CICS® VR
batch backout processing is started by running the DWWBACK program.
The DWWBACK batch backout program can be started in one of the following
ways:
- Automatically by CICS VR when a batch job encounters an abend.
- Manually by creating and submitting a batch job that starts the DWWBACK
program.
Note: To use the CICS VR batch backout utility, undo logging must enabled
for the VSAM spheres, along with some other additional configuration. See
Setting up CICS VR VSAM batch logging, for further information on setting
up CICS VR
VSAM batch logging.
CICS VR
batch backout supports KSDS, ESDS, RRDS, and VRRDS VSAM spheres.
The following sections describe the manual and automatic execution of CICS VR
batch backout.
