Eigenschaftswert

An Int32 value that specifies the maximum number of scheduled subscriptions that can be processed during a single generator quantum.

Hinweise

Aktualisierter Text:05. Dezember 2005

Use this property to help guard against an unexpectedly large number of subscriptions entered into the application.

Subscription throttles apply to scheduled rules only, not event-driven rules.

During each quantum, the generator gets the current set of scheduled subscriptions for each subscription class and counts the subscriptions. If the subscription throttle value is exceeded, the generator abandons the quantum.

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

If you set the subscription throttle value to 0, there is no limit to the number of scheduled subscriptions processed from a subscription class during a quantum.

Beispiel

The following examples show how to set all application execution settings, including the subscription 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
