异步通讯的J2EE系统的性能优化研究

随着异步通讯和企业级开发平台诸如J2EE的普及和发展,越来越多的企业级应用采用了这些技术作为快速开发平台.但是同时,这些应用也面临着一些困扰,特别是性能问题.这主要是由这些系统的分布式、复杂性和数据无关性引起的.讨论了这些问题,并且通过改善消息服务器配置和分布式系统资源的事务提交策略来避免性能瓶颈的出现.用一个在金融领域里的例子来阐述事务的提交策略是怎么影响这类企业级应用性能.

Research of performance optimization of J2EE application with asynchronous messaging

With the popularization and development of asynchronous messaging and enterprise platform such as J2EE, more and more enterprise applications apply these technologies and take them as a solution for the development of platform. Meanwhile, it also meets some problems for these applications especially the performance issues. It is mainly because of the distribution, complexity and data- insensitive of these applications. These problems how to avoid and solve the bottleneck of performance are discussed by messaging pro- vider configuration and transaction commit strategy. A realistic example that is supposed to happen in financial service is given to illustrate how the transaction strategy affects the performance of these applications.
