Oracle Database 12c: Performance Management and Tuning NEW

Duration: 5 Days

What you will learnIn the Oracle Database 12c: Performance Management and Tuning course, learn about the performance analysis andtuning tasks expected of a DBA: proactive management through built-in performance analysis features and tools,diagnosis and tuning of the Oracle Database instance components, and diagnosis and tuning of SQL-relatedperformance issues.

Learn To:Use the Oracle tuning methodology.Use Oracle-supplied tools for monitoring and diagnosing SQL and instance performance issues.Use database advisors to proactively correct performance problems.Identify and tune problem SQL statements.Monitor instance performance by using Enterprise Manager.Tune instance components.

Benefits To You:The DBA will analyze the SQL performance with available tools. The DBA will be introduced to various methods ofidentifying the SQL statements that require tuning and the diagnostic tools used to find ways to improve performance.This will include the use of statistics, profiles to influence the optimizer, and using the SQL Advisors.

Maintain SQL PerformanceA major task of DBAs is to maintain SQL performance across changes. This course introduces Database Replay andSQL Performance Analyzer which help the DBA test and minimize the impact of change.

Influence Instance BehaviorInstance tuning uses the same general method of observing a problem, diagnosing the problem, and implementing asolution. The instance tuning lessons cover the details of major tunable components and describe how you caninfluence the instance behavior. For each lesson, we will examine the relevant components of the architecture.The course only discusses the architecture to the level required to understand the symptoms and solutions. Moredetailed explanations are left to other courses, reference material, and the Oracle documentation.
