Maria Colgan
Master Product Manager

Oracle Open World, the largest gathering of Oracle customers, partners, developers, and technology enthusiasts will happen October 2-6 in San Francisco. Of course the Optimizer development group will be there and you will have multiple opportunities to meet the team, in one of our technical sessions, or at the Oracle demogrounds.

This year the Optimizer team has 3 technical sessions;

  • Monday, October 3rd at 12:30pm  our hands on lab, Oracle Optimizer: Prevent Suboptimal Execution Plans
    Session 29380 at the Marriott Marquis - Salon 12 / 13
    In this hands on lab you will get an opportunity to solve 4 SQL tuning problems either on your own or with the help of the Optimizer development team. The problems will include scenario like, why was my index not selected, why statistics were ignored, and many more.
  • Wednesday, October 5th at 10:15am Oracle Optimizer: Best Practices for Managing Optimizer Statistics
    Session 13961 at Moscone South - room 103
    In this session we will discuss the features introduced in Oracle Database 11g to improve the quality and efficiency of statistics-gathering as well as strategies for managing statistics in various database environments.
  • Thursday, October 6th at 12 noon Oracle Optimizer: Tips for Preventing Suboptimal Execution Plans
    Session 14069 at Moscone South - room 104
    This session is a continuation from a session we did last year called Top Tips for getting optimal SQL execution every time. This year we answers questions like why an index wasn't used, why partition eliminations did not occur, why statistics were ignored, and many more. With clear how-to examples, you will learn to identify and quickly resolve these issues without the need for optimizer hints or initialization parameters.

If you have some burning Optimizer or statistics related questions, you can ask them at the Optimizer demo booth in the Database area of the demogrounds. Members of the Optimizer development team will be there Monday to Wednesday from 9:45 am until 5:30pm. The full searchable OOW catalog is on-line, or you can browse the speakers by name. So start planning your trip today!
