To upgrade Remedy SSO in a HA environment using the Remedy installer silently

Note

The Remedy SSO Admin UI requires sticky session/Session Persistence in an HA environment. Usually, this is accomplished by enabling sticky session/Session Persistence on the load balancer. Different load balancers have different configurations to enable a sticky session/Session Persistence. Refer to the specific load balancer documentation or ask the vendor for details about the configuration.

Note that when sticky session/Session Persistence is not enabled for the Remedy SSO Admin UI, the admin user behind the firewall can use a specific Remedy SSO server hostname to access admin UI instead of using the load balancer URL.
