The NMS retrieves all active alarms on the EMS and on managed element objects. The NMS
filters alarms based on probable cause, perceived severity, and managed element name.
1.3 Overview of CORBA Services
GateWay/CORBA uses two CORBA services—naming service and notification service. The
naming service is required for GateWay/CORBA to function. If the notification service is not
available, alarm and event notifications are not forwarded to the OSS. By default, the naming
and notification services are installed on the Prime Optical server during the GateWay/CORBA
installation. However, the CORBA services can be located anywhere as long as they are
accessible from the Prime Optical server on which GateWay/CORBA is installed. The OSS
application(s) must also use the same instances of the naming service and the notification
service.
1.3.1 Naming Service
GateWay/CORBA and the other Prime Optical server processes must use a naming service in
order to operate. GateWay/CORBA includes the OpenFusion naming service product. By
default, GateWay/CORBA is configured to use OpenFusion. However, you can configure
GateWay/CORBA and the Prime Optical server to use a different centralized naming service. For
1.3.2 Notification Service
GateWay/CORBA must use a CORBA notification service to report faults and events.
GateWay/CORBA includes the PrismTech OpenFusion notification service product, and is
configured by default to use it. As with the naming service, you can configure GateWay/CORBA
The following scenarios describe possible configurations of the naming and notification
services.
