摘要
用超时来解决分布死锁问题的难点是难于确定一个合适的超时值。本文首先给出一类基于微机局网的分布式事务处理系统的构造模型,在对其分析的基础上提出了一个超时值的计算方法STEM,用它可在实际环境中以有限次数的统计试验确定超时值的近似最佳取值点。
The difficulty for using timeout mechanism to solve distributed deadlock problem is that it is hard to get an appropriate timeout value. According to the characteristics of microcomputer-based LAN, a model of distributed transaction processing system is presented. Based on this model, a statistical method for estimating timeout value is proposed, which can be used in real environment to gain an optimal timeout value through limited times of statistical test.
