How to suppress Abend-Aid dump processing for Database Management for Db2 for z/OS batch jobs and TSO sessions.

Resolution

It is recommended to suppress ABEND-AID intercepts within the DB2 tools so complete SYSMDUMP dump
datasets can be obtained to diagnose the problem if it occurs again.

For Batch processes add the following DD to the JCL:
//ABNLIGNR DD DUMMY SUPPRESS ABENDAID DUMPS

For Online processes:
Use TSO ALLOCATE command to allocate a DUMMY file to the ABNLIGNR DD

If the TSO session has ABNLIGNR already allocated, then a TSO FREE FILE('ABNLIGNR') command needs to be executed first.
Then follow with the TSO ALLOCATE DUMMY FILE('ABNLIGNR') command to allocate the DUMMY file.

Allocating ABNLIGNR to DUMMY will prevent Abend-Aid from intercepting the SYSMDUMP dump.
If you encounter the abend and are kicked out to the TSO READY prompt, press enter at that point to get the SYSMDUMP dataset written out.
