Installing Historian in a Cluster Environment

About this task

Historian works with Microsoft Cluster Service Manager to ensure high availability of the Historian server. If the primary Historian node in the cluster experiences difficulties, Historian is automatically started on another node to take over. Server high availability is managed through the Microsoft Cluster Service Manager.

Before you begin

  • Configure a failover cluster in the Windows server.
  • To use Historian Alarms and Events in a cluster environment, select the appropriate SQL server for both the cluster nodes.


  1. In Windows, go to All Programs > Administrative Tools > Failover Cluster Manager on any of the cluster nodes and make it the primary node.
  2. Install Historian on that node.
  3. Change the Historian Data path to the Cluster Shared Disk.
  4. Enter valid SQL Server details.
  5. Complete the Historian installation.
  6. After installing Historian on Cluster Node1, repeat steps from 1 to 5 for the remaining nodes.
