備註

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.

Calling Synchronize is the same as calling the Initialize, Run, and Terminate methods on the SQLDistribution Object (Replication ActiveX).

範例

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 = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";

// 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();
}

    subscription.SubscriberName = subscriberName

    ' If the push subscription exists, start the synchronization.
    If subscription.LoadProperties() Then
        ' Check that we have enough metadata to start the agent.
        If Not subscription.SubscriberSecurity Is Nothing Then

            ' 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 " + _

End Try
