The first professional technical presentation I ever gave was on March 31, 2003. I had been a DBA for just less than 2 years. It was at an event called “SDC West Geek Fest”. It was an internal IBM event within Global Services where the technical folks delivering services got together to share technical expertise. The title was something along the lines of “10 ways to improve physical performance in Db2”. This was just after version 8.1 was released.
Corrected on 9/8/2017 to reflect correct syntax to eliminate just the one table.
