Web应用服务器OnceAs的实现与测试

The implementation and test of the web application server OnceAs

OnceAs是网驰(ONCE)软件基础平台的一个核心部分,基于J2EE1.3规范进行设计和开发,实现J2EE规范中约定的接口和服务,目前OnceAs提供标准版和集群版两个版本,可运行于多个异构操作系统,支持多种数据库管理系统。OnceAs已通过SUN JPS的所有功能测试,并在高端的PC机或低端的服务器上就可以达到J2EE应用服务器性能测试基准ECperf所要求的各项性能指标。本文介绍OnceAs的系统结构,各主要功能模块、服务和工具的实现方式,并通过Ecperf测试描述了OnceAs的各项主要性能。

OnceAs is one of the core parts of ONCE Software Platform. It was designed and developed based on the J2EE standard. OnceAs has provided two versions, namely standard version and cluster version, both can run on different operation systems, and support multiple database management systems. It has passed all func- tional tests of SUN JPS, and achieved every functional target required by the J2EE application server functional test standard ECperf on either the high-end PC machines or the low-end servers. This paper introduces the systemic structure and the mode of every main functional modules, services and tools. Eventually, it describes every primary performance of Once.As through the ECperf tests.
