Configure Clusters

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: For information about Host Configuration Objects, see the Web Agent Configuration Guide and the Policy Server Configuration Guide.

To configure a cluster

1. Select the Infrastructure tab.

   A list of tasks appears.

2. Select Agents, Create Host Configuration.

   The Create Host Configuration pane appears.

3. Select the Clusters tab.
4. In the Clusters group box, click Add.

   The Cluster Setup group box opens.

   Note: You can click Help for a description of fields, controls, and their respective requirements.

5. Enter the IP address and the port number of the Policy Server in the Host and Port fields respectively.
6. Click Add to Cluster.

   The Policy Server appears in the servers list in the Current Setup group box.

7. Repeat these steps to add other Policy Servers to the cluster.
8. Click OK to save your changes.

   Your return to the Host Configuration pane. The Policy Server cluster is listed in a table.

9. In the Failover Threshold Percent field, enter a percentage of the number of Policy Servers that must be active and click Apply.

   If the percentage of active servers in the cluster falls below the percentage you specify, the cluster fails over to the next available cluster in the list of clusters. This setting applies to all clusters that use the Host Configuration Object.

   Important! The Policy Server specified in the Configuration Values group box is overwritten by the Policy Servers specified in a cluster. This Policy Server is no longer used because a cluster is configured. For the value of the Policy Server parameter in the Configuration Values group box to apply, do not specify any Policy Servers in a cluster. If clusters are configured and you decide to remove the clusters in favor of a simple failover configuration using the Policy Server parameter in the Configuration Values group box, be sure to delete all Policy Server information from the cluster.
