Oracle Database Discussions

hello everyone!

please, I wonder if you can help me.
I'm trying to install Oracle 9i 9.2.0.4 on RH4 machine, connect to server through Putty and opening Cygwin for the X session. When I'm doing it from the beginning (i mean after reboot) I'm getting this error:

[oracle@ebisdb2 Disk1]$ sh runInstaller
DISPLAY not set!
Please set DISPLAY and try again.

(the X session is open)

when i'm doing:

[oracle@ebisdb2 Disk1]$ export DISPLAY=127.0.0.1:0.0
[oracle@ebisdb2 Disk1]$ sh runInstaller
[oracle@ebisdb2 Disk1]$ Initializing Java Virtual Machine from /tmp/OraInstall2007-08-20_01-49-04PM/jre/bin/java. Please wait...
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using '127.0.0.1:0.0' as the value of the DISPLAY variable.

i've tried all kind of variations:
export DISPLAY=localhost:0.0
export DISPLAY=:0.0
export DISPLAY=localhost:0
export DISPLAY=:0

I've even put my machine's IP - nothin works..
if i make
[oracle@ebisdb2 Disk1]$ xhost +
xhost: unable to open display "127.0.0.1:0.0"

and further with all kind of IPs that were in DISPLAY variable.

Please, help me or navigate to the right source.
