摘要： 本文讨论了分布式数据库的一种死锁检测方法,称为定向迭代法。用分布式算法与等待图相配合来检测死锁,同时在实现机制中附加延迟检测以判断是否真假死锁。

Abstract: In this paper, we discuss one of the approaches used, to detect dead lock in DDE, which is called?directive iteration method. This approach combines the distributed algoritgm with wt,Jof graphs to detect dead-lock. It also has delay-detection in its implementation mechaB?;tn to order to determine if a deadlock is true or not.
