Weblogic t3 url configuration (using property file)

Anybody know which property file or configuration file has the T3 url for weblogic 12c server stored. I have to edit/change the T3 url via config/property file by logging into server. (not via management console). There is some constraint that I do not have to use management console. I want to change it via command prompt. I have googled this but couldn't find this info anywhere.

Thanks for the help.

Solution

You can use WLST in order to change the server's listen address.
WLST is under ${WL_HOME}/common/bin/wlst.sh
Commands :

connect("<USERNAME>","<PASSWORD","<HOST:PORT>")
edit()  
startEdit()  
cd("/Servers/<SERVER NAME>")  
set("ListenAddress","<NEW LISTEN ADDRESS>")  
save()  
activate()  
disconnect()
