The RMAN environment consists of the utilities and databases that play a role in backing up your data. At a minimum, the environment for RMAN must include the following:
● The target database to be backed up
● The RMAN client, which interprets backup and recovery commands, directs server sessions to execute those commands, and records your backup and recovery activity in the target database control file.
Some environments will also use these optional components:
● A flash recovery area, a disk location in which the database can store and manage files related to backup and recovery
● Media management software, required for RMAN to interface with backup devices such as tape drives
● A recovery catalog database, a separate database schema used to record RMAN activity against one or more target databases
The following diagram illustrates these components:
