Are you logged into server itself or using putty or vnc viewer ? You should be logged in as oracle and not root
export DISPLAY=<ipaddress or hostname>:0.0 echo $DISPLAY $>xclock $> ./runInstaller
I logged in as oracle
I logged in server itself with vmware.
I tried that, but didnt work
Error: Can't open display: ....
I generally use cygwinX and uses xserver and I think in your case xserver is not running. So look into vmware guide , how to setup and configure display.
I tried that, but didnt workTry
su root then type export DISPLAY=:0, to check if it works, type xdpyinfo.

I am struggling with installing 11g on oracle enterprise linux
ssh -x oracle@DBServer
you simply need to log onto the DBServer as OS user oracle with X11 packet forwarding enabled!
