如何:刪除發行集 (RMO 程式設計)
您可以使用「複寫管理物件」(RMO) 以程式設計的方式刪除發行集。用來移除發行集的 RMO 類別,將取決於所移除的發行集類型而定。
移除快照式或交易式發行集
使用 ServerConnection 類別建立與發行者的連接。
建立 TransPublication 類別的執行個體。
設定發行集的 Name 和 DatabaseName 屬性,並將 ConnectionContext 屬性設定為在步驟 1 中建立的連接。
檢查 IsExistingObject 屬性,確認該發行集存在。如果這個屬性的值為 false,則表示步驟 3 中的發行集屬性定義錯誤或是此發行集不存在。
呼叫 Remove 方法。
(選擇性) 如果此資料庫沒有任何其他的交易式發行集存在,則可以針對交易式發行停用此資料庫,如下所示:
建立 ReplicationDatabase 類別的執行個體。將 ConnectionContext 屬性設定為步驟 1 中 ServerConnection 的執行個體。
呼叫 LoadProperties 方法。如果此方法傳回 false,請確認此資料庫存在。
將 EnabledTransPublishing 屬性設為 false。
呼叫 CommitPropertyChanges 方法。
關閉連接。
移除合併式發行集
使用 ServerConnection 類別建立與發行者的連接。
建立 MergePublication 類別的執行個體。
設定發行集的 Name 和 DatabaseName 屬性,並將 ConnectionContext 屬性設定為在步驟 1 中建立的連接。
檢查 IsExistingObject 屬性,確認該發行集存在。如果這個屬性的值為 false,則表示步驟 3 中的發行集屬性定義錯誤或是此發行集不存在。
呼叫 Remove 方法。
(選擇性) 如果此資料庫沒有任何其他的合併式發行集存在,則可以針對合併式發行停用此資料庫,如下所示:
建立 ReplicationDatabase 類別的執行個體。將 ConnectionContext 屬性設定為步驟 1 中 ServerConnection 的執行個體。
呼叫 LoadProperties 方法。如果此方法傳回 false,請確認此資料庫存在。
將 EnabledMergePublishing 屬性設為 false。
呼叫 CommitPropertyChanges 方法。
關閉連接。
範例
下列範例會刪除交易式發行集。如果此資料庫沒有任何其他的交易式發行集存在,則也會停用交易式發行。
