During a server restart after a planned or unplanned shutdown, or during HA failover, a significant portion of time is spent on database recovery. Faster recovery minimizes database downtime. The goal of fast recovery is to:
Enhance the performance of database recovery
Recover multiple databases in parallel by making use of available server resources and tuning them intelligently
Provide multiple checkpoint tasks at runtime that can run concurrently to minimize the work at recovery time
