Unknown host after hostname change

I recently replicated a Red Hat 6.5 vm server to a new vm.  After changing the hostname and restarting I tried to ping it by the new name but receive an error "unknown host oral11g2"  If I ping the old hostname, ora11g1, it resolves to 127.0.0.1.  I am not at all familiar with Linux OS so I was hoping someone could point out what the issue is.  I changed the name by using system-config-network.

After reboot, the server shows the new name change but cannot ping it.

Did you add your new hostname entry to your DNS? If not, how would your system know, how to resolve that hostname?

Is there a local entry in the Red Hat OS that I need to add the new hostname to?  If so, where is at?
