一种改进的分布式并行事务处理策略研究

目前,XML技术在基于因特网的复杂分布式系统事务处理中的应用已成为国内外研究的热点,尤其是如何提高分布式系统的并行事务处理能力,同时使系统具有高度容错能力,是一个具有挑战性的课题。本文提出了一种对XML文档进行DOM树划分、将复杂长事务划分成可并行执行的子事务的并行事务处理策略,从而在不影响其容错性能的情况下进一步提高分布式系统的并行运算性能和处理复杂长事务的能力,同时做到负载均衡。

An Enhanced Strategy of Distributed Parallel Transaction Processing Based on CORBA

At present, XML has become a hotspot in the application of the complicated distributed transaction processing. Especially it is really challenging in  the aspect of how to improve the ability of distributed parallel transaction processing and make the system support fault tolerance. We propose an enhan ced strategy of distributed parallel transaction pro- cessing which divides the XML. documents, and divides the long-run transactions into parallel sub-transactions. With this strategy, we can improve the distributed systemS s capability of parallel operation and long-run transaction processing, and make the overloads balanced.
