public function set NotificationThrottle (value : int)

Valore proprietà

An Int32 value that specifies the maximum number of notifications that can be processed in a single notification class during a single generator quantum.

Osservazioni

Use this property to guard against large numbers of notifications being generated.

During each quantum, the generator runs rules that generate notifications. If the notification throttle is exceeded, the generator throws an error and stops the rule. Other rules within the quantum are not affected unless they also exceed the throttle value.

Testo aggiornato:5 dicembre 2005

If you use the Application(Instance,String) constructor, the default value is 1000. If you use the default constructor, you must set this property.

To turn off the notification throttle, use the value 0.

Esempio

The following examples show how to set all application execution settings, including the notification throttle:

// Define application execution settings
myApplication.QuantumDuration = new TimeSpan(0, 0, 15);
myApplication.PerformanceQueryInterval = new TimeSpan(0, 0, 5);
myApplication.SubscriptionQuantumLimit = 1;
myApplication.ChronicleQuantumLimit = 1;
myApplication.VacuumRetentionAge = new TimeSpan(0, 0, 1);
myApplication.LogBeforeDeliveryAttempts = false;
myApplication.LogNotificationText = false;
myApplication.LogStatusInfo = false;
myApplication.EventThrottle = 500;
myApplication.NotificationThrottle = 500;
myApplication.SubscriptionThrottle = 500;
myApplication.ProcessEventsInOrder = false;

' Define application execution settings
myApplication.QuantumDuration = New TimeSpan(0, 0, 15)
myApplication.PerformanceQueryInterval = New TimeSpan(0, 0, 5)
myApplication.SubscriptionQuantumLimit = 1
myApplication.ChronicleQuantumLimit = 1
myApplication.VacuumRetentionAge = New TimeSpan(0, 0, 1)
myApplication.LogBeforeDeliveryAttempts = False
myApplication.LogNotificationText = False
myApplication.LogStatusInfo = False
myApplication.EventThrottle = 500
myApplication.NotificationThrottle = 500
myApplication.SubscriptionThrottle = 500
myApplication.ProcessEventsInOrder = False
