Osservazioni

Testo aggiornato:5 dicembre 2005

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

When this property is true, Notification Services creates a row for each notification in the NSDistributionLog table before sending the notification. The distributor then logs pre-delivery information, including the notification ID, notification class, distributor, and delivery request time.

Notification logging has a negative impact on application performance because Notification Services logs information one notification at a time. Unless you use notification log data for all notifications, set this value to false. Notification Services still logs notification text and status for failed notifications.

To view log data, use the Vista NS<NotificationClassName>NotificationDistribution.

Esempio

The following examples show how to set all application execution settings, including logging behavior:

// 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
