Error description

  • In WebSphere Application Server v8.5.5.15, a cluster of 2 JVMs
    is added as a bus member with one messaging engine configured
    and the restrictLongDBLock property is set to true. The
    messaging engine may stop running and reports the condition in
    a CWSID0046E message indicating an Exception containing
    the DSRA9110E message.  The messaging engine then fails over to
    the second node, executes for a while and then stops with same
    CWSID0046E/DSRA9110E message. The following errors are logged
    in the SystemOut.log:
    
    CWSIS1600E: Unable to update Messaging Engine status as the
    messaging engine encountered an  exception while acquiring
    ownership on the message store. Exception: com.ibm.ws.sib.
    msgstore.persistence.DatasourceWrapperStoppedException: New
    connections cannot be  provided because the persistence layer
    has been stopped
    
    CWSID0046E: Messaging engine MECluster.000-XXX.Bus detected
    an error and cannot  continue to run in this server.
