TSS9406E followed by DFHUS0002 0309 in DFHUSAD when using CA Top Secret

Question & Answer


Question

After implementing PASSTICKETS to my CICS Transaction Server for z/OS (CICSTS) region, why do I get a US0002 dump and the following messages in the CICS log?

You are using CA Top Secret from CA Technologies.

Answer

Apply CA Top Secret fix SO06885 to fix the TSS9406E and DFHUS0002 severe error code X'0309' in DFHUSAD.

To confirm that this fix will resolve your problem, you can enter IPCS command VERBX DFHPD700 'TR=2' (where "700" is for CICS TS 5.3) to display the CICS trace in the system dump. You should see the following trace exception:

 FE04 XSSA  *EXC* FUNCTION(DELETE_USER_SECURITY) 
                  RESPONSE(EXCEPTION)            
                  REASON()

Enter command VERBX DFHPD700 'KE=1' to display the Kernel stacks of the tasks that are receiving the DFHUS0002 error and you will see that they look like the following stack:

                      TAKE_SYSTEM_DUMP  

CICS is getting back an exception from CA Top Secret that is determined to be unknown.
