  1. Configure Microsoft (MS) Cluster Server in an Active-Passive cluster environment (2-node cluster).

  2. Install Microsoft SQL Server using the New SQL Server Failover Cluster Installation option (single-node) on Cluster Node 1 computer using SQL Server Setup.

  3. Install Microsoft SQL Server using the Add node to a SQL Server Failover Cluster option on Cluster Node 2 using SQL Server Setup.

Install and Configure CampusNexus CRM

Note: In the testing environment, Application Server, Client, and Data Management Utility are installed outside the Cluster environment.

To install CampusNexus CRM, perform the following steps:

  1. Install the Main database, Distributor database, and all Subscriber databases on the Primary Node of MS Cluster Server.

  2. Provide the path of the Cluster Disk for the target and backup folders of the Database component during installation.

  3. Restart the Primary Cluster Node.

  4. Ensure that all Cluster Resources are assigned to the Primary Node after the computer is restarted.

  5. Install Application Server on a computer that is outside the Cluster environment.

  6. Install all CampusNexus CRM components across multiple computers outside the Cluster Server.

Notes:

  • It is not mandatory to install Distributor and Subscriber databases in a clustered environment.

  • Every time the Primary Cluster Node is restarted, it is mandatory to assign all Cluster Resources to the Primary Cluster Node.

To configure CampusNexus CRM on the Secondary Cluster Node, perform the following steps:

  1. Shut down the active Cluster Node.

  2. Enter the Failover Node on the Cluster Node field and then install.

Notes:

  • Ensure that the registry information on the Primary Cluster and Secondary Cluster Nodes is identical.

  • The installation of the Failover Node needs to be done after the installation of all other CampusNexus CRM components is completed.

 

Simulate a Resource Failure

You can simulate the failure of a Resource and verify its status on the Primary Cluster Node. Further, you can verify if the failed Resource starts automatically on the Secondary Cluster Node.

To simulate the failure of a service, perform the following steps:

  1. Open the Failover Cluster Manager on the Primary Cluster Node. For steps to open the Failover Cluster Manager, see Open and View the Failover Cluster Manager. All available Resources are displayed in the right pane.

  2. Right-click a Resource and select More Actions, Simulate failure of this resource.
