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
Cannot launch application oracle.sysman.vtcConsole.VTCConsole
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.
I don't know much about OEM, but this err is a unix issue. It seems that you're not at the console when you exec this command. Here's what you need to do, "xhost +" you probably need to be root for this. export your display like so, export DISPLAY=xxx.xxx.xxx.xxx:0.0 where xxx is your ip address. The export display command may vary according to the type of shell you are using. Hope this helps.
