How to restore control file using Fast Recovery Area

If controlfile autobackup is enabled and the default location of db_recovery_file_dest parameter is fast recovery area(FRA), you can restore the controlfile using the following commands.

$ rman target /
RMAN> startup nomount;
RMAN> restore controlfile from autobackup;

And Finally RMAN restores the control files to the location defined by your control_files initialization parameter.

If controlfile autobackup is not enabled, we can restore the controlfile using the following SQL commands:

$ rman target /
RMAN> startup nomount;
RMAN> restore controlfile from
'+FRA/proddb/backupset/2022_09_25/o6_mf_dfmmf_90cf0z_.bkp';
