Configure Load Balancing and Failover

You configure load balancing and failover to spread requests over multiple servers, and to provide for redundancy if the primary directory connection becomes unavailable.

To configure load balancing and failover

1. Click Configure in the Directory Setup group box.

   The Directory Failover and Load Balancing Setup pane opens. The primary user directory opens in the Failover Group.

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

2. Enter the host name and port of the server to which the Policy Server should failover.

   Note: If you do not specify a port number, the Policy Server uses the default port. The default port for SSL is 636. The default port for non-SSL is 389.

3. Repeat steps two and three to define additional failover servers.

   Note: If you specify a port for the last server, but do not specify a port for any other servers in the group, the Policy Server uses the specified port for every server in the group.

4. Click Add Load Balancing.

   A new Failover Group opens.

5. Enter the host name and port of the server to which the Policy Server should load balance.

   Note: You can add the same server multiple times for load balancing, which forces more requests to be serviced by a specific system. For example, consider two servers in a group: Server1 and Server2. Server1 is a high-performance server and Server2 is a lesser system. You can add Server1 to the load balancing list twice so that it will process two requests for each request processed by Server2.

6. Repeat steps five and six to define additional load balancing servers.
7. Click OK.

   The User Directory pane opens. The Server fields lists the servers designated for failover and load balancing. A space separates each server designated for failover. A comma (,) separates each server designated for load balancing.
