基于分桶算法的灾备数据比对工具研究与实现

Research and Implementation of Bucket Algorithm Based Disaster Recovery Data Comparison Tool

随着国家电网公司信息化建设的快速推进,其生产、经营和管理对信息系统愈加依赖。为确保信息系统安全稳定运行,国家电网公司在北京、上海、西安三地建成灾备中心并正式投运,而利用有效的工具验证灾备数据与生产数据的一致性,是确保灾备效果的核心工作。文章主要对数据一致性验证工作的背景、现状、目标及意义进行了阐述,并在对数据比对的核心算法进行深入研究的基础上,提出了数据比对工具的实现方式。

With the rapid development of the informatization construction in the SGCC, the dependency on inlbrmation systems for production. operation and management is increasing. In order to ensure intbrmation system operations safe and stable, three disaster recovery centers in Beijing, Shanghai, Xi＇an have been built and put into operation. To validate the consistency of the disaster recovery data and production data using efficient tools has been a core work to ensure disaster recovery effect. This paper presents situations, goals and meanings of the data consistency validation tool, studies the core algorithms of data comparison deeply, and proposes an implementation method of the data comparison tool.
