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
ADMU0128I: Starting tool with the DecisionServerNode01 profile
ADMU3100I: Reading configuration for server: DecisionServerNode01-DSServer
ADMU3201I: Server stop request issued. Waiting for stop status.
ADMU4000I: Server DecisionServerNode01-DSServer stop completed.


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

ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/DecisionServerNode01/logs/DecisionServerNode01-DSServer/startServer.log
ADMU0128I: Starting tool with the DecisionServerNode01 profile

ADMU3200I: Server launched. Waiting for initialization status.
ADMU3000I: Server DecisionServerNode01-DSServer open for e-business; process id
           is 61952

and all is well.

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

Visual Studio Code - Wow 🙀

Why did I not know that I can merely hit [cmd] [p]  to bring up a search box allowing me to search my project e.g. a repo cloned from GitHub...
