解説
MergeSynchronizationAgent クラスでは、次のレプリケーション タスクを実行するための機能がサポートされています。
サブスクリプションの同期をとります。
同期中にアップロード フェーズのみを実行するか、ダウンロード フェーズのみを実行するか、それとも両方のフェーズを実行するかを指定します。
必要なデータがサブスクリプションにあることを検証します。
サブスクリプションの初期スナップショットを適用するときに使用できる別のスナップショット フォルダを指定します。
MergeSynchronizationAgent クラスは、SQL Server 2000 および SQL Server 2005 の両方で実行中のパブリッシャとサブスクライバで使用できます。
MergeSynchronizationAgent クラスは、SQL Server 2000 で実行中のディストリビュータでは使用できません。

使用例
次の例では、プッシュ サブスクリプションの同期をとるために、SynchronizationAgent プロパティからアクセスされる MergeSynchronizationAgent クラスのインスタンスで Synchronize メソッドを呼び出しています。
// Define the server, publication, and database names.
string subscriberName = subscriberInstance;
string publisherName = publisherInstance;
string publicationName = "AdvWorksSalesOrdersMerge";
string subscriptionDbName = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";
// Create a connection to the Publisher.
ServerConnection conn = new ServerConnection(publisherName);
MergeSubscription subscription;
try
{
// Connect to the Publisher
conn.Connect();
// Define the subscription.
subscription = new MergeSubscription();
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 Merge 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();
}
' Define the server, publication, and database names.
Dim subscriberName As String = subscriberInstance
Dim publisherName As String = publisherInstance
Dim publicationName As String = "AdvWorksSalesOrdersMerge"

' If the push subscription exists, start the synchronization.

' Synchronously start the Merge Agent for the subscription.
' Log agent messages to an output file.

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.")
End If

Finally

End Try
次の例では、マージ サブスクリプションの同期をとるために MergeSynchronizationAgent クラスのインスタンスを使用しています。CreateSyncAgentByDefault の値を false にしてプル サブスクリプションが作成されているため、追加のプロパティを指定する必要があります。
