When attempting to start the listener in our new db server we get an error like the one below.

Problem:
The hosts file does not contain the correct address or name for the server. This can also occur if the loopback address is not present. Edit /etc/hosts and verify that the host name and address are correct. Also verify that 127.0.0.1 localhost.localdoman localhost are present.
Save the changes and restart the listener.
