For NE-related alarms, Prime Optical inserts the original probable cause in the alarm’s 
nativeProbableCause field. The TMF-mapped probable cause is available in the probableCause 
field. 

GateWay/CORBA can integrate with external notification services. When GateWay/CORBA 
starts, a reference to EventNotifyChannelFactory is resolved. GateWay/CORBA makes the 
following attempts to resolve the object: 

1.  Resolve initial references with the default service name of NotificationService to resolve the object. 

You can change the service name by setting the corbagw.notification.ServiceName property in the 
corbagw.properties file. 

2.  Resolve the object through the naming service. The default naming service entry is 

services.NotifyChannelFactory. You can change the naming service entry by setting the 
corbagw.notification.NamingContext property in the corbagw.properties file. 

3.  Resolve the object directly through the Interoperable Object Reference (IOR). You can change the 

URL of the IOR file by setting the corbagw.notification.FactoryIORFile property in the 
corbagw.properties file. The default location for the IOR file is 
file://localhost/CTM_baseDir/cfg/NotificationService.ior. You can specify a URL that points to a 
remote web server. 

While GateWay/CORBA and the bundled notification server are developed and tuned to provide 
high throughput, you might want to take additional steps to improve throughput and avoid any 
loss of notifications. You should implement the StructuredPushConsumer interface defined by 
the Object Management Group (OMG) and implement the push_structured_event method. The 
notification server invokes this method on the NMS. 
  Because all CORBA calls are blocking, the notification server thread blocks until the 

push_structured_event method completes. If you try to perform a time-consuming task 
before the method completes, you will block the notification server. 

To improve throughput, you should receive the event and forward it to another thread for 
processing. 
For example: 

  As shown in the example, you must catch all exceptions, or you will stop receiving 

notifications. 

The following sections list the attributes of each event.
