摘　　要：检查点机制作为一种软件容错机制 ,可以与新出现的广域分布式系统网格相结合 ,更好地满足网格系统的容错要求。文中详细分析了检查点回卷恢复协议的关键点 ,并对数据网格中GridCPRAPI进行了解析 ,提出一些改进 。Checkpointing is an important method for fault tolerance of software. It can be combined with wide area distributed system grid. Consequently it can be very effective for the fault tolerance demand of grid system. Checkpoint rollback recovery protocols in data grid is described in this paper, and grid API is also analyzed in detail. This paper also gives some proposes, which are more useful to improve fault-detection and fault tolerance in grid system.
