Problem summary
**************************************************************** * USERS AFFECTED: CICS users of APAR PK44963 (PTF UK28818). * **************************************************************** * PROBLEM DESCRIPTION: DFHDS0002 A severe error (code X'0204') * * has occurred in module DFHDSTCB. * **************************************************************** * RECOMMENDATION: * **************************************************************** PTF UK28818 changed DFHAPLI1 in refstep.kernel_error_abend_logic to set eis_program_mode to '0000'X after a task running on an L8 TCB has been set to UNCLEAN following an abend in the task. This was to ensure that the task did not attempt to switch back to the L8 TCB following the abend but continued to run on the QR TCB. However, as the task had been running on the L8 TCB, flag eis_abterm_allowed_switch was still on after switching to the QR TCB. This is invalid and if the task is suspended whilst running with ABTERM_ALLOWED(YES), "MSGDFHDS0002 A severe error (code X'0204') has occurred in module DFHDSTCB" is issued. As the L8 TCB was still available, it was not appropriate to switch to the QR TCB and the task should have continued to run on the L8 TCB. Additional keywords: DS0002 threadsafe cicsapi
Problem conclusion
UK28818 UK28819 UK30988 UK31566 DFHAPLI1 has been changed to turn off eis_abterm_allowed_switch after the task has been set to UNCLEAN and eis_program_mode has been set to '0000'X if the TCB is no longer available. If the TCB is still available, eis_program_mode and eis_abterm_allowed_switch are not altered.
