发明名称 REDUCING LIKELIHOOD OF DATA LOSS DURING FAILOVERS IN HIGH-AVAILABILITY SYSTEMS
摘要 A method, system, and computer program product for reducing likelihood of data loss during performance of failovers in a high-availability system comprising a primary system and a standby system are provided. The method, system, and computer program product provide for defining a halt duration, periodically determining a halt end time, halting data modifications at the primary system responsive to failure of data replication to the standby system, resuming data modifications at the primary system responsive to a last determined halt end time being reached or data replication to the standby system resuming, and responsive to the primary system failing prior to a previously determined halt end time, determining that a failover to the standby system will not result in data loss on the standby system with respect to the primary system.
