PI90027: CPSM CMAS EYUDREP SYNCHRONIZATION DIAGNOSTIC IMPROVEMENTS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In a CPSM environment, each CICSPlex has a designated MP
  ( Maintenance Point ) CMAS. All changes to the CICSPlex are
  made through this MP CMAS, and other CMASes managing the
  CICSPlex receive notification of those changes by way of
  MPSYNCCR (Maintenance Point Synchronization) records.
  .
  The MP CMAS keeps those changes for a period of time, but
  eventually must delete old change records, under the assumption
  that all the other CMASes managing the CICSPlex have received
  them by then. At the current time, there are no externalized
  messages indicating which MPSYNCCR records were deleted.
  .
  In order to improve serviceability, new diagnostic messages are
  being introduced to provide information about the deleted
  MPSYNCCR when that process occurs.

  *                      the DREP (data repository), which makes *
  *                      it hard for problem diagnosis.          *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes must be restarted. Note     *
  *                 that the restarts do not need to occur at    *
  *                 the same time.                               *
  ****************************************************************
  MP CMAS uses MPSYNCCR records to synchronize the resource
  definitions between CMASes to ensure that the resource
  definitions between CMASes are exactly the same. However, the
  CMAS periodically cleans up the old MPSYNCCR. If no records show
  when these records were deleted, it is not convenient to locate
  the problem when the data between CMAS is inconsistent.
  

Problem conclusion

• When CMAS deletes the MPSYNCCR record, the deleted record is
  printed in the trace of the CPSM. If there are multiple records
  deleted, only the first and last ones are printed.
