【摘要】 J2EE应用服务器基于JCA规范为企业资源系统提供了一个统一的资源集成解决方案。在JCA框架下,应用服务器提供连接管理、事务管理及安全管理等服务,这些服务是影响系统性能的重要因素。本文主要研究了应用服务器端在支持资源集成中与性能相关的几个关键问题,包括连接池管理和事务管理,提出了行之有效的优化策略。本文的工作已经应用到中科院软件所自主开发的J2EE应用服务器OnceAS中,取得了很好的效果。更多还原

【Abstract】 Based on JCA specification, J2EE Application Server gives a standard way to integrate enterprise re- sources. Under the connector architecture, the application server provides different services, including transactions, security and connection management for resource adapters, and these services are important to the system perfor- mance. This paper studied several problems in application server’s resource integration implementation, including connection management and transaction management. Some available optimizations and the implementations are giv- en. These optimizations have been successfully employed in the J2EE Application Server OnceAS.更多还原
