RE: Recovery Catalog
|
| Recovery catalog is a repository of metadata that is available in the control file of the target database. Whenver we take backups using RMAN, the copy of the backup is placed in the control file in the form of reusable records and as well as in the recovery catalog in the form of tables. So that while taking recovery also, these table info is useful to apply the backup data. |
