I have installed the OEL 6.4 in server mode, and now sucessfully using it. And have installed the Oracle databases on it for testing purpose.

Can you please guide me, if i can configure it in Desktop mode. I do not want to re-install it.

As per my understanding, i need to install some GUI packages for this, but not sure..what is the exact method.

Can you please guide me to configure it from Server mode to Desktop mode(GUI).
