AddNode script fails with an ADMU0042E error
 Technote (troubleshooting)
 
Problem(Abstract)
When executing an addnode.sh/bat, the script fails to federate the Base Node to the Network Deployment Manager cell, and issues the following error:

AdminTool A ADMU0042E: The addNode/removeNode operation lock could not be released at the Deployment Manager. You may need to invoke AdminOperations.forceNodeFederationOrRemovalTokenReset operation to manually complete this final step of addNode or removeNode.
 
Cause
This error can be caused by one of the two following scenarios.
 
Resolving the problem


Scenario one

The Network Deployment Manager token is used or locked.

To release the token, wait 30 minutes for the token to expire, or run the following commands in wsadmin:

wsadmin>set a [$AdminControl completeObjectName type=AdminOperations,process=dmgr,*]

Returns the following before the wsadmin prompt if successful:
WebSphere:platform=common,cell=chewiNetwork1,version=5.0,name=AdminOperations,mbeanIdentifier=AdminOperations,type=AdminOperations,node=chewiManager1,process=dmgr

wsadmin>$AdminControl invoke $a forceNodeFederationOrRemovalTokenReset

Returns back to the wsadmin prompt.

Scenario two

The dmgr process is stopped during the federation process.

Review the dmgr logs to determine if the process stopped, if the process crashed, or if something else occurred during the federation process. You must determine why it stopped and if it will stop again the next time you try to federate the Base node.

One interesting case where the addNode script causes itself to fail during the federation process is when the addNode script pings all Application Servers on that installation through the SOAP_CONNECTOR_ADDRESS. If a WebSphere process is listening, the addNode script issues a stop command to stop the WebSphere process.

If the Base and ND nodes are on the same machine and the SOAP_CONNECTOR_ADDRESS of one Application Server matches the SOAP_CONNECTOR_ADDRESS port of the dmgr, the addnode script stops the dmgr, causing the script to fail.
