Stop the process that is using the port:

a. Use the kill command to stop the process: kill -9 <PID> where <PID> is the Process ID of the process that is using the port.

b. Change port in serverindex.xml file if required 

c.Stop node and sync with dmgr then start node

Restart the WebSphere Application Server:

a. Go to the WebSphere installation directory: cd /opt/IBM/WebSphere/AppServer/bin

b. Run the command: ./stopServer.sh <server_name> where <server_name> is the name of the server that you modified the port number for.

c. Run the command: ./startServer.sh <server_name> where <server_name> is the name of the server that you modified the port number for.
