Error description

  • When we entered /STO REG ABDUMP command while WFI MPP region was
    waiting for message on SUBQ, behavior of ESTAE exit handling was
    different between IMS V9 and IMS V11.
    Under IMS V9, user ESTAE exit was not called for ABENDU0474.
    But under IMS V11, user ESTAE exit was called for ABENDU0474.
    This difference came from SAP XM flag setting when WFI MPP
    region waited under WFITEST in DFSFXC30.
    In IMS V9, SAP XM flag was off and MPP region was killed via
    CALLRTM in DFSASK00.
    In IMS V11, SAP XM flag SAPX1LUM was on and ECB was posted
    instead of CALLRTM.
    Problem happens for WFI MPP with APPC.

    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    Module DFSSLUM0 resets the LUM XM flag before issuing
    APPC confirm call if the synclevel is confirm.  After
    the client replies confirmed then DFSSLUM0 sets the
    LUM XM flag in the SAP.  If the LUM XM flag was not
    on before the APPC confirm call then it gets set after
    the APPC confirm call but will not be reset after the
    DFSLUMIF send service.
    
    Note that the LUM XM flag in the SAP will be reset when
    the application terminates. WFI transactions are
    normally not terminating so the LUM XM flag in the SAP
    will be on until the operator issues /STO REG command.
    At this time the dependent region abends with ABENDU0474.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    Modules DFSSLUM0 & DFSYSLM0 have been modified to save the XM
    flags in SAP when it resets the LUM XM flag and then check if
    the LUM XM flag was on before setting the LUM XM flag.
