Explanation:
When implementing an RMAN-based backup strategy, you can use RMAN more effectively if you understand the more common options available to you. Many of these can be set in the RMAN environment on a persistent basis, so that you do not have to specify the same options every time you issue a command.To simplify ongoing use of RMAN for backup and recovery, the RMAN lets you set a number of persistent configuration settings for each target database. These settings control many aspects of RMAN’s behavior when working with that database, such as backup retention policy, default destinations for backups to tape or disk, default backup device type (tape or disk), and so on.
