Error description

  • You are running CTS 4.2 RSU1206.  We have a AOR region that
    connects to 3 FOR's (files split amongst the three regions) not
    using RLS.   Your region was going in and out of SOS and a XXXX
    task was purged.  That resulted  in this first abend:
    +DFHAP0001 An abend (code ---/AZI9) has occurred at offset
    X'0996' in module DFHCRIU.
    This resulted in a loop of the following abend:
    DFHAP0001 An abend (code 0C4/AKEA) has occurred at offset
    X'031A' in module DFHCRIU.

    ****************************************************************
    An application running in a CICS AOR function ships requests to
    multiple FOR regions connected by IRC links. The remote files on
    the FOR regions are defined as recoverable. The application
    issues an EXEC CICS SYNCPOINT request and DFHCRIU sends a
    PERFORM_PREPARE to the first region. The associated task is
    suspended on IRLINK while it awaits a response to the
    SYNCPOINT.
    During the suspend the task is FORCEPURGEd resulting in an ABEND
    AZI9, dfhcriu_Recovery_Routine is driven and issues an exception
    trace entry, AP X'0D82', criu_module_recovery, followed by
    message DFHAP0001. The recovery routine obtains the TCA pointer
    for the task but does not set R12 to address the TCA before
    returning to mainline code. Mainline code expects R12 to address
    the TCA, and the first attempt to process an operation involving
    the TCA causes a program exception, and the recovery routine to
    be driven again. The recovery routine is called repeatedly in a
    loop, each time it runs writing exception trace and issuing
    message DFHAP0001.

Problem conclusion

  • The DFHCRIU recovery routine has been changed to set R12 to the
    TCA address.
