I have an oracle host with below settings.

#if [ -z "$REMOTEHOST" ]
#DISPLAY=`hostname`:0.0; export DISPLAY
#DISPLAY=localhost:1; export DISPLAY
#xhost + localhost

If I don't disable them, I will get trouble to run oracle gridware installer. Could anyone help me what each line means?

I want to know clearly what this if clause does!
