If high data availability is required for the RAPCache (Adaptive Server Enterprise), install and configure a secondary RAPCache.
The RAPCache failover strategy requires a secondary installation of Adaptive Server Enterprise to complement the secondary configuration of Event Stream Processor.
If high availability is required for the RAPCache, a secondary RAPCache must be available. During normal operations, both RAPCaches contain the same data.
The primary instance of the RAPCache is installed and runs on a single host, while the secondary RAPCache is installed and runs on a separate host, that ideally uses a separate network.
