Red Hat 3? Wow, talk about blast from the past! Anyways, how to you expect us to help you without telling us anything about what your doing. All I can tell you is that this error is caused by trying use an xserver you do not have access to (possibly as root?).

You will need to grant access to the xsession for the user(and machine?) running oracle.

You can start here

http://tldp.org/HOWTO/Remote-X-Apps-6.html

then google around for a bit for XAuthority.

Post back if you are still having issues.

**edit**
also, running 'xhost +' is a HUGE security whole, FYI.

Don't use xhost or you will open up your network to any 12 year old with a hacking tutorial. You will need a much more indepth approach, thus Xauthority (also search for Xauth). There are many howtos on this topic. I would start by reading the one I gave you.
