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.

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.
