Node Agent Startup Failure

The default admin port in Application Server 9.1 is 4848 and in Application Server 8.x EE, the default admin port is 4849. When you upgrade from Application Server 8.x EE, you could run into problem while trying to start the default node agent that exists in the target, due to the port clash.

To resolve this problem, edit the das.properties file before starting the target domain or node agent. Change the agent.das.port property to the admin port value in the upgraded domain.xml, which is 4849.

Upgrade tool leaves the node agent in a rendezvous false state. If the agent.bind.status property in nodeagent.properties file is BOUND, change it to UNBOUND. The node agent starts up successfully after making these changes.
