patching supportcentre via console access (linux)

Hi Tech Support

Our company just purchase the license for Support Center Plus (SCP),

our server is using Linux Centos 5, and we hosted the server in one hosting company

the Support Center Plus is running well, but since there is a patch, I try to patch the SCP

right now I only have access via ssh to our server in the hosting company

here is the step that i've been done to patch the SCP

I try to stop the SCP using sh shutdown.sh -S and it is succesfull

then I try to apply the patches using sh UpdateManager.sh but then I hit an error

[root@mercury69 bin]# sh UpdateManager.sh
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I try to read in Google, it is because the program try to pop up a window, since now I dont have the remote desktop connection to my Linux box, is it possible to apply the patches with SSH connection only ?

then I try to start the service again using sh run.sh command, the command is executed succesfully but the problem once I close my SSH windows, it seems the SCP also was shut down, so any idea to start the service remotely using SSH connection ??
