Configure Policy Server Clusters for a Host Configuration Object

You can configure multiple Policy Servers in a cluster for failover operation. Clustering servers enables failover from one group of servers to another group.

Policy Server clusters are defined as part of a Host Configuration Object. When a SiteMinder Web Agent initializes, the settings from the Host Configuration Object are used to setup communication with Policy Servers.

Note: The following procedure assumes you are creating a new object. You can also copy the properties of an existing object to create an object. More information exists in Duplicate Policy Server Objects.

To configure a cluster

1. Click Infrastructure, Hosts.
2. Click Host Configuration, Create Host Configuration.

   The Create Host Configuration pane opens.

3. Verify that Create a new object is selected, and click OK.

   The Create Host Configuration: Name pane opens.

   Note: Click Help for descriptions of settings and controls, including their respective requirements and limits.

4. Type the name and a description of the Host Configuration object in the fields on the General group box.
5. Specify the Host Configuration settings in the fields on the Configuration Values group box.
6. Click Add on the Clusters group box.

   The Add Cluster group box opens.

7. Type the IP address and port number of the Policy Server that you are adding to the cluster in the Host and Port fields, respectively, on the Add Cluster group box.

   Note: To add another Policy Server to the cluster, click Add to Cluster. To delete a Policy Server from the cluster, click the minus sign to its right. To change the sequence of Policy Servers in the cluster, click the up and down arrows.

8. Click OK.

   The cluster is added to the Clusters group box.

   Note: To modify a cluster, click the right-facing arrow to its left. To delete a cluster, click the minus sign to its right. To add another cluster, click Add on the Clusters group box, and repeat steps 7 and 8.

9. Type a percentage in the Failover Threshold Percent field on the Clusters group box.

   Note: If the percentage of active servers in a cluster falls below the specified percentage, the cluster fails over to the next available cluster in the cluster list.

10. Click Submit.

    The Create Host Configuration task is submitted for processing.

    Important! The Configuration Values group box specifies a single Policy Server and a simple failover operation that are only used when no clusters are specified in the Clusters group box. If you decide to delete all clusters in favor of a simple failover operation, be sure to delete all Policy Server information from the Clusters group box.
