ORB Notification
Service (ORBNS)
Service (ORBNS)
The orbns task performs the following functions:
There are different types of event that can continually occur within
Boxer.
The Application Servers (EMS) may be interested in being notified
of occurrences of these events.
Such Application Servers (EMS) may register with orbs (ORBEM)
subscribing to types of event they are interested in.
As the events occur, the concerned Controller Task would notify
orbs (ORBEM), which in-turn will notify the subscribing
Application Servers (EMS).
