Run X11 programs after SSH and switch to another user

This issue arises when you are logging in as root and trying to launch some X11 programs after doing a switch to user oracle.
One solution is to login directly as the user as which you want to run thos X11 programs.
One more workaround is there.Here you can login as a different user. Thereafter run the below command
xauth list | grep "`hostname`/"| grep `echo $DISPLAY | cut -f2 -d: | cut -f1 -d.`

Copy the output. Then switch to second user and run xauth add as this output as an argument as below
xauth add training/unix:13 MIT-MAGIC-COOKIE-1 57f03bee06be924299b0bedde6499bd1

Now run any X11 programs.
