This is a point of confusion of X clients vs. an X server. An X
server can be anywhere on a TCP/IP (or DECnet) connected network,
separate from the clients. The server is what talks to the video
system, keyboard, and pointing devices.
The correct approach is to have the beefy Oracle server chugging away
in the computer room with no framebuffer installed (Why does a server
need a graphical display? It doesn't!) and a graphical workstation
(running an X server) on the admin's desk. The admin runs the app on
the database server, the X client part of which connects to the admin's
workstation and opens a window.
This is the Right Way To Do Things(tm).
FWIW, I agree. For obscure political or technical reasons (before my time
there) it wasn't setup that way.
