Comentários

The TransSynchronizationAgent class supports the ability to programmatically synchronize subscriptions to transactional or snapshot publications.

Exemplos

In the following example, the Synchronize method is called on the instance of the TransSynchronizationAgent class that is accessed from the SynchronizationAgent property to synchronize the push subscription.

           // Define the server, publication, and database names.
            string subscriberName = subscriberInstance;
            string publisherName = publisherInstance;
            string publicationName = "AdvWorksProductTran";
            string subscriptionDbName = "AdventureWorks2008R2Replica";
            string publicationDbName = "AdventureWorks2008R2";

            // Create a connection to the Publisher.
            ServerConnection conn = new ServerConnection(publisherName);

            TransSubscription subscription;

            try
            {
                // Connect to the Publisher.
                conn.Connect();

                // Define the push subscription.
                subscription = new TransSubscription();
                subscription.ConnectionContext = conn;
                subscription.DatabaseName = publicationDbName;
                subscription.PublicationName = publicationName;
                subscription.SubscriptionDBName = subscriptionDbName;
                subscription.SubscriberName = subscriberName;

                // If the push subscription exists, start the synchronization.
                if (subscription.LoadProperties())
                {
                    // Check that we have enough metadata to start the agent.
                    if (subscription.SubscriberSecurity != null)
                    {
                        // Synchronously start the Distribution Agent for the subscription.
                        subscription.SynchronizationAgent.Synchronize();

Segurança de thread

The TransSynchronizationAgent class does not support multithreaded apartments. You can specify a single-threaded apartment by declaring the [STAThread] attribute on the method that is the main entry point for the application. This is the default for Microsoft Windows-based applications that are created by using Microsoft Visual Studio.
