When you configure WebSphere Application Server resources or assign port numbers to other applications, you must avoid conflicts with other assigned ports. In addition, you must explicitly enable access to particular port numbers when you configure a firewall.
Steps for this task
See wasprofile command.
You can change port settings after installation. Edit the profile_root/config/cells/cell_name/nodes/node_name/serverindex.xml file to change the port settings, or use scripting to change the values.
