PH43379: TRANSACTION MAY BE INCORRECTLY REMOVED FROM CPSM WORKLOAD ON WLM GROUP INSTALL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You move a transaction from one TRANGRP to a new TRANGRP. Each
  transaction group is associated with a WLMDEF, and those WLMDEFs
  associated with a single WLM Group.
  
  
  When you install the WLM Group, you find that the transaction
  you moved from one tran group to another is completely removed
  from the workload. A EYUWM0443I message is issued indicating the
  transaction is being removed from both tran groups, rather than
  removed from one and added to the new one.
  

Local fix

• Install the WLM Group a second time.

  ****************************************************************
  A previously installed WLM group is altered, such that
  transaction groups associated are changed to move a transaction
  between these groups. When this WLM group is installed again
  after this change, moved transactions may be incorrectly
  discarded from the transaction group they were moved to, with
  message EYUWM0443I, e.g. :
  EYUWM0443I I date time applid Dynamic transaction (tranname)
  discarded from transaction group (trangrpid) in
  CICSplex (context) for workload (workloadid).
  
  This is due to processing in EYU0WMWI, which handles the
  install, installing the transaction while processing the TRANGRP
  it was removed from and removing it from the incoming list. As
  such, when the later TRANGRP is processed, it is identified as
  already being installed, but as its no longer on the incoming
  list, it is discarded when WMWI reconciles the objects.
  

Problem conclusion

• Install processing for WLM Groups, EYU0WMWI, has been corrected
  to re-add the dynamic transaction back to the incoming list if
  the transaction group it references has yet to have been
  processed.
