Using a Disciplined Approach to Problem Diagnosis
Performance is poor, user sessions are 'hanging', management is wanting a diagnosis NOW! What do you do? Use the G2 method? Gather everyone in a conference room for a brainstorming session? Flush the shared pool, analyze everything and change a couple of database parameters? If it works (or fails), do you know why? More importantly, when performance is poor next week, can you repeat your actions with the same result? If a diagnosis process is not explainable and repeatable, it is undisciplined and unreliable. Diagnostic Routines bring discipline to the troubleshooting and optimization process. This presentation covers some of the common undisciplined approaches, the foundations of and techniques for developing disciplined processes, and finishes with basic diagnostic routines and root cause analysis for Oracle sessions. The topics and methods are designed to enable the attendee to develop methods that are specific to their system, application and situation.
