Oracle Default Port

When you first installed oracle, if you haven't changed the port number, the default listening port is 1521. But for the security issue, if you are serious about it, this should be changed to something else. There would be one more step for client setup, you need to specify what port number to connect to your oracle dba server. Which maybe a bit annoying, so most people would leave it as a default option.
