I was trying to install Management Server on a test machine that has 2 database but I'm running into a problem. I already have OEM running on my client and I can use some of the OEM features but to use performance manager,etc, I need to install the Management Server. So from th korn shell the first thing that I did was to type "oemapp console" and hit enter and this is the message that I received:

$ oemapp console
Xlib: connection to "0:0.0" refused by server
Xlib: Client is not authorized to connect to Server
java.lang.reflect.InvocationTargetExceptionjava.lang.NullPointerException
Cannot launch application oracle.sysman.vtcConsole.VTCConsole
Usage: oemapp
The installed applications are: worksheet, console, dbastudio


NOTE: The cursor is still blinking indicating that there might be some more installation going on but I'm not sure.

Can any one help or explain whats going on?
