摘要
作为应用服务器重要组成部分的分布管理器主要用于提供分布环境下的事务处理能力,它的性能是制约应用服务器上分布事务吞吐能力的重要因素。讨论了在J2EE应用服务器框架下如何进行分布事务管理器的性能优化,同时给出了分布事务管理器ISTX的性能优化实现。实验数据表明,对ISTX的性能优化能在保证分布事务可靠性的前提下,较大幅度地提高了分布事务处理的性能。
As an important part of an application server, the distributed transaction manager mainly provides transaction processing ability in distributed environments, and its performance is one of the limitations against the throughput of distributed transaction processing software running on an application server. How to optimize the performance of a distributed transaction manager in the framework of J2EE application server is discussed, and the implementation of performance optimization on our distributed transaction manager ISTX is also presented. The experimental results show that the performance optimization on ISTX can greatly improve distributed transaction processing performance under the precondition of guaranteeing reliability.
