Oracle DBA manages the performance of database and security

Oracle DBA is an intensive designed to provide Oracle professionals with an in-depth understanding of the DBA features of Oracle. Broad in scope, this course covers all of the Oracle Database Administration topics including SGA instance management, file & tablespace management, user administration & security and table & index management. 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.

Features:

·         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.

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.

·         Manage space to optimize database storage so you can respond to growing space requirements.

·         Monitor and manage major database components, including memory, performance and resources.

·         Secure the availability of your database through appropriate backup and recovery strategies.

·         Automate DBA tasks with the Scheduler.

Backup & Recovery: The concepts and architecture that support backup and recovery, along with the steps required to execute it in various ways and situations, are covered in detail. You'll learn how to define and test your own backup and recovery scenarios.

Manage Memory Effectively: You'll also learn how to manage memory effectively, as well as how to perform some performance evaluation and tuning tasks. Instructors will review all types of flashback technologies, scheduling jobs inside and outside of the database and controlling system resource usage.
