METHOD FOR DYNAMIC DATA SYNCHRONIZATION BETWEEN DUAL-ACTIVE SYSTEMS

摘要

Provided in the present invention is a method for dynamic data synchronization in primary/ standby dual-active systems. Said primary/ standby dual-active systems comprise a primary system and a standby system, both capable of becoming either a source end or a destination end. The method comprises the following steps: the source end packs, according to a local data synchronization request, data requiring synchronization and corresponding information into a synchronization data packet; the source end transmits, according to a predetermined communication method, the synchronization data packet to the destination end; the destination end unpacks the synchronization data packet upon reception and performs data update operations according to said information. Said local data synchronization request is an operation request that comes from the access node of the primary system or the standby system and causes a data change. The method has little impact on the primary and standby systems when synchronizing data, making the method suitable for applications of dynamic data synchronization in primary/standby dual-active systems.
