RDB/VMS RMU/ALTER UNCORRUPT — VMS RDB_4.0
Resets the area's corruption indication flag (FILID CORRUPT_FLG), thus allowing you to use the uncorrupted sections of a corrupted storage area. Storage areas are most often corrupted by attempting a VAX Rdb/VMS (not RdbALTER) rollback with one or more storage areas opened in BATCH UPDATE.
