Files

CICS® file control is presented with the log records of all the recoverable files that have to be backed out.

File control performs the following processing:

Restores the before-images of updated records
Restores deleted records
Removes new records added by the unit of work

If backout fails for any file-control-managed resources, file control invokes backout failure support before the unit of work is marked as backout-failed. See Backout-failed recovery.
