摘要
分析了当前双机热备份系统设计中存在的问题，提出一种基于消息同步的双机热备份系统的实现方法，并对其中的关键技术作了介绍，该方法可以实现容错对上层业务的透明性和容错结构的动态性．
The problem encounted in the design of two-unit warm standby system is analyzed, and a method of implementing a two -unit warm standby system based on message synchronize is proposed.The method can make the function of fault tolerance being transparent to the service of high level.
