File control recovery program exits XFCBFAIL, XFCBOUT, XFCBOVER, and XFCLDEL
CICS® provides four global user exits that you can use in connection with file control recovery operations.
These are:
- XFCBFAIL
- Invoked when an error occurs during backout.
- XFCBOUT
- Invoked when CICS is about to back out a file update.
- XFCBOVER
- Invoked when CICS is about to skip unit-of-work (UOW) backout because a batch program has overridden RLS retained lock protection and opened a data set for batch processing.
- XFCLDEL
- Invoked when backing out a write to a BDAM or a VSAM ESDS data set.
