• Closed as program error.

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.

  ****************************************************************
  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.
