If you use the Application(Instance,String) constructor, the default value is 60 seconds. If you use the default constructor, you must set this property.

Ejemplo

The following examples show how to set all application execution settings, including the performance query interval:

// 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
