Cluster the BizTalk Server Databases
This section provides guidelines for deploying a Microsoft BizTalk Server solution with high availability. If the BizTalk Server databases become unavailable, the BizTalk Server environment will not function correctly. To provide high availability, you can create a Microsoft SQL Server cluster for the BizTalk Server databases, as shown in the following figure.
To provide high availability for the BizTalk Server databases, you must have at least two computers that are running SQL Server and a shared disk array for use by a Windows Server Failover Cluster.
Procedures for Clustering the Databases
Before you start
When you create the domain groups for your BizTalk Server environment, you must create Active Directory domain global groups.
Configure the SQL Server cluster before you install and configure BizTalk Server. For more information about clustering SQL Server, see Always On Failover Cluster Instances.
If you are also clustering the master secret server, configure that server first. For more information about high availability for Enterprise Single Sign-On, see High Availability for Enterprise Single Sign-On.
To run the BizTalk Server Configuration Wizard
Install BizTalk Server on a runtime server.
Launch the BizTalk Configuration Program. Click Start, point to All Programs, click Microsoft BizTalk Server 20xx, and then click BizTalk Server Configuration.
Follow the steps in Import and Export BizTalk Server Configuration to apply a custom configuration. To specify the SQL Server cluster for the BizTalk databases, enter the name of the SQL Server cluster in the Databases dialog of the configuration program as described in the Editing Databases section of this topic.
Complete the BizTalk Server configuration by following the instructions in Configure BizTalk Server.
