Actually it may not work, depending on how X is setup and the version of SSH/SSL installed. I have that problem right now with an older version of SSH on HPUX. Even the venerable "xhost +" gaping security hole workaround didn't work. You could try doing an "echo $DISPLAY" after the initial "ssh -X" (or "ssh -Y") and seeing if you can export that value after the su to oracle, but I doubt that'll work. One of these days I may have enough time to figure it out...
