Re: Listener.ora DNS or IP?

If the server IP changes, any client connection using the old IP will fail. So the client should change to using DNS name or the new IP.

Caveat: If the server has more than one network card, thus potentially more than one IP associated with it's DNS entry, the listener binds only to the first IP returned by DNS. The client connection fails whenever DNS returned the IP which the listener isn't bound to.

If the server has one network card, and one IP associated with it's DNS entry, there shouldn't be any problems using DNS name on both the client and server.
