Oracle Database 11g: SQL Tuning Workshop Release 2

Course Description & Objectives:

This course assists database developers, DBAs and SQL developers to identify and tune inefficient SQL statements. Learn investigative methods to reveal varying levels of detail about how the Oracle database executes the SQL statement; this helps you determine the root causes of the inefficient SQL statements.

Students learn to:

Use Oracle tools to identify inefficient SQL statements.
Use Automatic SQL Tuning.
Use Real Time SQL monitoring.
Write more efficient SQL statements.
Monitor and trace high load SQL statements.
Manage optimizer statistics on database objects.

Interpret execution plans, and the different ways in which data can be accessed.

Duration:

24 hours.

Gaining skills:

Use the Oracle Database tuning methodology appropriate to the available tools
Utilize database advisors to proactively tune an Oracle Database Instance
Use the tools based on the Automatic Workload Repository to tune the database
Diagnose and tune common SQL related performance problems
Diagnose and tune common Instance related performance problems
Use Enterprise Manager performance-related pages to monitor an Oracle Database
