It ensures that if the deployment container that runs Access Manager service becomes unavailable, the web agent still processes access requests through a secondary, or failover, deployment container running Access Manager service.

Setting up failover protection for the web agent, requires modifying the web agent configuration file. However, you must first install two different instances of Access Manager on two separate deployment containers.

Then follow the instructions in this guide to about installing the web agent. The web agent installation program prompts you for the host name and port number of the failover deployment container that you have configured to work with Access Manager. The following property in the web agent configuration file, stores the failover deployment container name:
