The most important job for an Oracle database administrator (DBA) is the backup and recovery of Oracle databases.
In the first course in this series, you learned what could happen when you do not take this role to heart.
As a DBA, you can almost get away with a poorly performing database, as long as the data within the database is correct.
After all, poor performance can be eliminated with tuning, Oracle Sql Tuning.
But if the data is not available or cannot be recovered, your ability to restore the original state will be in jeopardy.
Oracle contains a new utility called Recovery Manager, or RMAN, to manage the backup, restoration, and recovery of Oracle database files. If you
are managing multiple databases, RMAN is the tool for you. This module introduces Recovery Manager and its components.
By the end of this module, you will be able to:
Discuss the purpose and features of Oracle Recovery Manager
Review the basic components of RMAN
Discuss the preparation involved in using RMAN
Discuss the role of Backup Manager as a graphical user interface (GUI) tool for backup and recovery
Discuss how backup sets are used within Recovery Manager
Discuss the concept of image copies
Discuss the role of the recovery catalog
Demonstrate how to create a recovery catalog
For more detailed information, refer to the Oracle Server Backup and Recovery documentation. You can find this on your Oracle release CDs. This
documentation can also be found online at the Oracle Web site refer to the Resources page for additional information. Several third-party books on
the topic can also provide practical examples and can be found on the Resources page. In the next lesson, you will learn the basic features of
Oracle Recovery Manager.
