Can't connect to X11 window server using 'localhost:0.0'

Question

Hello again,
I tried as you suggested under the GUI environment of Red Hat Linux Enterprise 3 (WS).
=====
[root@Linux2005 /]# su - oracle
[oracle@Linux2005 oracle]$ /OraHome1/Disk1/runInstaller
[oracle@Linux2005 oracle]$ Initializing Java Virtual Machine from /tmp/OraInstall2004-08-18_09-03-45AM/jre/bin/java. Please wait...
Xlib: connection to "localhost:0.0" refused by server
Xlib: No protocol specified
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using 'localhost:0.0' as the value of the DISPLAY variable.

The server does not take it.
What else can I do ? Any ideas ?

I had the same problem (Oracle unbreakable Linux) and tried everything you suggest.
Finally when I implement this in bash_profile of oracle user and relogin:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=TSH1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
runInstaller run as hell!
