Administrative UI High Availability

Install more than one Administrative UI to be sure that unexpected outages do not prevent you from managing SiteMinder objects. Consider the following before installing another Administrative UI:

• Register the Administrative UI with a Policy Server that is not already sharing a trusted connection with an Administrative UI. Registering with another Policy Server prevents a single Policy Server outage from disabling both GUIs.
• An Administrative UI cannot failover to multiple Policy Servers. However, you can configure the Administrative UI to manage multiple Policy Servers.
• If the existing Administrative UI is configured for external SiteMinder administrator authentication, configure the new Administrative UI with the same external store. Configuring the new Administrative UI with the same external store helps ensure that all SiteMinder administrators are available to all GUIs.

Note: For more information about configuring an external administrator store, see the Policy Server Configuration Guide.
