    * PROBLEM DESCRIPTION: IMS needs to know when a syncpoint was  *
    *                      issued from a CICS program that was     *
    *                      invoked via a DPL request.              *

    * RECOMMENDATION:                                              *
    ****************************************************************
    To prevent a possible deadlock, IMS needs to know whether a
    syncpoint request was issued from a task that was DPLed to.
    Currently the PAPL request for a syncpoint gives no indication
    that the task was generated because of a DPL request.

Problem conclusion

  • DFHDBAT will set new bit PAPLSDPL to x'04' in flag PAPLCFLG if
    the syncpoint request is from a task that has been DPLed to.
    The CICS Transaction Server for z/OS V4R1, GC34-7014-00 CICS
    Data Areas, should be amended.
