EXPIRED and AVAILABLE Status
You can view the status of backup sets and copies recorded in the RMAN repository through LIST,
vs views, or recovery catalog views (if you use RMAN with a catalog). Table 2-4 describes the
meaning of each status.
The crosscheck command only processes files created on the same device type as the channels
used for the crosscheck. The crosscheck command checks only objects marked available or
expired in the repository by examining the files on disk for disk channels or by querying the media
manager for sbc channels.
The CROSSCHECK command only processes files created on the same device type as the
channels used for the crosscheck. The CROSSCHECK command checks only objects marked
AVAILABLE or EXPIRED in the repository by examining the files on disk for DISK channels or by
querying the media manager for sbt channels.

CROSSCHECK
Purpose
