摘　　要：软件老化现象是影响软件可靠性的重要因素,长期运行的软件系统存在软件老化现象,这将影响整个业务系统的正常运行,给企事业单位带来无可估量的经济损失。软件老化出现的主要原因是操作系统资源消耗殆尽,导致应用系统的性能下降甚至崩溃或宕机。文中监测J2EE应用服务器系统资源的使用情况,考虑外界的负载变化,检测系统中软件老化现象,分析系统资源消耗何时达到临界值,从而帮助软件工程人员及时采取预维护手段,预防运行时系统中重大故障的发生。Software aging phenomenon plaguing in many long-running software systems is a contributing factor to impact software relia-bility and it will affect the normal operation of the whole service system and bring immeasurable economic loss to the enterprise. Software aging is characterized by progressive performance degradation or a sudden hang/crash in long-running software system due to resource exhaustion of operating system. In this paper,through monitoring system resource usage and considering system load variation,the soft-ware aging phenomenon in a J2EE application server is investigated to analyze when resource usage reaches the pre-determined thresh-old. Thus it will help software engineer take measures with preventive maintenance,and prevent the unplanned and expensive future sys-tem failures.
