Upcoming events: INOUG Oracle Training Day!

The Indiana Oracle User Group (INOUG) have been kind enough to ask me to present an all day Optimizer workshop at their annual training day on July 26th at Eli Lilly & Co. The workshop will consist of four 90 minute session and will explain the fundamentals of the cost based Optimizer and the statistics that feed it, as well as providing a methodology for diagnosing and resolving SQL execution performance problems.

The workshop begins with an in-depth look at statistics and statistics maintenance, a challenge all DBAs must face in order to prevent suboptimal execution plans. It continues with a detailed explanation on how to interpret an execution plan. Each aspect of an execution plan will be examined, from cardinality estimates to parallel execution, and you will learn what information you should be gleam from the plan and how it affects the execution performance of a SQL statement. After lunch the workshop focuses on the process of analyzing and resolving the most common SQL execution performance problems including poor cardinality estimations, bind peeking issues, selecting the wrong access method and much, much more.

You can register for the event here. I hope you can join us!
