Creating Important Aspects of Notification Services - Creating a Generator
(Page 3 of 7 )
A generator named StockWatchGenerator is created in the CreateGenerator() method of Example 18-1. The code follows:
private static void CreateGenerator()
{
// create a new generator for the application
Generator g = new Generator(a, "StockWatchGenerator");
g.SystemName = nsServer;
a.Generator = g;
Console.WriteLine("Created generator: " + g.Name);
}
TheGeneratorobject represents the generator for a Notification Services application. TheGenerator property of theApplication class returns the generator for the application. You have to specify theGeneratorproperty of theApplicationobject before adding the application to the Notification Services instance. An application has only one generator, which handles rule processing for the application.
TheSystemNameproperty of theGenerator class must be specified, and cannot be any of the following:localhost,., an IP address, or any string containing a backslash (\).
Creating a Distributor
A distributor named StockWatchDistributor is created in the CreateDistributor() method of Example 18-1. The code follows:
private static void CreateDistributor()
{
Distributor d = new Distributor(a, "StockWatchDistributor");
d.SystemName = nsServer;
d.QuantumDuration = new TimeSpan(0, 0, 15);
a.Distributors.Add(d);
Console.WriteLine("Added distributor: " + d.Name);
}
TheDistributor object represents a distributor for a Notification Services application. Each application must have one distributor that controls formatting and distribution of notifications. If an application has multiple distributors, each one must be installed on a different server. TheQuantumDurationproperty specifies the distributor work item polling interval, which is 15 seconds in this example.
The NMO classes for managing distributors are described in Table 18-11.
Table 18-11. NMO classes for managing distributors
| Class | Description |
| Distributor | Represents a distributor for a Notification Services application. |
| DistributorCollection | Represents a collection of distributors asDistributorobjects. TheDistributors property of theApplicationclass returns the distributors used to distribute notifications to delivery channels for the Notification Services application. |
