Question & Answer
Do you know what could cause my CICS region to receive message DFHDS0002 A severe error (code X'0204') has occurred in module DFHDSTCB? I got this message while I trying to purge a task. I'm using Strobe from Compuware to track DSAT_CHANGE_MODE and wonder if it is possible that it could be causing this problem.
Strobe could be causing the DFHDS0002 with severe error X'0204' in DFHDSTCB. Compuware provided some Strobe fixes that address the problem. For Strobe 5.1 the fix is SBB177A and for Strobe 5.2 the fix is SBC018A.
This problem and the fixes only apply to CICS TS 4.2 and higher.
