Control File Backups

The control file contains metadata about the physical structure of the database including the location of all files, the current database state etc. Each control file is associated with only one database. The control file backups are used for creating standby databases from the CommCell Console. Standby databases are used during database recovery.

Use control file backups to create standby databases from the CommCell Console. Standby databases are used during database recovery.
