如何：建立發行集 (RMO 程式設計)

您可以使用「複寫管理物件」(RMO) 以程式設計的方式建立發行集。用來建立發行集的 RMO 類別，將取決於所建立的發行集類型而定。

安全性注意事項
可能的話，會在執行階段提示使用者輸入安全性認證。如果您必須儲存認證，請使用 Microsoft Windows .NET Framework 提供的＜密碼編譯服務＞(英文)。

建立快照式或交易式發行集

使用 ServerConnection 類別建立與發行者的連接。
為發行集資料庫建立 ReplicationDatabase 類別的執行個體、將 ConnectionContext 屬性設定為步驟 1 中的 ServerConnection 執行個體，並呼叫 LoadProperties 方法。如果 LoadProperties 傳回 false，請確認此資料庫確實存在。
如果 EnabledTransPublishing 屬性為 false，請將它設定為 true。
如果是交易式發行集，請檢查 LogReaderAgentExists 屬性的值。如果這個屬性為 true，則表示記錄讀取器代理程式作業已存在此資料庫中。如果這個屬性為 false，請執行下列動作：
- 設定 LogReaderAgentProcessSecurity 的 Login 和 Password 或 SecurePassword 欄位，以提供執行記錄讀取器代理程式所使用之 Microsoft Windows 帳戶的認證。
  
  [!附註]
  
  當發行集是由 sysadmin 固定伺服器角色的成員所建立時，不需要設定 LogReaderAgentProcessSecurity。在這種情況下，代理程式會模擬「SQL Server 」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) 在使用「SQL Server 驗證」連接到發行者時，請設定 LogReaderAgentPublisherSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。
- 呼叫 CreateLogReaderAgent 方法來為資料庫建立記錄讀取器代理程式作業。
建立 TransPublication 類別的執行個體，並為此物件設定下列屬性：
- 將 ConnectionContext 設定為步驟 1 中的 ServerConnection。
- 將 DatabaseName 設為發行的資料庫名稱。
- 將 Name 設定為發行集名稱。
- Transactional 或 Snapshot 的 PublicationType。
- SnapshotGenerationAgentProcessSecurity 的 Login 和 Password 欄位，可提供執行快照集代理程式所使用之 Windows 帳戶的認證。當快照集代理程式要連接本機散發者及進行任何遠端連接 (使用 Windows 驗證) 時，也會使用此帳戶。

- (選擇性) 在使用「SQL Server 驗證」連接到發行者時，請設定 SnapshotGenerationAgentPublisherSecurity 的 SqlStandardLogin 和 SqlStandardPassword (或 SecureSqlStandardPassword) 欄位。
- (選擇性) 使用包含的邏輯 OR 運算子 (Visual C# 中的 | 和 Visual Basic 中的 Or)，並使用排除的邏輯 OR 運算子 (Visual C# 中的 ^ 和 Visual Basic 中的 Xor)，為 Attributes 屬性設定 PublicationAttributes 值。
- (選擇性) 當散發者為非 SQL Server 散發者時，將 PublisherName 設定為散發者的名稱。

呼叫 Create 方法來建立發行集。

安全性注意事項
當利用遠端散發者來設定發行者時，提供給所有屬性的值 (包括 SnapshotGenerationAgentProcessSecurity) 都會以純文字的方式傳給散發者。您應該先加密發行者及其遠端散發者之間的連接，再呼叫 Create 方法。如需詳細資訊，請參閱＜加密 SQL Server 的連接＞。

呼叫 CreateSnapshotAgent 方法來為發行集建立快照集代理程式作業。

建立合併式發行集

使用 ServerConnection 類別建立與發行者的連接。
為發行集資料庫建立 ReplicationDatabase 類別的執行個體、將 ConnectionContext 屬性設定為步驟 1 中的 ServerConnection 執行個體，並呼叫 LoadProperties 方法。如果 LoadProperties 傳回 false，請確認此資料庫確實存在。
如果 EnabledMergePublishing 屬性為 false，請將它設定為 true 然後呼叫 CommitPropertyChanges。
建立 MergePublication 類別的執行個體，並為此物件設定下列屬性：
- 將 ConnectionContext 設定為步驟 1 中的 ServerConnection。
- 將 DatabaseName 設為發行的資料庫名稱。
- 將 Name 設定為發行集名稱。
- SnapshotGenerationAgentProcessSecurity 的 Login 和 Password 欄位，可提供執行快照集代理程式所使用之 Windows 帳戶的認證。當快照集代理程式要連接本機散發者及進行任何遠端連接 (使用 Windows 驗證) 時，也會使用此帳戶。

呼叫 Create 方法來建立發行集。

呼叫 CreateSnapshotAgent 方法來為發行集建立快照集代理程式作業。

範例

此範例會針對交易式發行啟用 AdventureWorks 資料庫、定義記錄讀取器代理程式作業，並建立 AdvWorksProductTran 發行集。必須為此發行集定義發行項。建立記錄讀取器代理程式作業和快照集代理程式作業所需的 Windows 帳戶認證是在執行階段所傳遞。若要了解如何使用 RMO 來定義快照發行項和交易式發行項，請參閱＜如何：定義發行項 (RMO 程式設計)＞。
