摘　　要：详细分析了分布式实时事务的提交处理模型。首先分析了传统分布式提交协议在实时环境中的缺陷。然后介绍了一种专门为实时环境开发的分布式提交协议PROMPT。在此基础上,提出用一阶段协议取代PROMPT中二阶段协议的设计构思,并详细分析了这种优化对提交处理过程的各种影响。The commit processing model in the distributed real-time transactions is investigated in detail. The inadequacies in the traditional distributed commit processing protocols are described. A new distributed commit processing protocol, PROMT, specifically designed for the real-time domain is given. To improve the performance of the commit processing a new design incorporating the IPC protocol with the PROMPT is presented. The impact of this optimization on the commit processing in the distributed real-time transactions is analyzed.
