Solution

Weblogic.nodemanager.NMException / java.rmi.NoSuchObjectException While Starting AdminServer (Doc ID 2335354.1)

CAUSE

Under DOMAIN_HOME/servers/AdminServer/nodemanager directory, there is a file called startup-copy.properties file.

This file has ADMIN_URL parameter. Adminserver does not need ADMIN_URL parameter defined in start-up.properties. If it is present, then it results in the error.
 

SOLUTION

1. Make sure nodemanager.properties has StartScriptEnabled=true and StartScriptName=startWebLogic.sh
   
2. Under DOMAIN_HOME/servers/AdminServer/nodemanager directory, make sure none of the files have ADMIN_URL parameter.
