Abstract
This paper presents the common methods of remote data synchronization in computer information system.Under the large volume business scene of a transaction processing system,traditional data replication technology is limited by high network bandwidth.Therefore,we propose a real-time data synchronization method based on transaction message.The transaction messages of transaction processing system were classified as application level message redo logs,and the methods and strategies of packet decomposition and encapsulation,message synchronization and buffer pool management were adopted.Finally,the real-time synchronization target of business data was realized with very low line bandwidth.Through the implementation of disaster recovery case practice,we fully verified the feasibility and effectiveness of the method.The proposed method can significantly reduce the implementation cost of application-level disaster recovery in large traffic.关键词
