OpenSolaris. Just cuz I went and gots me a Red Hat Certified Technician certificate a few years back, also "Just Cuz."  And just cuz it might even be applicable in future endeavors.

For those of you whose knowledge of OEL (sometimes referred to by the overarching 'Unbreakable Linux' moniker) rivals that of Solaris -- Oracle takes the Red Hat code base, strips out any Red Hat identity, slaps on Oracle veneers, and supports the snot out of it. That allows Mssr. Ellison to raise the hackles of yet another rival. Which is good. I'm thinkin'...

Anywho, OEL 5 is RHEL 5 with a different shade o' red paint. If you know RHEL, you know OEL.

An OEL Administration Associate certificate requires the passing of two two-hour multiple-choice exams. If you have a comparable certifications already, you might be given a pass on the first exam - indeed, my RHCT certificate allowed me to test out of the first exam. The second, a more in-depth sysadmin exam, is 113 questions over two hours. Not hands-on, as Red Hat exams are, but also with a lot of 'choose all th apply' questions. Far from trivial stuff, but quite doable if you prepare adequately.

So, as of today, I add the OEL Admin Associate designation to my list of... umm... things. Right along side the RHCT and Solaris and Java Certifications. And my collection of Wired Magazines -- can't forget those!

Cuz, you know, this just seemed like the Thing To Do...

Drupal Performance: Solaris vs Linux

I posted final numbers today as to how Drupal 5 performs on a small Sun server, comparing Solaris 10 to SLES 10 (two of the OS offerings available from Sun on this server). The intent of this test was to see how Drupal behaved under increasing load (in this case, Guest hits on the Main Page). I'm pleased to report that Solaris (with the latest CoolStack) appears to provide better throughput, better response time, and lower incidence of 'Server Busy' errors under load.

Let me, at this point, state for the record.. yes, I would have published these results even if the outcome had been the other way 'round. One of the rules we live by in Sun ISV Engineering Open Source is that of transparency. If we set out to test something, it's to determine and share the reality, not the spin. We had a hunch that CoolStack would provide a huge performance improvement, but that was only a hunch. I'm sure that, at some point in the future, we could also find that a well-tuned Drupal-on-LAMP offering meets or beats this Solaris performance - it is, after all, the same hardware.

Lots more Drupal testing to come from from us in the weeks and months to come. Wanna see something in particular? Let us know here or here or right here in the Blog Comments!
