Why Is The Catalog Optional? |
|
Answer» Catalog is optional because RMAN manages BACKUP and recovery operations and it REQUIRES a place to store necessary INFORMATION about the database. RMAN always stores this information in the target database control file. You can also store the RMAN metadata in a recovery catalog schema contained in a separate database. The recovery catalog schema must be STORED in a database other than the target database.
