This course takes the database administrator beyond the basic tasks covered in the first workshop. You will begin by gaining a much deeper understanding of possibly the most important job of a DBA: backup and recovery. You will learn, in detail, the concepts and architecture that support backup and recovery, along with the steps of how to carry it out in various ways and situations, including how to define and test your own backup and recovery scenarios.

You will learn how to manage memory effectively and how to execute performance evaluations and tuning tasks using some of the advisors. You will also cover all types of flashback technologies, scheduling jobs inside and outside of the database, and controlling system resource usage.

What You'll Learn

• Back up and recover a database with RMAN (command-line and Enterprise Manager)
• Use flashback technology to view past states of data and to revert either objects or the entire database back to a past state
• Use an appropriate and flexible memory configuration for your database
• Burdensome database sessions and poorly performing SQL
• Configure the Oracle database for optimal recovery
• Appropriately configure the database instance so that resources are allocated among sessions and tasks
• Schedule jobs to run inside or outside of the database
• Use compression to optimize database storage and duplicate a database

Who Needs to Attend

Support engineers, technical consultants, and database and technical administrators

Prerequisites

• Working knowledge of SQL and how to use PL/SQL packages
