> You need to install Oracle
Oracle is _horrible_ as far as that goes. One of our customers runs some Oracle reporting apps that _require_ X Windows to be running (and with xhost+ to the other servers that use the reporting app). Yeah, we can configure Xvfb to do the job, but it's a pain. All this so the Oracle app can do some font rasterizing or something.
Other "management" apps are just as bad, requiring a graphic or browser interface (hello, SANsurfer) to do anything useful. Try that when your server is in a private (10.x.x.x) LAN that requires a couple of intervening ssh servers to get to. Yes, it can be done by setting up the right ssh tunnelling, but it's a pain in the butt compared to command line (and scriptable!) access.
Even amongst the apps in a single distro that DO permit an alternate command line mode, it's inconsistent. up2date-nox vs printconf-tui, anyone?
Okay, rant off.
