IBM Operational Decision Manager 8.5 - Exception seen on first startup of Decision Server cluster

I've now seen this twice ( and, therefore, it is repeatable ) when I first start my Decision Server cluster - to be more specific, the cluster is automatically started by the build process, via this script: -

$ export ODM_HOME=/opt/IBM/ODM85/
$ /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/configureDSCluster.sh -dmgrAdminUsername wasadmin -dmgrAdminPassword passw0rd -clusterPropertiesFile ./configureDSCluster.properties -createNode -targetNodeName DecisionServerNode01 -dmgrHostName rhel6.uk.ibm.com -dmgrPort 8879

This is what I see in the SystemOut.log file: -

$ view /opt/IBM/WebSphere/AppServer/profiles/DecisionServerNode01/logs/DecisionServerNode01-DSServer/SystemOut.log

I don't know precisely why it does this BUT the solution is simple :-)

Restart the cluster: -

$ /opt/IBM/WebSphere/AppServer/profiles/DecisionServerNode01/bin/stopServer.sh DecisionServerNode01-DSServer -user wasadmin -password password

ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/DecisionServerNode01/logs/DecisionServerNode01-DSServer/stopServer.log

$ /opt/IBM/WebSphere/AppServer/profiles/DecisionServerNode01/bin/startServer.sh DecisionServerNode01-DSServer

and all is well.

PS Love the scripting to cluster Decision Center and Decision Server, makes ODM builds far more fun :-)
