How to: Upgrade Replication Scripts (Replication Transact-SQL Programming)

Transact-SQL script files can be used to programmatically configure a replication topology. For more information, see Replication System Stored Procedures Concepts. If you are a member of the sysadmin fixed server role in SQL Server 2005 and you run replication scripts created from SQL Server 2000, the scripts will execute properly. If you are a member of the db_owner fixed database role or another role, the scripts will fail with errors MSSQL_ENG021797 or MSSQL_ENG021798 and must be upgraded.

Security noteSecurity Note

Although you are not required to upgrade scripts that are executed by members of the sysadmin role, we recommend that you modify existing scripts as described in this topic. Specify an account that has minimum permissions for each replication agent as described in the "Permissions Required By Agents" section of the topic Replication Agent Security Model.

These security improvements, which enable more control over permissions by allowing you to explicitly specify the Microsoft Windows accounts under which replication agent jobs are executed, affect the following stored procedures in existing scripts:

  • sp_addpublication_snapshot:

    You should now supply the Windows credentials as @job_login and @job_password when executing sp_addpublication_snapshot (Transact-SQL) to create the job under which the Snapshot Agent runs at the Distributor.

  • sp_addpushsubscription_agent:

    You should now execute sp_addpushsubscription_agent (Transact-SQL) to explicitly add a job and supply the Windows credentials (@job_login and @job_password) under which the Distribution Agent job runs at the Distributor. In versions of SQL Server before SQL Server 2005, this was done automatically when a push subscription was created.

  • sp_addmergepushsubscription_agent:

    You should now execute sp_addmergepushsubscription_agent (Transact-SQL) to explicitly add a job and supply the Windows credentials (@job_login and @job_password) under which the Merge Agent job runs at the Distributor. In versions of SQL Server before SQL Server 2005, this was done automatically when a push subscription was created.

  • sp_addpullsubscription_agent:

    You should now supply the Windows credentials as @job_login and @job_password when executing sp_addpullsubscription_agent (Transact-SQL) to create the job under which the Distribution Agent runs at the Subscriber.

  • sp_addmergepullsubscription_agent:

    You should now supply the Windows credentials as @job_login and @job_password when executing sp_addmergepullsubscription_agent (Transact-SQL) to create the job under which the Merge Agent runs at the Subscriber.

  • sp_addlogreader_agent:

    You should now execute sp_addlogreader_agent (Transact-SQL) to manually add the job and supply the Windows credentials under which the Log Reader Agent runs at the Distributor. In versions of SQL Server before SQL Server 2005, this was done automatically when a transactional publication was created.

  • sp_addqreader_agent:

    You should now execute sp_addqreader_agent (Transact-SQL) to manually add the job and supply the Windows credentials under which the Queue Reader Agent runs at the Distributor. In versions of SQL Server before SQL Server 2005, this was done automatically when a transactional publication that supported queued updating was created.

In the security model introduced in SQL Server 2005, replication agents always make connections to the local instance of SQL Server with Windows Authentication using the credentials supplied in @job_name and @job_password. For information about the requirements of Windows accounts used when running replication agent jobs, see Replication Agent Security Model.

Security noteSecurity Note

When possible, prompt users to enter security credentials at runtime. If you store credentials in a script file, ensure that the file itself is secured.

To upgrade scripts that configure a snapshot or transactional publication

  1. In the existing script, before sp_addpublication (Transact-SQL), execute sp_addlogreader_agent (Transact-SQL) at the Publisher on the publication database. Specify the Windows credentials under which the Log Reader Agent runs for @job_name and @job_password. If the agent will use SQL Server Authentication when connecting to the Publisher, you must also specify a value of 0 for @publisher_security_mode and the SQL Server login information for @publisher_login and @publisher_password. This creates a Log Reader Agent job for the publication database.

    NoteNote

    This step is only for transactional publications and is not required for snapshot publications.

  2. (Optional) Before sp_addpublication (Transact-SQL), execute sp_addqreader_agent (Transact-SQL) at the Distributor on the distribution database. Specify the Windows credentials under which the Queue Reader Agent runs for @job_name and @job_password. This creates a Queue Reader Agent job for the Distributor.

    NoteNote

    This step is only required for transactional publications that support queued updating subscribers.

  3. (Optional) Update the execution of sp_addpublication (Transact-SQL) to set any non-default values for parameters that implement new replication functionalities.

  4. After sp_addpublication (Transact-SQL), execute sp_addpublication_snapshot (Transact-SQL) at the Publisher on the publication database. Specify @publication and the Windows credentials under which the Snapshot Agent runs for @job_name and @job_password. If the agent will use SQL Server Authentication when connecting to the Publisher, you must also specify a value of 0 for @publisher_security_mode and the SQL Server login information for @publisher_login and @publisher_password. This creates a Snapshot Agent job for the publication.

  5. (Optional) Update the execution of sp_addarticle (Transact-SQL) to set any non-default values for parameters that implement new replication functionalities.

To upgrade scripts that configure a merge publication

  1. (Optional) In the existing script, update the execution of sp_addmergepublication (Transact-SQL) to set any non-default values for parameters that implement new replication functionalities.

  2. After sp_addmergepublication (Transact-SQL), execute sp_addpublication_snapshot (Transact-SQL) at the Publisher on the publication database. Specify @publication and the Windows credentials under which the Snapshot Agent runs for @job_name and @job_password. If the agent will use SQL Server Authentication when connecting to the Publisher, you must also specify a value of 0 for @publisher_security_mode and the SQL Server login information for @publisher_login and @publisher_password. This creates a Snapshot Agent job for the publication.

  3. (Optional) Update the execution of sp_addmergearticle (Transact-SQL) to set any non-default values for parameters that implement new replication functionalities.

To upgrade scripts that add subscriptions to a merge publication

The following is an example of a SQL Server 2000 script that creates a transactional publication for the Product table. This publication supports immediate updating with queued updating as failover. Default parameters have been removed for readability.

USE [Northwind]

DECLARE @article AS sysname
SET @publication = N'NwdProductTran'
SET @publicationDB = N'Northwind'
SET @article = N'Products'

-- Enable the replication database.
EXEC sp_replicationdboption 
    @dbname = @publicationDB, 
    @optname = N'publish', 
    @value = N'true'

-- Add the transactional publication.
EXEC sp_addpublication 
    @publication = @publication, 
    @sync_method = N'native',
