Follow these steps to change the port number Serena Dashboard runs on, under its Tomcat installation, from the default of 8080.
To change the port number:
Open server.xml in a text or XML editor. By default, this file resides under C:\Program Files\Serena\Common\tomcat\6.0\conf. If you have installed the Serena Tomcat server elsewhere, locate the file in that directory.
Locate all instances of the following parameter:
port="8080"
And update it to the correct port number.
Save the server.xml file.
Restart the Serena Tomcat service.
Enter the Dashboard login URL with the new port number in a browser window and verify that the login screen appears correctly:
http://<servername>:<port>/dashboard/login
For example, if the server name is dashboard and the port number is 9090, enter:
http://dashboard:9090/dashboard/login
