Because of some logistical reasons we do not have a specific Parallel Execution booth on the demo grounds at OpenWorld this year. Instead the PX development team will be at the SQL Analytics and Analytic Views booth on Oct 27, Tue, 2pm-5pm and Oct 28, Wed, 10:15am-1pm. If you have any questions about PX or if you just want to chat with PX developers find us at that booth. You can also put your questions beforehand as comments here and come talk about them at the booth.
Other than that my session on how to make people happy in a DW will be at Moscone South 307 on Oct 27, Tue, 12:15pm. Come and join us to talk about how the Oracle Database is nice to all of its users and treats them well.
