Lesson 1
Oracle Recovery Manager overview
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. But if the data is not
available or recoverable, your position may be in jeopardy.
Recovery ManagerOracle8 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.
