Title: DATA SYNCHRONIZATION METHOD, APPARATUS, AND SYSTEM
Abstract:
The present invention provides a data synchronization method, apparatus, and system. A primary master control unit receives application state data sent by a service processing unit, the primary master control unit modifies the application state data to non-synchronized state data, and the primary master control unit synchronizes the non-synchronized state data to the service processing unit; the primary master control unit modifies the non-synchronized state data to synchronizing state data, and the primary master control unit synchronizes the synchronizing state data to a standby master control unit; and the primary master control unit receives an acknowledgement message, the acknowledgement message comprising an acknowledgement content indicative of that the standby master control unit modifies the synchronizing state data to synchronized state data, the primary master control unit modifies the synchronizing state data to the synchronized state data, and the primary master control unit synchronizes the synchronized state data to the service processing unit. The problem of abnormal failure caused by data non-synchronization is resolved, the consistency of all unit data is achieved, and the maintenance cost is reduced.
