Sun Java System Application Server 9.1 Upgrade and Migration Guide

Port Conflict Problems

After upgrading the source server to Application Server 9.1, start the domain and then the node agent, which, by default, starts the server instances. If you have upgraded from Application Server 8.x EE, you might face problems while attempting to start the node agent. The domain, clusters, and instances have admin port set to 4849 and the node agent points to 4848. You need to manually modify the admin port to which the node agent points. To change the node agent port, edit the agent.das.port property in the install_dir/nodeagents/node-agent-name/server_name/config/das.properties file.

Start the Admin Console and verify that these servers are started. If any of the servers are not running, in the install_dir/nodeagents/node-agent-name/server_name/logs/server.log file, check for failures that are caused by port conflicts. If there any failures due to port conflicts, use the Admin Console and modify the port numbers so there are no more conflicts. Stop and restart the node agent and servers.
