Presentation Title

Session #1: Exadata Performance Method

Session #2: More Complex Performance Issues I've Seen


Session 1: Exadata Performance Method — In this presentation, Tanel will take you through the sequence of steps he uses for determining whether a workload is getting the most out of the Exadata-specific performance features such as the Smart Scans and its related offloading options. This presentation does not attempt (and doesn't need) to reinvent the wheel of general performance optimization methods, such as Method-R, but will present just the Exadata-specific extensions to such methods. In addition to case studies, Tanel will present some scripts and tools he uses for his Exadata performance work.

Session 2: More Complex Performance Issues I've Seen — Following last year's "Most Complex Performance Issues" presentation, this year, Tanel will cover multiple complex performance problems he has worked on in the last year. We will look into a few different performance issues involving multiple components such as the database, OS issues and bugs. In all of the cases, the initial symptoms pointed to something completely different from the actual root cause, and a systematic troubleshooting approach had to be used to find out the real cause of the problems.
