Here are the slides of the presentation I did yesterday: OOW2010 Christian Bilien. The room was full and I noticed a number of people were standing at the back of the room, hope the awful sound did not add too much to the pain.

Oracle Open World 2010

I just took a look at the OOW Oracle Content Manager: looks like my room is almost full. I suspect the Exadata has something to do with it.  My session details are:

Large-Scale Oracle RAC (and Sun Oracle Database Machine) Scalability Design
Date: 20-SEP-10 Time: 14:00-15:00 Venue: Moscone South Room: Rm 236

My presentation main bullets are listed below. Hope this will not deter too many people. The presentation has a lot (too many ?) figures into it. As I will not have enough time to elaborate, I plan to post the presentation on this blog later in the week.

  • Capacity Management: the performance edge
  • The cornerstones of data base scalability
  • Data Base storage scalability
  • I/O time and the physic of distance
  • Exadata: a technological leap in capacity management
  • Brute force scans
  • Projection
  • Restriction
  • Storage indexing
  • (Bloom) join filter pruning

This blog is inactive (at least for the time being)

Filed under: Uncategorized — christianbilien @ 7:53 pm

It’s been more than 2 years and a half since I last blogged on Oracle performance. I had the feeling I could not carry on this extra time activity when I started managing a 20 people DBA team and 4 technologies (including 2  Oracle competitors- Microsoft and Sybase which has ASE and IQ). It would have been difficult in the first place not to be labeled Oracle-biased by Oracle competitors if I did. I also moved from in-depth troubleshooting, which provided me material to write, to architecture design. This is more on assessing business requirements and translating them into technologies, with an emphasis on scalability and Business Continuity . Although ideas could still have been shared, perhaps towards a different audience, I decided it was time to stop, at least while I was holding this position. I left the blog online though and it still attracts 3000 hits a month as of August 2010, something that slightly worries me as the material will invariably become obsolete. If you read those lines, please note  I was working on or on older 10g releases.
