How to Register or Catalog Backups, Archive logs, data file copy, FRA...etc

When you backup using RMAN all backups  will be registered with catalog. If you have taken backup without catalog and you can also register manually.

Backup pieces copied manually to different location to catalog backup piece run below command.
RMAN> CATALOG BACKUPPIECE /oracle/backup/DB1_1978087_6446005710.bkp' ;

In case if you have taken backup using o/s command and to catalog a datafile copy use below command.
RMAN> CATALOG DATAFILECOPY '/oracle/backup/employee01.bak' LEVEL 0;

In case, archive log location full and you have moved backups to different location using o/s command then you can register the archive logs using below command

RMAN> CATALOG ARCHIVELOG ‘/oracle/backup2/db1_arch_99089_0876589.arc'
If you are using Flash recovery area and want to catalog all files in the FRA use below command.
RMAN> CATALOG recovery area;

This command will prompt to confirm that you want the found files to be cataloged. If you do not want to prompt use “noprompt” clause.
RMAN> CATALOG recovery area noprompt;

If you want to catalog only files Start with specific name or belongs to specific SID (db1) use below command
RMAN> CATALOG START WITH '/oracle/backup/db1'

If you run CROSSCHECK, it will go through the files that match criteria and will be marked as available, and files not found will be marked as EXPIRED.

RMAN> CROSSCHECK BACKUP ;
If you want to DELETE EXPIRED backups you can use below command, note that EXPIRED copy will no longer appear in RMAN. You have to be extra cautious to delete backups.

RMAN> DELETE EXPIRED BACKUP ;

If you find extra copies and want to delete those extra copies use DELETE BACKUPPIECE command:
RMAN> DELETE BACKUPPIECE 4555;
Hope this helps managing your backups taken outside of RMAN recovery catalog .

Thanks & Regards
