Course Outline:
SQL Statement Tuning
- Oracle RDBMS Architecture overview
- Understanding/Reading/Interpreting Explain Plans
- Understanding the Rule-based Optimizer
- Understanding the Cost-based Optimizer
- Working with Hints
SQL Tuning Tools
- Tuning Tool Review: Statspack, Events, Tracing/Tkprof
- Profiling and tuning PL/SQL
- Finding Problem SQL using v$ information
Detailed Overview:
The course starts out with a complete overview of the Oracle architecture, so students can get an understanding how their SQL and applications can take advantage of the computing environment. It then moves to a discussion on the differences of the various Explain Plan steps such as Merge-Join and Nested-Loop, and when is it best to use each. Dan goes into considerable detail, with SQL examples, on how the optimizers (both rule and cost) make their decisions. Participants will work with a variety of SQL statements, reviewing explain plans and making changes to make these SQL statements perform better. They will also experience how to monitor their application environment, and see how to find problem SQL in their applications.

This workshop includes a section on monitoring Oracle RDBMS and SQL via the v$ tables and TOAD and is packed full of scripts to discover a variety of issues.

The programme is perfect for developers who need to know more on how Oracle works and how to get their SQL to perform better. This course is also good for those who are light on SQL tuning or perhaps are new to the Oracle RDBMS.

The course utilizes a variety of current tools. Participants will have the opportunity to learn more about TOAD and SQL Developer, as well as the Oracle tools like SQL*Plus, TKProf, and Stats Pack.
