Please verify that in the TUNSSP00 Parm member, DB2HVEXT=YES & DB2HVe EXT=DB2E1.

It could be that these CA 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 CA MAT tries to connect to this moved DB2 Subsystem that one is testing with.

If these are not the symptoms, please open a new case through CA Support Online. Please provide CA Support with the S0C4 captured as an SVC dump, the complete MATUNER STC LOG, and please provide your maintenance level (last PTF applied, or run an SMP/E LISTMODS against the CA MAT CSI and send in the complete job output).
