如何:停用發行和散發 (RMO 程式設計)

您可以使用「複寫管理物件」(RMO) 以程式設計的方式停用發行和散發。

停用發行和散發

  1. 移除使用散發者之發行集的所有訂閱。如需詳細資訊,請參閱<如何:刪除提取訂閱 (RMO 程式設計)>和<如何:刪除發送訂閱 (RMO 程式設計)>。

  2. 移除使用散發者的所有訂閱,以及停用所有資料庫的發行 (如果發行者和散發者在相同的伺服器上)。如需詳細資訊,請參閱<如何:刪除發行集 (RMO 程式設計)>。

  3. 使用 Serverconnection 類別建立與散發者的連接。

  4. 建立 DistributionPublisher 類別的執行個體。指定 name()()()() 屬性,並傳遞步驟 3 中的 ServerConnection 物件。

  5. (選擇性) 呼叫 LoadProperties 方法,以取得物件的屬性及確認發行者確實存在。如果此方法傳回 false,則表示步驟 4 中設定的發行者名稱不正確,或是此散發者並未使用此發行者。

  6. 呼叫 Remove(Boolean) 方法。如果發行者和散發者位於不同的伺服器上,以及應該在散發者上解除安裝發行者,而不需要先確認發行集是否已經不在發行者上時,請針對 force 傳遞 true 的值。

  7. 建立 ReplicationServer 類別的執行個體。傳遞步驟 3 的 ServerConnection 物件。

  8. 呼叫 UninstallDistributor 方法。針對 force 傳遞 true 的值,可在散發者上移除所有複寫物件,而不需要先確認是否已經停用所有本機發行集資料庫及解除安裝散發資料庫。

範例

此範例會移除散發者上的發行者註冊、捨棄散發資料庫,以及解除安裝散發者。
