“Oracle RMAN 11g Backup and Recovery” book

One of the most critical skills of any Oracle DBA is the ability to prevent a system crash and to restore and recover the system in case of a disaster. The “Oracle RMAN 11g Backup and Recovery” book by Robert G. Freeman and Matthew Hart is a resource that can definitely help to acquire the skill. I recently received my early copy of it, and am honored to have contributed to Chapter 5 “Oracle Secure Backup” for it.

Stats Overflow

Recently I’ve been puzzled with the performance difference observed between 11GR1 and 11GR2. As part of the investigation I’ve decided to compare session stats from both 11GR1 and 11GR2 and found that there is a big difference for session cursor cache hits. But the number of session cursor cache hits I’ve been observing in 11GR2 just didn’t made any sense while being absolutely fine in 11GR1. An overflow was certainly a possibility, though in 2010, it’s not like someone should be counting every bit especially if they didn’t in 11GR1! Anyway it was worth a shot so I’ve decided to check it out…

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.

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.
