Chapter 1 Overview of CTM GateWay/CORBA
1.3 Overview of CORBA Services
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
CTM GateWay/CORBA uses two CORBA services—naming service and notification service. The
naming service is required for CTM 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 CTM server during the GateWay/CORBA installation. However,
the CORBA services can be located anywhere as long as they are accessible from the CTM server on
which CTM 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
CTM GateWay/CORBA and the other CTM server processes must use a naming service in order to
operate. CTM GateWay/CORBA includes the OpenFusion naming service product. By default,
CTM GateWay/CORBA is configured to use OpenFusion. However, you can configure
CTM GateWay/CORBA and the CTM server to use a different centralized naming service. For more
information, see B.6 Using Multiple Naming Servers, page B-4.
1.3.2 Notification Service
CTM GateWay/CORBA must use a CORBA notification service to report faults and events.
CTM 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 CTM GateWay/CORBA
to use a different notification service. For more information, see A.1 Overview of Notifications,
page A-1.
