Voorbeelden

Het volgende codevoorbeeld laat zien hoe u HostLockRenewalPeriod gebruikt in een SqlWorkflowInstanceStore.

static void Main(string[] args)
{
    // Create service host.
    WorkflowServiceHost host = new WorkflowServiceHost(new CountingWorkflow(), new Uri(hostBaseAddress));

    // Add service endpoint.
    host.AddServiceEndpoint("ICountingWorkflow", new BasicHttpBinding(), "");

    // Define SqlWorkflowInstanceStoreBehavior:
    //   Set interval to renew instance lock to 5 seconds.
    //   Set interval to check for runnable instances to 2 seconds.
    //   Instance Store does not keep instances after it is completed.
    //   Select exponential back-off algorithm when retrying to load a locked instance.
    //   Instance state information is compressed using the GZip compressing algorithm.
    SqlWorkflowInstanceStoreBehavior instanceStoreBehavior = new SqlWorkflowInstanceStoreBehavior(connectionString);
    instanceStoreBehavior.HostLockRenewalPeriod = new TimeSpan(0, 0, 5);
    instanceStoreBehavior.RunnableInstancesDetectionPeriod = new TimeSpan(0, 0, 2);
    instanceStoreBehavior.InstanceCompletionAction = InstanceCompletionAction.DeleteAll;
    instanceStoreBehavior.InstanceLockedExceptionAction = InstanceLockedExceptionAction.AggressiveRetry;
    instanceStoreBehavior.InstanceEncodingOption = InstanceEncodingOption.GZip;
    host.Description.Behaviors.Add(instanceStoreBehavior);

    // Open service host.
    host.Open();

    // Create a client that sends a message to create an instance of the workflow.
    ICountingWorkflow client = ChannelFactory<ICountingWorkflow>.CreateChannel(new BasicHttpBinding(), new EndpointAddress(hostBaseAddress));
    client.start();

    Console.WriteLine("(Press [Enter] at any time to terminate host)");
    Console.ReadLine();
    host.Close();
}

Opmerkingen

Als de host de vergrendeling niet verlengt (met andere woorden, de lease verlengen) met deze in deze periode, ontgrendelt de persistentieprovider het exemplaar en kan een andere host het exemplaar vergrendelen. De waarde is een TimeSpan van de notatie "uu:mm:ss". De minimaal toegestane waarde is 00:00:01 (1 sec). De standaardwaarde van deze eigenschap is '00:00:30' (30 seconden).
