Oracle Enterprise Manager 11g Documentation Available Online

There you can find the list of EM 11g new features. After I quickly skimmed through it I could mention few areas…Here is the surprise you might not have expected — you now need to install Oracle WebLogic Server 10.3.2 (Oracle Fusion Middleware 11g Release 1 Patch Set 1) as a pre-requisite to Oracle Grid Control installation.

When Was Your Last Disaster Recovery Test?

A regular DR procedure validation is designed to minimize the risk of a broken process to go unnoticed. If the failure is detected during a regular switchover process, you are prepared to handle it way better (or potentially just leave services on the currently primary site) than during emergency failover when you get to the “Oh shit!” moment under the tremendous pressure to get services back.

Nobody Killed OpenSolaris — Stop the FUD!

I’m tired reading all over the internet — Oracle taking back OpenSolaris, Open Solaris May Die?, Solaris Is Dead, Save Open Solaris, Oracle taking back OpenSolaris. I’m so sick of it! I see that some don’t even know the difference between OpenSolaris and commercial Oracle Solaris (former Sun Solaris 10)! Wake up people! Oracle did make commercial Solaris 10… eh… commercial, that is.

Meet the First Oracle ACE Director in MySQL — Sheeri Cabral

I’m excited to share the news that Oracle ACE program has been extended to cover MySQL community now and Pythian’s Sheeri Cabral has become the very first Oracle ACE Director in MySQL expertize area. It’s a special privilege for me to blog about it because I had a pleasure to nominate Sheeri in the first place. Being an Oracle ACE Director myself and knowing what’s involved, I believed that if Oracle ACE program is extended to MySQL, Sheeri must be the number one candidate.

Hotsos Symposium 2010 — Battle Against Any Guess Is Won

What’s unusual about this session is that it’s not some technical stuff that I usually do but a more conceptual and motivational talk. Could I pull it off? Well, I think it went fairly well in general even though I did identify few rough places and my lack of English language mastering. Might need to work a little bit more on the flow of the presentation. We had quite a few good laughs. Later, people in the next hall were asking about it and Dan was making the jokes on the stage so it must have been loud. Anyway, I think nobody fell asleep and I managed to get people thinking about the topic. I received many “thank you” notes yesterday and compliments on a good session so by the end of the day I was more and more pleased. Thanks everyone for attending and especially big thanks to those of you who brought to my attention examples from their own battles. If you have more to discuss — contact me by email (my last name) {at} pythian.com.

IBM Storage Fails Too Often, so Let’s Switch to EMC…NOT!

A couple weeks ago I did a short blog post about SAN storage failures and how people are blinded by all the bells and whistles that are supposed to make storage arrays 100% reliable and failsafe. My conclusion was that there is no way to avoid storage failures, and that a better way is to anticipate those failures and be ready to handle them with minimal service impact.
