PH60089: CMAS ISOLATION POSSIBLE AFTER APPLYING FIX FOR PH48455. EYUCP0205S AND EYUCP0011E REPORT REPOSITORY SYNC FAILED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are restarting many of your CMASs simultaneously after
  running the EYU9XDUT utility against their EYUDREP data sets.
  You receive messages indicating the repository resync process
  has failed, and that one or more of your CMASs are being
  isolated. Some of the messages in the CMAS job output related to
  this event may include the following (not all messages in each
  CMAS)
  
  EYUCP0033I cmasname Disconnect requested for CMAS cmasname2.
            Reason: CMAS isolated.
  EYUCP0207E CICSplex plexname on CMAS cmasname cannot be
            redefined as MASes are active on CMAS cmasname
  EYUCP0205S plexname Repository Synchronization with CMAS
            cmasname failed.
  EYUCP0011E cmasname Repository synchronization failed for one or
            more CICSplexes. This CMAS is being isolated at the
            request of CMAS (cmasname).
  

Local fix

• Simply restarting the isolated CMAS may bring it back into the
  CICSplex network

  When multiple CMASs connect to the Maintenance Point (MP) CMAS
  at the same time, and one of its CMASs has had its EYUDREP
  upgraded using the EYU9XDUT utility, then it is possible for
  other CMASs, that have MASs active, to be isolated.
  This problem is due to timing between the multiple CMASs
  connecting, including one where the data repository has been
  updated in the described manner. It could also occur if
  no definitional updates have been made to the CICSPlex SM
  data repository for at least two week prior to the
  CMAS restart.
  
  Method CPLT (EYU0CPLT) reread the CICSplex level,
  CPLXCMAS_SYNCDATA, just before it was used so it knew about the
  latest changes. However it didn't know about MPSYNCCR record
  additions in some cases, leading to delete/define of the remote
  CICSplex definition and possible CMAS isolations as the new data
  was propagated.
  

Problem conclusion

• This APAR rereads the MPSYNCCR records available info,
  CPLXCMAS_FSYNC, just before it uses it so it knows if it can
  do an incremental upgrade of the CICSplex rather than a
  delete/define, which can be more disruptive.
