数据复制技术在铁路电子支付平台中的应用

Application of Data Replication Technologies in Railway Electronic Payment Platform

分析基于存储复制、基于逻辑卷(LV)复制、基于文件复制和基于事务复制等的数据复制技术及其优缺点。针对数据复制技术的选择进行调研和测试,选择采用Share Plex数据复制软件。分析Share Plex数据复制软件特点,从数据捕获、数据传输和数据应用方面论述数据复制过程。阐述和分析Share Plex数据复制软件在铁路电子支付平台数据容灾中的应用,为验证铁路电子支付平台数据库容灾系统的有效性,对其数据库容灾系统进行正反向切换演练。

This paper analyzes data replication technologies based on storage replication, logical volume （LV） replication, file replication and transaction replication, and their advantages and disadvantages. For choosing data replication technologies, researches and tests are carried out, and SharePlex data replication software is chosen and used. The paper analyzes the characteristics of the software and the data replication process from data capturing, data transmission, and data application. It also describes and analyzes the application of SharePlex data replication software in the data disaster tolerance of railway electronic payment platform. In order to verify the effectiveness of the disaster tolerance system of railway electronic payment platform database, forward and reverse switches of the system are carried out.
