Oracle Database 11g: Performance Tuning DBA

Overview

This Oracle Database 11g Performance Tuning training starts with an unknown database that requires tuning. You’ll then learn the steps a DBA performs to identify problem areas, diagnose common problems and fix them.

Learn To:

  • Describe Oracle tuning methodology.
  • Use Oracle supplied tools for monitoring and diagnosing SQL and Instance tuning issues.
  • Use database advisors to correct performance problems proactively.
  • Identify problem SQL statements & tune SQL performance problems.
  • Monitor the Instance Performance using Enterprise Manager.
  • Tune instance components, primarily using Instance parameters.

Benefits to You

Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling smooth and rapid consolidation within your Datacenter.

Course Methodology

The methodology used in the practices is primarily reactive. After configuring monitoring tools and reviewing the available reports, you’ll be presented with the Oracle architecture based on the SQL statement processing of SELECT and DML.

SQL Tuning

The SQL tuning section assumes that the DBA has little or no ability to change the code. The DBA will influence the SQL performance with available tools, and will be introduced to various methods of identifying the SQL statements that require tuning (as well as the diagnostic tools needed to find ways to change the performance).

This will include the use of statistics, outlines and profiles to influence the optimizer, adding and rebuilding indexes and using the SQL Advisors. This course introduces the DB Replay and SQL Performance Analyzer tools to help you test and minimize the impact of change.

Instance Tuning

Instance tuning uses the same general method of observing a problem, diagnosing the problem and implementing a solution. The instance tuning lessons cover the details of major tunable components and describe how you can influence the instance behavior. For each lesson, we will examine the relevant components of the architecture.

The class only discusses the architecture to the level required to understand the symptoms and solutions. More detailed explanations are left to other courses, reference material and Oracle documentation.
