when you run installer and get "DISPLAY not set. please set the DISPLAY and try again"
simply follow these steps it works. my target was to login to oracle in order to install oracle database 12c
1) Log on to oracle linux as root
2) Open a terminal
3) echo $DISPLAY (get this value you have to use it after login to oracle my case it was :0)
4) enter 'xhost +'
5) enter 'su - oracle'
6) enter 'export DISPLAY=:0'
7) runInstaller (or use whatever installer is required)
if you are have an option to use any other terminal then putty i will use mobaxterm, you dont need to do all these settings in order to run GUI interface.
