Environment

Release:
Component: MATUNE

Resolution

Verify that in the TUNSSP00 Parm member, DB2HVEXT=YES & DB2HVE EXT=DB2E1.

It could be that these MAT R9 S0C4 abends are caused by the DB2 Group moving an already active DB2 Subsystem from one z/OS LPAR to another z/OS LPAR without an IPL. The abends occurred when MAT tries to connect to this moved DB2 Subsystem that one is testing with.
