Gets or sets a value that indicates how the application processes event batches.

Namespace: Microsoft.SqlServer.Management.Nmo
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

Syntax

'Declaration
Public Property ProcessEventsInOrder As Boolean

public bool ProcessEventsInOrder { get; set; }

public:
property bool ProcessEventsInOrder {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_ProcessEventsInOrder ()

/** @property */
public void set_ProcessEventsInOrder (boolean value)

public function get ProcessEventsInOrder () : boolean

public function set ProcessEventsInOrder (value : boolean)

Property Value

true if Notification Services processes event batches in the order in which they arrived (sub-quantum sequencing); false if Notification Services processes all event batches that arrived during a quantum at the same time (quantum sequencing).

Remarks

Updated text:5 December 2005

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

This property provides a choice between strict data correctness and generator performance. If the value is false, Notification Services uses quantum sequencing. For more information, see Specifying the Event Processing Order.

Example

The following examples show how to set all application execution settings, including event processing 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
