Archived Log Deletion is a feature for Oracle database server to automatically delete the archived logs that are older than the specific period.
Archived Log Deletion feature applies Oracle Recovery Manager (RMAN) to work. After a backup job, RMAN will automatically match and remove the archived logs that are older than the specific days. For example, the period limit is set to 3 days, then after a backup, RMAN will automatically match and remove the archived logs older than 3 days. Please refer to the following URL for further details about RMAN: http://www.oracle.com/technetwork/database/features/availability/rman-overview-096633.html
Please kindly note that if you find "[Delete archived logs] specification does not match any archived log in the repository" sentence in the backup log, it means there is no archived logs older than the setting specific period. For example, the period limit is set to 3 days, "[Delete archived logs]specification does not match any archived log in the repository" means there is no archived logs older than 3 days, so no archived log will be removed.
