如何：建立提取訂閱 (RMO 程式設計)

  • 發行項

您可以使用「複寫管理物件 (RMO)」以程式設計的方式建立提取訂閱。用於建立提取訂閱的 RMO 類別依該訂閱所屬的發行集類型而定。

若要建立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」和「發行者」的連接。

  2. 使用步驟 1 中的「發行者」連接建立 TransPublication 類別的執行個體。指定 Name、DatabaseName 和 ConnectionContext。

  3. 呼叫 LoadProperties 方法。如果此方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上不存在該發行集。

  4. 在 Attributes 屬性和 AllowPull 之間執行位元運算邏輯 AND (Visual C# 中的 & 和 Visual Basic 中的 And)。如果結果為 None，則將 Attributes 設為 Attributes 和 AllowPull 之間位元運算邏輯 OR (Visual C# 中的 | 和 Visual Basic 中的 Or) 的結果。然後呼叫 CommitPropertyChanges 以啟用提取訂閱。

  5. 如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱＜Creating, Altering, and Removing Databases＞。

  6. 建立 TransPullSubscription 類別的執行個體。

  7. 設定下列訂閱屬性：

    • 將 ConnectionContext 設為到步驟 1 中建立之「訂閱者」的 ServerConnection。
    • 將 DatabaseName 設為訂閱資料庫的名稱。
    • 將 PublisherName 設為「發行者」的名稱。
    • 將 PublicationDBName 設為發行集資料庫的名稱。
    • 將 PublicationName 設為發行集的名稱。
    • SynchronizationAgentProcessSecurity 的 Login 和 Password (或 SecurePassword) 欄位，為「散發代理程式」在「訂閱者」上執行時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「訂閱者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
      ms147314.note(zh-tw,SQL.90).gif附註：
      當訂閱是由 sysadmin 固定伺服器角色的成員建立時，不需要設定 SynchronizationAgentProcessSecurity，但還是建議您對其進行設定。在這種情況下，代理程式會模擬「SQL Server 代理程式」帳戶。如需詳細資訊，請參閱＜複寫代理程式安全性模型＞。
    • (選擇性) CreateSyncAgentByDefault 的 true 值，以建立用於同步處理訂閱的代理程式作業。如果指定 false (預設值)，則只能以程式設計的方式同步處理訂閱，而且您在從 SynchronizationAgent 屬性存取此物件時必須指定其他屬性 TransSynchronizationAgent。如需詳細資訊，請參閱＜如何：同步處理提取訂閱 (RMO 程式設計)＞。
      ms147314.note(zh-tw,SQL.90).gif附註：
      Microsoft SQL Server Express Edition 不支援「SQL Server 代理程式」。當您為「Express Edition 訂閱者」指定值 true 時，不會建立代理程式作業。不過，在「訂閱者」上會儲存重要的訂閱相關中繼資料。
    • (選擇性) 在使用「SQL Server 驗證」連接到「散發者」時，設定 DistributorSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。

  8. 呼叫 Create 方法。

  9. 使用步驟 2 中 TransPublication 類別的執行個體，呼叫 MakePullSubscriptionWellKnown 方法，以使用「發行者」註冊提取訂閱。如果此註冊已存在，則會發生例外狀況。

若要建立合併式發行集的提取訂閱

  1. 使用 ServerConnection 類別建立到「訂閱者」和「發行者」的連接。

  2. 使用步驟 1 中的「發行者」連接建立 MergePublication 類別的執行個體。指定 Name、DatabaseName 和 ConnectionContext。

  3. 呼叫 LoadProperties 方法。如果此方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上不存在該發行集。

  4. 在 Attributes 屬性和 AllowPull 之間執行位元運算邏輯 AND (Visual C# 中的 & 和 Visual Basic 中的 And)。如果結果為 None，則將 Attributes 設為 Attributes 和 AllowPull 之間位元運算邏輯 OR (Visual C# 中的 | 和 Visual Basic 中的 Or) 的結果。然後呼叫 CommitPropertyChanges 以啟用提取訂閱。

  5. 如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱＜Creating, Altering, and Removing Databases＞。

  6. 建立 MergePullSubscription 類別的執行個體。

  7. 設定下列訂閱屬性：

    • 將 ConnectionContext 設為到步驟 1 中建立之「訂閱者」的 ServerConnection。
    • 將 DatabaseName 設為訂閱資料庫的名稱。
    • 將 PublisherName 設為「發行者」的名稱。
    • 將 PublicationDBName 設為發行集資料庫的名稱。
    • 將 PublicationName 設為發行集的名稱。
    • SynchronizationAgentProcessSecurity 的 Login 和 Password (或 SecurePassword) 欄位，為「合併代理程式」在「訂閱者」上執行時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「訂閱者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
