Roles of RAP Components

All high availability requirements are met through the configuration of installed RAP components.

Install and run all primary software components (Event Stream Processor, RAPCache, and RAPStore) on their own hardware and network. Install and run all secondary software components (Event Stream Processor and RAPCache) on their own hardware and network. Primary and secondary software components must run on separate hardware and networks.

• RAPCache Database
  If high data availability is required for the RAPCache (Adaptive Server Enterprise), install and configure a secondary RAPCache.
• RAPStore Database
  Since the RAPStore (historical database) may save and maintain several years worth of market data, a redundant configuration is not practical.
• Event Stream Processor
  To have RAP running in a high availability environment, install and configure a primary and secondary instance of Event Stream Processor.
