6 Steps to setting up Replication with Mirroring

,

I spent hours looking for information on how to setup transactional replication with updatable subscribers while also using database mirroring. I found some articles that were very helpful but also very confusing.

 

In the provided script I describe the six steps to successfully setup replication when using mirroring. I like to split the script up into six independent scripts so I can run each of them on the proper servers, so that is where I would start. Once you determine which servers are your distributor, your principal publisher, your mirror publisher and subscriber, the comments section of each script will help you determine where to run them. Just be sure to pay special attention to the variables in each script so you can insert your own values. And as always, you should be aware of the potential performance impact of starting the initial snapshot in production during business hours.

 

FYI: The script assumes that you already have mirroring setup properly and have tested failover.

/******************************************************************************
1. Setup Distribution on Distributor

!!!!!!!!RUN ONLY ON THE DISTRIBUTOR!!!!!!!!

Use this script on the distributor to setup distribution and add publishers.

Replace the value in @distributor to the name of the distributor
Replace the value in @password to the password you will use to allow publishers
Replace the value in @database to the distribution database name
@security_mode: 1 = Windows Authentication, 0 = SQL Server
Replace the value in @publisher with the name of the publisher you will setup
Replace the value in @distribution_db to the distribution database
*******************************************************************************/

--sets up distributor with remote setup password
use master
exec sp_adddistributor @distributor = N'distserv', @password = N'password123';
GO

--sets up the distribution database name to be used with Windows Auth
use master
exec sp_adddistributiondb @database = N'distribution', @security_mode = 1;
GO

--adds an authorized principal publisher that will use Windows Auth
use distribution
exec sp_adddistpublisher @publisher = N'pubserv', @distribution_db = N'distribution', @security_mode = 1;

--adds an authorized mirror publisher that will use Windows Auth
use distribution

GO

2. Setup Remote Distributor on the Publisher

!!!!!!!!!!RUN ON PRINCIPAL AND MIRROR!!!!!!!!!!

Use this script on the publisher to add the remote distributor.
Replace the value in @distributor to the name of the distributor.
Replace the value in @password to the password setup on the remote distributor.

3. Create Publication on Publisher

!!!!!!!!!!SHOULD ONLY BE RUN ON THE PRINCIPAL!!!!!!!!!!!!!

This script will create a new publication and add all articles below. You only need to do this on the 
principal publisher because it will be transfered to the mirror publisher during a mirror failover.
Replace the value in @dbname with the database you will be publishing
Replace the value in @publication with a name for your publication
Replace the value in @description with any description you would like to give
The value in @alt_snapshot_folder should be set to the value of the snapshot folder setup on the distributor
Replace the value in @article with a new article name of your choosing
Replace the value in @source_object with the logical name of the article (table, view, etc.)
Replace the value in @destination_table with the table name on the subscriber
Replace the value in @subscriber with the name of the subscriber server
Replace the value in @destination_db with the name of the database on the subscriber
Be sure to replace instances of 'mydatabase' with the appropriate values of your database
