摘要
在具体分析铁路客票系统备份及容灾手段现状的基础上,讨论基于Sybase的Warmstandby复制技术及全库复制技术实现的客票异地灾备系统,论述该系统的软硬件结构、设计思想、研究方法、复制策略的制订以及复制的性能优化策略。
The present status of the backup and disaster recovery methods of Railway Ticketing and Reservation System （TRS） were firstly analyzed. The TRS Remote Disaster Recovery System for railway station based on warmstandby technology of Sybase and whole database replication were proposed. The structure of hardware and software, design idea, research methods, replication strategy, performance optimization of Remote Disaster Recovery System for railway station TRS were discussed.
