如何：同步處理提取訂閱 (RMO 程式設計)

您可以使用「複寫管理物件 (RMO)」和對複寫代理程式功能的 Managed 程式碼存取，以程式設計的方式同步處理提取訂閱。用於同步處理提取訂閱的類別依該訂閱所屬的發行集類型而定。

附註：
如果您要啟動自發執行的同步處理而不影響應用程式，請非同步啟動代理程式。不過，如果要監視同步處理的結果並在同步處理期間從代理程式接收回呼 (例如，顯示進度列)，您就應該同步啟動代理程式。對於「Microsoft SQL Server 2005 Express Edition 訂閱者」，您必須同步啟動代理程式。

若要同步處理快照式或交易式發行集的提取訂閱

1. 使用 ServerConnection 類別建立到「訂閱者」的連接。

2. 建立 TransPullSubscription 類別的執行個體，並設定下列屬性：

   • 將 DatabaseName 設為訂閱資料庫名稱。
   • 將 PublicationName 設為訂閱所屬發行集的名稱。
   • 將 PublicationDBName 設為發行集資料庫的名稱。
   • 將 PublisherName 設為「發行者」的名稱。
   • 將 ConnectionContext 設為步驟 1 中建立的連接。

3. 呼叫 LoadProperties 方法以取得剩餘的訂閱屬性。如果此方法傳回 false，請確認該訂閱存在。

4. 以下列其中一種方式啟動「訂閱者」上的「散發代理程式」：

   • 在步驟 2 中 TransPullSubscription 的執行個體上呼叫 SynchronizeWithJob 方法。此方法會非同步啟動「散發代理程式」，且控制項會在代理程式作業執行時立即傳回至應用程式。您不可以針對「SQL Server 2005 Express Edition 訂閱者」呼叫此方法，或者如果訂閱是以 CreateSyncAgentByDefault 的 false 值 (預設值) 建立的，也不可以。
   • 從 SynchronizationAgent 屬性取得 TransSynchronizationAgent 類別的執行個體，並呼叫 Synchronize 方法。此方法會同步啟動代理程式，而控制項仍會停留於正在執行的代理程式作業。在同步執行期間，您可以在代理程式執行時處理 Status 事件。

     附註：
     如果您在建立提取訂閱時為 CreateSyncAgentByDefault 指定 false 值 (預設值)，則還需要指定 Distributor、DistributorSecurityMode，以及 (選擇性) DistributorLogin 和 DistributorPassword，這是因為在 MSsubscription_properties 中無法使用訂閱的代理程式作業相關中繼資料。

若要同步處理合併式發行集的提取訂閱

1. 使用 ServerConnection 類別建立到「訂閱者」的連接。

2. 建立 MergePullSubscription 類別的執行個體，並設定下列屬性：

   • 將 DatabaseName 設為訂閱資料庫名稱。
   • 將 PublicationName 設為訂閱所屬發行集的名稱。
   • 將 PublicationDBName 設為發行之資料庫的名稱。
   • 將 PublisherName 設為「發行者」的名稱。
   • 將 ConnectionContext 設為步驟 1 中建立的連接。

3. 呼叫 LoadProperties 方法以取得剩餘的訂閱屬性。如果此方法傳回 false，請確認該訂閱存在。

4. 以下列其中一種方式啟動「訂閱者」上的「合併代理程式」：

   • 在步驟 2 中 MergePullSubscription 的執行個體上呼叫 SynchronizeWithJob 方法。此方法會非同步啟動「合併代理程式」，且控制項會在代理程式作業執行時立即傳回至應用程式。您不可以針對「SQL Server 2005 Express Edition 訂閱者」呼叫此方法，或者如果訂閱是以 CreateSyncAgentByDefault 的 false 值 (預設值) 建立的，也不可以。
   • 從 SynchronizationAgent 屬性取得 MergeSynchronizationAgent 類別的執行個體，並呼叫 Synchronize 方法。此方法會同步啟動「合併代理程式」，而控制項仍會停留於正在執行的代理程式作業。在同步執行期間，您可以在代理程式執行時處理 Status 事件。

     附註：
     如果您在建立提取訂閱時為 CreateSyncAgentByDefault 指定 false 值 (預設值)，則還需要指定 Distributor、DistributorSecurityMode、PublisherSecurityMode、HostName、SubscriptionType、ExchangeType，以及 (選擇性) DistributorLogin、DistributorPassword、PublisherLogin 和 PublisherPassword，這是因為在 MSsubscription_properties 中無法使用訂閱的代理程式作業相關中繼資料。
