摘　　要：MIDAS是为开发多层分布式应用系统提供的一个中间透明引擎,而多层分布式系统的一个关键问题是容错.文章讨论了数据更新错误、单台应用服务器故障、多台应用服务器故障3种情况下的容错处理机制并给出了相应的实现算法.MIDAS is a middle transparent engine provided for empoldering multi-tier distributed application system, and fault-tolerance is a key problem to the multi-tier distributed system. If the problem of fault-tolerance isn＇t resolved commendably,multi-tier distributed application system won＇t work stably and unfaihngly. In this paper, fault-tolerance processing mechanism in three different instances are discussed,and some relevant arithmetic are listed.
