The three fundamental steps of SQL Tuning are: 1) Diagnostics Collection; 2) Root Cause Analysis (RCA); and 3) Remediation. This introductory session on SQL Tuning is for novice DBAs and Developers that are required to investigate a piece of an application performing poorly.
On this session participants will learn about producing a SQL Trace then a summary TKPROF report. A sample TKPROF is navigated with the audience, where the trivial and the no so trivial is exposed and explain. Execution Plans are also navigated and explained, so participants can later untangle complex Execution Plans and start diagnosing SQL performing badly.
This session encourages participants to ask all kind of questions that could be potential road-blocks for deeper understanding of how to address a SQL performing poorly.
