Video fragments of my session posted at the end — read on.

I arrived at Omni Mandalay Hotel on Sunday evening with Dan Norris. I was flying through Chicago and it turned out that Dan was on the same flight and only few rows behind me. Small world.

Preparations for the conference were very chaotic on my part and, of course, I didn’t have either of my presentations ready. I was very stressed and getting sick as well — it looked like a complete disaster waiting to happen. I’d like to say that I was feeling like Doug Burns as he often managed to get sick just before a conference. Of course, I worked on my slides for the last few days as well as on the flight and presentation was slowly getting there but boy was I tired!

I quickly said hello to the crowd in the bar on the way to my room and rushed away to do some more damage to my slides. And then I had a brilliant idea — I could still see one of my best mates and do something good about my presentation! I asked Doug if he was interested in the preview (he probably wasn’t interested but he couldn’t say it to me) especially that my session wasn’t on his original agenda. Of course, that would mean that he had to leave a bunch of other good friends and spend some time tete-a-tete. Knowing Doug, this is some of the hardest thing to ask from him but it shows how good of a friend he is! (Plus, everyone thinks that he is anti-social anyway. Shhhh!)

Just a quick post to get myself back into blogging mode. Recently in IRC (#oracle on freenode, to be precise), a fresh face asked if the Block Change Tracking file ever shrinks. She had been worrying about the file in her instance continuing to grow. A number of us speculated (non-BAAG!) that perhaps taking an RMAN backup would somehow purge the file of what it was keeping track of, and then the magical Oracle fairies would promptly resize it for us. Needless to say, I was hesitant to take this theory forward with Alex Gorbachev aware of my home address.

After setting up Oracle 10.2.0.1 on a nice VirtualBox image
(more on that in another post) running CentOS 5, I began to do some reading. For some reason, actually reading the official tahiti docs was last on my list. A search of the 10gR2 docs quickly yielded this (from RMAN Incremental Backups):

First of all “the before” time is over — I’m done with my presentation. It’s been the first slot of the day — 8:30 and Cary Milsap was presenting in another hall so what chances do I have to get people in? It turned out that some people actually did show up and quite a few considering the circumstances.

I have mixed feeling on the results. The presentation started very well and I managed to wake people up at the very beginning — thanks to the “equipment” I had at hands (thanks Marco and Riyaj!). You can spot one of them on the photo (thanks for the photo Marco):
