RMAN Cross check Commands
Crosscheck is needed when an archivelog or file is manually removed i.e., not deleted by RMAN. This command ensures the data about backups in recovery catalog or controlfile is synchronized with corresponding data on disk
The crosscheck command does not delete any file that is unable to find out, but updates their repository records to expired
Use the crosscheck command to synchronize the physical reality of backups and copies with their logical records in the RMAN repository
For example
RMAN> crosscheck backupset 326;
You will get O/P as backup piece found it to be available, which confirms that the backup files exist and are usable.
