Error description
After an abend in a Task related user exit program ( TRUE ) defined as OPENAPI, CICS issues message: . DFHDS0002 A severe error (code X'0204') has occurred in module DFHDSTCB. . In this case, the TRUE is EZACIC01 which does not have recovery specified. DFHERM 's recovery routine then gets control and and attempts to put out message DFHAP0707. However, since the TRUE was executing as OPENAPI, it was executing on an L8 TCB with ABTERM_ALLOWED(YES) when the abend was issued. During processing of the DFHAP0707 message, the task is suspended on the DUSYDUMP lock. At suspend time, the CICS Dispatcher finds that the task is still running ABTERM_ALLOWED and issues the DSTCB_INVALID_ABTERM or DFHDS0002 '0204'. . It appears that any abend in an OPENAPI TRUE (other than the DB2 TRUE) will be followed by DFHDS0002 0204 if it suspends for any reason while putting out the DFHAP0707 message. .

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: DFHDS0002 issued when an OPENAPI TRUE * * abended. * **************************************************************** * RECOMMENDATION: * **************************************************************** In the reported problem, a TRUE program was running OPENAPI which caused it to run on an L8 TCB. The TRUE abended and DFHERM's recovery routine received control and attempted to issue message DFHAP0707 under the L8 TCB. During this process, the task was suspended on the DUSYSDMP lock. The Dispatcher detected this suspend and also the non valid TASK_STATE of RUNNING_ABTERM_ALLOWED. As a consequence, the DFHDS0002 message with error code X'0204' was issued. Keywords: msgDFHDS0002 DS0002 msgDFHAP0707 AP0707 msgDFHAP0708 AP0708 AKEJ
Problem conclusion
DFHERM has been modified and will switch to the QR TCB when issuing message DFHAP0707 or DFHAP0708 as part of recovery processing for a TRUE and on return restore the original TCB mode.
