OSL - CPH - SFO. Starting on my route in a few hours. Really look forward to see tweeps and a bunch of people from the worldwide Oracle community. Lots of good presentations of course, but also bloggers' meetup, Oaktable world, RAC Attack, Anchor Steam, and more.

Last year was my first time at OOW. I made a write-up every day on my blog, but this year I will maximize, meaning it will be little time for blogging while being there. It is now less than four two one hours before I start on my trip OSL-SFO. Writing about what I plan to do seems like a great way to kill time. Also I’m doing some proactive jet-lag prevention research, may be staying up late will make the transition from CET to PT easier (or is it CEST and PST now?).

OOW has been great and I’m reaching the limit of how much information I can consume for a while. I’ll probably spend some weeks or months reading and understanding presentations. Time to go home and practice what I’ve learned. I’m not even going to try to report dutifully on every session today. Just say that I’ve been to Real-World Performance Questions and Answers, Oracle Database Optimizer: Tips for Preventing Suboptimal Execution Plans, Looking Under the Hood at…

Day four started well with Oracle Optimizer: Best Practices for Managing Optimizer Statistics presented by Maria Colgan. Then followed SQL Tuning Expert Roundtable with Jagan Athreya, Benoit Dageville, Tom Kyte and Graham Wood. These two presentations had a lot in common, correct statistics should be checked if plan is wrong, note correct, but not necessarily updated statistics. If an automatic routine for stats gathering cannot be found the metadata for the table and columns should be set…

Went to five presentations, two of them stood out. Doug Burn spoke about SQL plan management in 11g and I learned some new tricks. The material and the content was quite good, also I like these comments that may not be in the slides, e.g. he quoted Jonathan Lewis who said that if you have a narrow problem you should apply a narrow solution, an advice against changing a system wide parameter just because you have one SQL statement gone astray.

Went to the keynote and five presentations. Keynote was a lot of show, but not much to bring home. Two presentations regarding database migration assistant for unicode, and Real Application Testing were relevant, but so uninspiring and lacked the extra stuff that it was like attending someone reading from the manual. Not much of a take away there either. Also went to a presentation on PL/SQL - Divide and Conquer, modularizing your code. I had hoped to hear more from Bryn Llewellyn, Oracle, but…

First day at OOW 2011 started with interesting presentations arranged by IOUG, very usefull stuff and I have to read the presentations again to get all the details regarding Oracle on VMware, and deploying APEX with security in mind.

This year when I was on my way to MOW 2011 in Denmark, a few months after I started at Keystep, my manager called me and asked if I wanted to go to Oracle Open World. That has not happened before in any other job I’ve had and of course I said yes, so here I am in San Francisco. Arrived late Friday, and spent Saturday adjusting to new timezone and walk around. First observations: really nice city, want to bring my family and see more. Also lots of nice people, with some exceptions from…
