RMAN-06059: expected archived log not found, loss of archived log

This error occurs when we try to backup using RMAN:

RMAN> backup database plus archivelog;

Cause: The archived logs are either deleted or moved another location on disk and the control file could not find the archived logs.

Solution: You must update RMAN’s repository to reflect that archived redo log files have been either
physically deleted or moved to another location on disk.

1. If the the archived logs are removed from disk use the CROSSCHECK command to inform RMAN:

   RMAN> crosscheck archivelog all;
   --Now the backup command and it will work.
   RMAN> backup database plus archivelog;

2. If the archived logs are still on the disk but on different location use CATALOG command to update RMAN repository with the new location:

   RMAN> catalog start with '/DR-RBKP/Friday/oldarchive'
