Todays (Tuesday) Oracle WaterWorld Sessions…

It was raining quite hard this morning. Fortunately I brought my “Fujitsu Siemens” umbrella from 2 years ago. Debra Lilley was quick to point out the company name change… :)

Today was another day heavily based around the Unconference in Moscone West. Four of the six presentations I went to today were at the unconference. Here’s what I saw today:

  • What’s New in Eleven … Dot Two (that Oracle won’t be talking about) by Daniel Morgan: A quick romp through some of the stuff that is new or updated in the latest release that’s not sexy enough for the marketeers to focus on.
  • Oracle Indexes: Q & A Discussion by Richard Foote: Richard was hoping we could all spend the hour discussing David Bowie, but the audience wanted to know about indexes. The session kinda turned into the Richard and Jonathan roadshow. Fortunately they agreed on most points. :)
  • Under The Hood of Oracle Clusterware with live demo Part I & II by Alex Gorbachev: This was a 2 hour unconference session where Alex explained the architecture of Oracle Clusterware, then proceeded to demonstrate a whole bunch of stuff including scenarios causing node eviction.
  • Current Trends in Real-World Database Performance by Andrew Holdsworth: I try to get to the sessions by the Real World Performance Group each year, just to make sure there’s not something new I’ve missed. It gives me a warm fuzzy feeling. :)
  • The Terabyte Hour with the Real-World Performance Group by Andrew Holdsworth: This session involved a live ETL process loading 1 Terabyte of data in flat files into a Exadata V1 Database Machine running 11gR2. Once the data was in they gathered stats, did a bunch of transformations and issued a bunch of heavy SQL statements at it to show the performance. Very impressive to get all this one in 50 minutes. Nearly all the processing was CPU bound, so it would be interesting to see the same demo on the V2 machines. Even better to do the Pepsi Challenge and have then side by side doing it…

I’ve just noticed I’m about 90 minutes late for the blogger get together. I better get moving…

Cheers

Tim…
