Port information

The default port with RTC and CLM deployments is:
HTTPS - 9443
HTTP - 9080
Keep in mind that both ports need to be open for RTC to run OOB.

As Sam mentioned above, this information is in the server.xml. If you want to change the port, it needs to be changed before the public URI is set.

If you are a user, you must get this info from the system administrator
if you are the administrator, you should have received this info from the installation team,

if you did not get that, you will have to look in Websphere or Tomcat configuration files to discover it.

on tomcat that is install_location/server/tomcat/conf/server.xml
and is represented on the Connector element (like this from my test server)
<code>
    <Connector port="9780" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="9743" />
</code>

The another possibility to check that is running the following command:
netstat -a -o | grep <PID>
where <PID> is process id for your CLM server running. This will work even for WAS :)
