摘要
1.引言
在计算机应用领域,存在一类应用,要求系统满足一定的实时性要求,较高的性能,较好的容错能力.这类应用的一个重要特征就是业务关键(mission critical),所涉及的数据量大,比如电信计费、军事指挥控制、银行业务处理等等.
For some certain applications. they require massive application data to be resident in main memory- We categorize the exceptional data resided in memory based on the analysis of corresponding reasons. Exploiting mature CRC technologies to build a redundancy code for each data unit in memory to achieve integrity and combining traditional log and checkpoint technologies, we present the basic methods of prevention for corrupted data propagation and directly static detection and recover of corrupted data.
