As DBAs, we know that few tools are as critical to SQL optimization as the SQL execution plan. The ability to read and understand an execution plan is critical to evaluating and optimizing SQL performance. Unfortunately, complex plans are daunting and can be difficult to understand.
Fortunately, Karen Morton will walk you through a relatively short and easy to follow set of guidelines for how to read an execution plan and how to make sense of the operations and statistics (both estimated and actual) the plan output provides. Learn how to leverage one of the most important tools at your disposal.
Topics covered in this webinar include:
How to read an execution plan, and how various plan operations work
How to use the plan to pinpoint performance problems
Tools to accelerate you analysis of execution plan data
*Please note that Karen uses Oracle SQL database in her examples.
