public void Enable ()
public function Enable ()

Notes

When you create a Notification Services instance, it is disabled. Enabling the instance enables all instance and application components, which allows event collection, notification generation, notification distribution, and subscription management.

The Notification Services engine queries the database for the status of its components every 30 seconds. Until the engine picks up the status change, engine components show a status of Enable Pending.

Exemple

The following examples show how to create, register, and enable an instance of Notification Services:

// Set Database Engine instance and 
// Notification Services object
server = new smo.Server(sqlServer);
notificationServices = server.NotificationServices;

// Determine if the instance already exists. If so, exit.
if (server.NotificationServices.Instances.Contains(
    instanceName))
{
    Console.WriteLine("Instance exists and will be deleted.");
    myInstance = notificationServices.Instances[instanceName];
    DeleteInstance(myInstance);
}

// Call ConfigureInstance method to configure the instance
// and define the application(s).
myInstance = ConfigureInstance(notificationServices);

// Create the instance
Console.WriteLine("Creating instance...");
myInstance.Create();

//Optional: Export an Instance Configuration File (ICF)
Console.WriteLine("Exporting ICF...");
myInstance.Export(@"C:\NS\Full", true);

// Register and enable the instance
Console.WriteLine("Registering instance...");
myInstance.RegisterLocal(serviceUserName, servicePassword);
Console.WriteLine("Enabling instance...");
myInstance.Enable();
Console.WriteLine("Done.");
' Set Database Engine server and 
' Notification Services object
server = New smo.Server(sqlServer)
notificationServices = server.NotificationServices

' Determine if the instance already exists. If so, exit.
If server.NotificationServices.Instances.Contains( _
  instanceName) Then
    Console.WriteLine( _
        "Instance exists and will be deleted.")
    myInstance = notificationServices.Instances( _
        instanceName)
    DeleteInstance(myInstance)
End If

' Call ConfigureInstance method to configure the instance
' and define the application(s).
myInstance = ConfigureInstance(notificationServices)

' Create the instance
Console.WriteLine("Creating instance...")
myInstance.Create()

'Optional: Export an Instance Configuration File (ICF)
Console.WriteLine("Exporting ICF...")
myInstance.Export("C:\NS\Full", True)

' Register and enable the instance
Console.WriteLine("Registering instance...")
myInstance.RegisterLocal(serviceUserName, servicePassword)
Console.WriteLine("Enabling instance...")
myInstance.Enable()
Console.WriteLine("Done.")
