BobMc gave the right answer. Just an addition to him to give an easy way.

1. You have to change your Listener.ora file if it uses comp name istead of IP.

2. If your clients uses IP in TNSNAMES.ora and you are not changing servers IP as well, then no need any change in clients. If they are using servername go your DNS server and add old name with IP (new if you are changing) (If you are not going to use old computername for another computer). (Your system admin helps you.)
Now when they start searching your old computer name they are going to ask its IP to DNS and DNS going to give its IP. They start communicating with IP.

By this way you dont need to change all clients TNSNAMES.ora file if you dont use old name anymore.
