Disaster Recovery Prerequisites

The disaster recovery feature depends on appropriate physical infrastructure, realm configuration, and running processes.

To use the disaster recovery feature of TIBCO FTL, you must satisfy these requirements:

• Equivalent Hardware Outfit the disaster recovery site with hardware equivalent to equipment at the main site.
• WAN Capacity Link the two sites with sufficient bandwidth to replicate persistence data in real time, even during periods of peak volume. It is good practice to link the sites with redundant WAN lines for fault tolerance.
• Parallel Families of FTL Servers Run an equivalent set of FTL server processes at each site.
• Parallel Sets of Persistence Services Configure an equivalent set of persistence services at each site. Clients connect only to services in the primary set at the main site. Standby services at the disaster recovery site replicate data, but clients do not connect to them during normal operation.
• At both sites, you must configure the persistence services in separate auxiliary servers, and not in the core servers.
