System Notifications allow an administrator, from Fusion Middleware Control, to raise various event levels. This will further allow developers to create specific tasks based on the message or notification level received from Fusion Middleware Control. For example, the application may be designed to display a message to the user when Notification level 3 is received. This message may have been predefined to tell users that the system will be shutting down for maintenance and they need to exit the application. Five notification levels are being provided (1-5).
