分布式数据库死锁检测协议

On Protocols for Deadlock Detection in Distributed Database Systems

分布式数据库死锁检测算法主要分为集中式、层次式和分布式。

Deadlock detection algorithms of distributed database can be classified into centralized , layered and distributed .

面向对象数据库死锁检测方法研究以实例描述分布式事务处理、分布查询等。此外本文还详细介绍了分布式死锁检测算法和假死锁以及解决方法。

RESEARCH OF AN ALGORITHM FOR DETECTING DEADLOCK IN OODBMS BASED ON NESTED TRANSACTION MODEL And then describe distributed Transaction Process and distributed query , etc.

同时，现有的分布式数据库死锁检测算法通常假设系统采用排它锁模式或共享/排它锁模式，而忽略了分布式数据库系统中普遍应用的多锁模式，使得算法无法有效应用于分布式数据库系统。

Moreover , because existing deadlock detection algorithms of distributed database commonly adopt X lock mode or S / X lock mode , and lose sight of multiple lock mode which is applied widely in distributed database systems , these algorithms can not be applied availably in distributed database systems .
