I've managed to successfully install oracle 9.2.4 on a RHE4.
My only problem is that i get the error message :
Xlib : connection to `0:0` refused by server
( i got this when doing the installation and the same running enterprise manager)

However when i run the following command the problem is fixed
Xhost + local:root then
Xhost +localracle - the user i created

After running the above i can go ahead with the installation.
My problem is that i have to run this each time i log off.

Is there any config file i can edit to solve this.

thanks

look at man xhost, xauth, startx

also you have X initialisation files,
usually .xinitrc or .xsessionrc or something
which are called when you start X.
you can put the xhost call in there (easy)

I think it's
.xinitrc if you manually start X
.xsessionrc if you use a graphical login.

i've been trying to do add this
add export XAUTHORITY=/home/name/.Xauthority to /root/.bashrc
- where exactly is this supposed to go:
the moment i reboot my machine then i cant log in and have to log in failsafe mode to undo.(Xlib : connection to `0:0` refused by server)

is this solution platform specific - i'm using RHE4


thanks

not sure, can't test here,

remove the .Xauthority

I'd say do it in .xsessionrc

anyone with a solution to this ?
so far nothing seems to work

thanks

Hi M_C,

You didn't say what you did when you got the error message. From the fix I guess you ran an X11 client as oracle when the X11 server was controlled by another user, hence oracle wasn't authorized to access the server.

Often it's easiest to ssh into the same box as the other user, e.g., "ssh -X oracle@localhost" and let SSH handle X authority.

Random hints:

• If you don't want to type oracle's password to ssh, put your public id into ~oracle/.ssh/authorized_keys. Then whoever gets into your account can also get into oracle.
• You use "local" above; usually it's "localhost" or "localhost.localdomain".
• I read "xhost +..." is an older and not very secure mechanism. I use "xauth" instead: As the owner of the X server, "xauth l :0" (or whatever is your $DISPLAY). It will print something like "mybox/unix:0 MIT-MAGIC-COOKIE-1 4c07f1c708040929e8fb2332badb39d5". Then as the other user (oracle) "xauth add MIT-MAGIC-COOKIE-1 4c07f1c708040929e8fb2332badb39d5". As before, you'll have to repeat this every time you restart the X server.
