How to change the weblogic Admin server port number

Task:

To change the port number of weblogic Admin server. The port number was set to the default value of 7001.

Version:

Weblogic 12.1.2.0.0

Action:

The easiest method is to simply update the port number in the weblogic conole page and save the change. 

Connect to weblogic conole using the current port number

Eg: http:<hostname>:7001/console

Navigate to Servers => Click on the AdminServer(admin)
We would be at the configuration tab of AdminServer now. Just update the value in the Listen Port: column to new value. For eg: 7010 and then click Save button, available at the bottom of that page. That would make the trick.

We can immediately verify the change by accessing the URL through the new port number. But the page would be accessible through both new and old port numbers until we restart the AdminServer. So better to restart the AdminServer so that the console URL is accessible only through the modified port number.

Alternative Approach:

Add the port number in the config.xml file.

Stop the weblogic services. Take a backup of config.xml file. If we are using the default port number of 7001, then its entry would not be there in the file. So we have to add the tags to reflect the new port number.

Add following two lines to the config.xml under <Server> <name>AdminServer</name> tag

<listen-port>7010</listen-port>
<listen-port-enabled>true</listen-port-enabled>

Restart the AdminServer. Now it would be running in new port
