APAR status

• Closed as program error.

Error description

• If a cluster and one of its constituent servers are bus members,
  removing the cluster from the bus stops the messaging engine on
  the server.
  

Local fix

• Restart the messaging engine which is stopped.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of the default messaging provider in   *
  *                 IBM WebSphere Application Server V6.1        *

  * PROBLEM DESCRIPTION: If a cluster and one of its constituent *
  *                      servers are bus members, removing the   *
  *                      cluster from the bus stops the          *
  *                      messaging engine on the server.         *

  * RECOMMENDATION:                                              *
  *                                                              *
  ****************************************************************
  An application server which is a member of a cluster can
  host a messaging engine for a service integration as follows.
  - Server bus member:
    The application server is made a member of the bus.
    A messaging engine is owned by that server.
  - Cluster bus member:
    The cluster is made a member of the bus.
    One or more messaging engines is created within the
    cluster, which can run on any of the application
    servers in the cluster.
  
  It is valid for an application server in a cluster
  that is a cluster bus member to also be made a server
  bus member.
  
  This issue occurs when cluster bus membership is removed
  for a cluster where one of the application servers in that
  cluster is also a server bus member, and has a running
  messaging engine.
  This server bus member messaging engine is incorrectly
  stopped when the cluster bus membership is removed.
  

Problem conclusion

• The problem is resolved by this fix.
