What is the proper way to shutdown the OpManager in Linux that does not have UI installed? Shutting down in terminal throws the following errors.
root@server:/opt/ManageEngine/OpManager/bin# ./ShutDownOpManager.sh
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
