Error description

• In an IBM Business Process Manager (BPM) Advanced
  three-cluster topology that has non-default service component
  architecture (SCA) bus names (SCA.SYSTEM.<cellName>.Bus and
  SCA.APPLICATION.<cellName>.Bus), the following error is logged
  by the SCA on application cluster members when no messaging
  cluster member is configured on the same managed node
  (profile):
  
  CWSIT0086E: Bus BPM.<deName>.Bus not found
  
  The SCA cannot connect to the service integration bus (SIB)
  messaging engine (ME).

  ****************************************************************
  SIBs are synchronized only to managed nodes (profiles) when
  there is a server configured that uses SIB services.
  Therefore, when no bus is visible on the application cluster
  node, IBM BPM reverts to the default bus name, which does not
  exist.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.0.0 that ensures the SIB
  configuration is synchronized to managed nodes that have
  application cluster members even if no messaging cluster
  members are configured on those managed nodes.
