TransSynchronizationAgent.Synchronize Method

Topic Status: Some information in this topic is pre-release and subject to change in future releases. Pre-release information describes new features or changes to existing features in Microsoft SQL Server 2014.

Starts the Distribution Agent to synchronize the subscription.

Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Replication (in Microsoft.SqlServer.Replication.dll)

public virtual void Synchronize()

Implements

ITransSynchronizationAgent.Synchronize()

This method synchronously starts the Distribution Agent. To start the Distribution Agent asynchronously, call SynchronizeWithJob for a pull subscription or SynchronizeWithJob for a push subscription.

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 = "AdventureWorks2012Replica";
			string publicationDbName = "AdventureWorks2012";

			// 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();
					}
					else
					{
						throw new ApplicationException("There is insufficent metadata to " +
							"synchronize the subscription. Recreate the subscription with " +
							"the agent job or supply the required agent properties at run time.");
					}
				}
				else
				{
					// Do something here if the push subscription does not exist.
					throw new ApplicationException(String.Format(
						"The subscription to '{0}' does not exist on {1}",
						publicationName, subscriberName));
				}
			}
			catch (Exception ex)
			{
				// Implement appropriate error handling here.
				throw new ApplicationException("The subscription could not be synchronized.", ex);
			}
			finally
			{
				conn.Disconnect();
			}
