Hey Govindan,

There's a couple of things you can do.  First, I'm not sure why you would
need the xhost and the DISPLAY variable set, based on what you've shown. 
What would necessitate the need for those is not establishing an
authenticated X session, such as using telnet or possibly "su".

If you've logged onto the graphic console of "testsacx", your authentication
and DISPLAY should already be set up for you.  If you are telnetting, then
the DISPLAY variable needs to point to your *local* X windows box, and not
testsacx.  As an aside, in X11R6 (I believe), the use of xhost may be
superseded and may not work at all, for security reasons.

Your easiest way to get your display is to login to the graphic console
directly (it should look somewhat similar to a Windohs-type login).  If
that's not an option, then you must be running a local X Windows client in
order to have the Oracle graphical installer display to your machine.  Since
I must run MS Windohs here at work, I use CygWin-X for my X display, then
"ssh -Y oracle@myoraclebox" to login to the oracle box.  The "-Y" (or "-X"
in older versions of ssh) will carry your X authentication across to the new
box and automatically setup your DISPLAY variable, provided your admin setup
the sshd daemon to do so (not on by default).

Sound confusing?  It can be, thanks to security holes inherent in using the
xhost method.

Let us know how you login to "testsacx".  That should help clear this up a bit.
