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.
