Installing TOra with Oracle Support on Ubuntu 10.04 (Lucid Lynx)

Once again into the breach. The release of Ubuntu 10.04 is at hand. I’ve been playing with “Lucid” for a couple of months now but since we’re in beta2 with the release candidate soon to follow, I thought I would really sit down and get my normal app stack working including TOra. All in all the instructions are mostly the same as last time around, with a couple of new improvements, caveats and quid pro quo.

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.

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.

Where did the filter come from?

There has been a recent thread on ORACLE-L where the poster asked why there is an extra filter predicate which appears when functions are being used in the where clause. We can observe the behavior using the following test case.

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.
