停用發行和散發
本主題描述如何使用 SQL Server Management Studio、Transact-SQL 或 Replication Management Objects (RMO) ,在 SQL Server 2014 中停用發行和散發。
您可以執行下列工作:
刪除「散發者」上的散發資料庫。
停用所有使用「散發者」的「發行者」,以及刪除這些「發行者」上的所有發行集。
刪除所有的發行集訂閱。 發行集和訂閱資料庫中的資料不會刪除,不過它會遺失與任何發行資料庫的同步處理關聯性。 若要刪除「訂閱者」中的資料,您必須手動刪除。

開始之前
必要條件
- 若要停用發行和散發,所有散發和發行集資料庫都必須在線上。 如果存在散發或發行集資料庫的任何 「資料庫快照集」 ,則必須先卸除這些快照集,然後才能停用發行和散發。 資料庫快照集是資料庫的唯讀離線副本,與複寫快照集無關聯。 如需詳細資訊,請參閱資料庫快照集 (SQL Server)。
使用 SQL Server Management Studio
使用「停用發行與散發精靈」停用發行和散發。
停用發行和散發
連線至您想在 Microsoft SQL Server Management Studio 中停用的發行者和散發者,然後展開伺服器節點。
以滑鼠右鍵按一下 [複寫] 資料夾,然後按一下 [停用發行與散發] 。
完成「停用散發暨發行精靈」中的步驟。
使用 TRANSACT-SQL
您可以使用複寫預存程序來以程式設計的方式停用發行和散發。
停用發行和散發
停止所有複寫相關的作業。 如需作業名稱清單,請參閱< 複寫代理程式安全性模型>一節中的「SQL Server Agent 下的代理程式安全性」。
在訂閱資料庫的每一個訂閱者上,執行 sp_removedbreplication 從資料庫中移除複寫物件。 這個預存程序將不會移除散發者上的複寫作業。
在發行集資料庫的發行者上,執行 sp_removedbreplication 從資料庫中移除複寫物件。
如果發行者使用遠端散發者,請執行 sp_dropdistributor。
在散發者上執行 sp_dropdistpublisher。 應該針對散發者上註冊的每一個發行者執行此預存程序一次。
在散發者上,執行 sp_dropdistributiondb 來刪除散發資料庫。 應該針對散發者上的每一個散發資料庫執行此預存程序一次。 這樣也會移除與散發資料庫有關的任何佇列讀取器代理程式作業。
在散發者上,執行 sp_dropdistributor 從伺服器移除散發者的指定。
注意
如果在您執行 sp_dropdistpublisher 和 sp_dropdistributor之前,尚未卸除所有複寫發行和散發物件,這些程序將會傳回錯誤。 若要在卸除了發行者或散發者時,一併卸除所有複寫相關的物件, @no_checks 參數必須設定為 1。 如果發行者或散發者已離線或是無法連上, @ignore_distributor 參數可以設定為 1 ,好讓它們可以卸除;但是,必須手動移除任何留下來的發行和散發物件。
範例 (Transact-SQL)
這個範例指令碼會從訂閱資料庫中移除複寫物件。
-- Remove replication objects from the subscription database on MYSUB.
DECLARE @subscriptionDB AS sysname
SET @subscriptionDB = N'AdventureWorks2012Replica'
-- Remove replication objects from a subscription database (if necessary).
USE master
EXEC sp_removedbreplication @subscriptionDB
GO
此範例指令碼會停用當做發行者和散發者之伺服器上的發行和散發,並卸除散發資料庫。
-- This script uses sqlcmd scripting variables. They are in the form
-- $(MyVariable). For information about how to use scripting variables
-- on the command line and in SQL Server Management Studio, see the
-- "Executing Replication Scripts" section in the topic
-- "Programming Replication Using System Stored Procedures".
-- Disable publishing and distribution.
DECLARE @distributionDB AS sysname;
DECLARE @publisher AS sysname;
DECLARE @publicationDB as sysname;
SET @distributionDB = N'distribution';
SET @publisher = $(DistPubServer);
SET @publicationDB = N'AdventureWorks2012';
-- Disable the publication database.
USE [AdventureWorks2012]
EXEC sp_removedbreplication @publicationDB;
-- Remove the registration of the local Publisher at the Distributor.
USE master
EXEC sp_dropdistpublisher @publisher;
-- Delete the distribution database.
EXEC sp_dropdistributiondb @distributionDB;
-- Remove the local server as a Distributor.
EXEC sp_dropdistributor;
GO
使用 Replication Management Objects (RMO)
停用發行和散發
移除使用散發者之發行集的所有訂閱。 如需相關資訊,請參閱 Delete a Pull Subscription 以及 Delete a Push Subscription。
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 Delete a Publication。
使用 ServerConnection 類別建立與散發者的連接。
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。
(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。呼叫 Remove 方法。
true
如果「發行者」和「散發者」位於不同的伺服器上,以及「發行者」應該在「散發者」端卸載,而不先確認發行集已不存在於「發行者」端,則傳遞 的值。建立 ReplicationServer 類別的執行個體。 傳遞步驟 3 的 ServerConnection 物件。
呼叫 UninstallDistributor 方法。 傳遞的 值
true
,強制移除散發者端的所有複寫物件,而不需要先確認所有本機發行集資料庫都已停用,而且已卸載散發資料庫。
範例 (RMO)
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。
