Disable Publishing and Distribution

Applies to: SQL Server Azure SQL Managed Instance

This topic describes how to disable publishing and distribution in SQL Server by using SQL Server Management Studio, Transact-SQL, or Replication Management Objects (RMO).

You can do the following:

  • Delete all distribution databases on the Distributor.

  • Disable all Publishers that use the Distributor and delete all publications on those Publishers.

  • Delete all subscriptions to the publications. Data in the publication and subscription databases will not be deleted; however, it loses its synchronization relationship to any publication databases. If you want the data at the Subscriber to be deleted, you must delete it manually.

Before You Begin

Prerequisites

  • To disable publishing and distribution, all distribution and publication databases must be online. If any database snapshots exist for distribution or publication databases, they must be dropped before disabling publishing and distribution. A database snapshot is a read-only offline copy of a database and is not related to a replication snapshot. For more information, see Database Snapshots (SQL Server).

Using SQL Server Management Studio

Disable publishing and distribution by using the Disable Publishing and Distribution Wizard.

To disable publishing and distribution

  1. Connect to the Publisher or Distributor you want to disable in Microsoft SQL Server Management Studio, and then expand the server node.

  2. Right-click the Replication folder, and then click Disable Publishing and Distribution.

  3. Complete the steps in the Disable Publishing and Distribution Wizard.

Using Transact-SQL

Publishing and distributing can be disabled programmatically using replication stored procedures.

To disable publishing and distribution

  1. Stop all replication-related jobs. For a list of job names, see the "Agent Security Under SQL Server Agent" section of Replication Agent Security Model.

  2. At each Subscriber on the subscription database, execute sp_removedbreplication to remove replication objects from the database. This stored procedure will not remove replication jobs at the Distributor.

  3. At the Publisher on the publication database, execute sp_removedbreplication to remove replication objects from the database.

  4. If the Publisher uses a remote Distributor, execute sp_dropdistributor.

  5. At the Distributor, execute sp_dropdistpublisher. This stored procedure should be run once for each Publisher registered at the Distributor.

  6. At the Distributor, execute sp_dropdistributiondb to delete the distribution database. This stored procedure should be run once for each distribution database at the Distributor. This also removes any Queue Reader Agent jobs associated with the distribution database.

  7. At the Distributor, execute sp_dropdistributor to remove the Distributor designation from the server.

    Note

    If all replication publishing and distribution objects are not dropped before you execute sp_dropdistpublisher and sp_dropdistributor, these procedures will return an error. To drop all replication-related objects when a Publisher or Distributor is dropped, the @no_checks parameter must be set to 1. If a Publisher or Distributor is offline or unreachable, the @ignore_distributor parameter can be set to 1 so that they can be dropped; however, any publishing and distributing objects left behind must be removed manually.

Examples (Transact-SQL)

This example script removes replication objects from the subscription database.

-- Remove replication objects from the subscription database on MYSUB.
DECLARE @subscriptionDB AS sysname
SET @subscriptionDB = N'AdventureWorks2022Replica'

-- Remove replication objects from a subscription database (if necessary).
USE master
EXEC sp_removedbreplication @subscriptionDB
GO

This example script disables publishing and distribution on a server that is a Publisher and Distributor and drops the distribution database.

-- 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'AdventureWorks2022';

-- Disable the publication database.
USE [AdventureWorks2022]
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

Using Replication Management Objects (RMO)

To disable publishing and distribution

  1. Remove all subscriptions to publications that use the Distributor. For more information, see Delete a Pull Subscription and Delete a Push Subscription.

  2. Remove all publications that use the Distributor, and disable publishing for all databases if the Publisher and Distributor are on the same server. For more information, see Delete a Publication.

  3. Create a connection to the Distributor by using the ServerConnection class.

  4. Create an instance of the DistributionPublisher class. Specify the Name property, and pass the ServerConnection object from step 3.

  5. (Optional) Call the LoadProperties method to get the properties of the object and verify that the Publisher exists. If this method returns false, the Publisher name set in step 4 was incorrect or the Publisher is not used by this Distributor.

  6. Call the Remove method. Pass a value of true for force if the Publisher and Distributor are on different servers, and when the Publisher should be uninstalled at the Distributor without first verifying that publications no longer exist at the Publisher.

  7. Create an instance of the ReplicationServer class. Pass the ServerConnection object from step 3.

  8. Call the UninstallDistributor method. Pass a value of true for force to remove all replication objects at the Distributor without first verifying that all local publication databases have been disabled, and distribution databases have been uninstalled.

Examples (RMO)

This example removes the Publisher registration at the Distributor, drops the distribution database, and uninstalls the Distributor.

// Set the Distributor and publication database names.
// Publisher and Distributor are on the same server instance.
string publisherName = publisherInstance;
string distributorName = publisherInstance;
string distributionDbName = "distribution";
string publicationDbName = "AdventureWorks2022";

// Create connections to the Publisher and Distributor
// using Windows Authentication.
ServerConnection publisherConn = new ServerConnection(publisherName);
ServerConnection distributorConn = new ServerConnection(distributorName);

// Create the objects we need.
ReplicationServer distributor =
    new ReplicationServer(distributorConn);
DistributionPublisher publisher;
DistributionDatabase distributionDb =
    new DistributionDatabase(distributionDbName, distributorConn);
ReplicationDatabase publicationDb;
publicationDb = new ReplicationDatabase(publicationDbName, publisherConn);

try
{
    // Connect to the Publisher and Distributor.
    publisherConn.Connect();
    distributorConn.Connect();

    // Disable all publishing on the AdventureWorks2022 database.
