Issue:

I implemented maintenance for CA DADS Plus for CICS CTS 5.4 It appears that DADS is now allocating the load library in the MDFYRPL as exclusive or open for write. The PTFS applied were RO53206, RO91358  and RO96817.

I am getting an abend with the following messages.

Environment:
Z/OSCICS
Cause:

After some investigation, I believe the application programmer tried to use the Module Override function to cause the ACF2 abend and allocating the load library as exclusive to the CICS region. The user has never had done this testing before. I had just implemented the maintenance and I thought the new maintenance caused the problem.

Resolution:

The client setup security for the Module Override MENU function transaction DAM0.
The module override menu transaction is DAM0.
