RAPCache failover strategy requires a secondary installation of ASE to complement the secondary configuration of the RAPCache Subscriber.
A RAPCache is always associated with a Subscriber. The primary Subscriber for the RAPCache has a corresponding RAPCache installed and configured. If high data availability is required for the RAPCache, a secondary RAPCache is installed and configured. During normal operations, both RAPCaches contain the same data
The Subscriber/RAPCache pair for the primary data stream is installed and run on a single host, while the Subscriber/RAPCache pair for the secondary data stream is installed and run on a separate host, preferably using a separate network.
