Answer 1

Hi;
Installation on sever.
Am accessing server using putty.Its mean you use puty for access your server. I suggest follow those steps:
1. login as root and run
service vncserver status << if is stop run it, if its already running use below command
ps -ef|grep vnc << it will show you which is already using like below
root 5900 1 0 Oct18 ? 00:00:06 Xvnc :2 -desktop abcmachine.xx.com:2 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5902 -pn
Its mean you use 2.0 which you will use for make installation
as root user use below:
export DISPLAY=serverIp:2.0
xhost +
Download vncviwer and install it on your machine (http://www.realvnc.com/products/download.html), dont forget you will use client not server option
su - oracle
export DISPLAY=serverIp:2.0
xhost +
run /runInstaller
open vncviwer and run it
type to screen serverIP:2.0 than enter pass
You should see inst. screen
