Changing the action of Z Abend Investigator when invoked via the CICS XDUREQ global user exit (CICSNOA)

The CICSNOA setting in the HFZOPTLM configuration-options module can be used to change the action of Z Abend Investigator when invoked via the CICS® XDUREQ global user exit, and should only be considered if an installation requires special handling of CICS transaction abends as outlined in the following.

When a prior CICS exit program has specified a return code UERCBYP (suppress transaction dump), then Z Abend Investigator by default continues to perform analysis. This behavior is equivalent to the way in which non-CICS abends are handled by the MVS™ pre-dump exit, HFZXDCAP.

When using the CICSNOA setting, a prior XDUREQ exit program return code of UERCBYP stops Z Abend Investigator from performing analysis.
