We provide several alternatives for recovering corrupted IMS databases:
Automatic Backward Recovery
Forward Recovery
To use Forward recovery, you must enable it. Backward Recovery is enabled by default. We recommend that you have both enabled,
as together they provide the best coverage.
IMS Database Forward Recovery Describes IMS database recovery using database image copies and forward recovery log files to restore the most recent database
updates.
TLOG Files Describes the transaction log files (TLOGs) used in IMS database Backward and Forward recovery.
