摘　　要：针对网格中资源利用率低下,单一、集中的资源监控面临单点失效、性能瓶颈等问题,引入一种教育资源网格体系结构模型,给出一种资源监控机制。该机制采用层次化、分布式按域管理思想,融合JNI、Web服务、目录服务等技术,通过构建其总体框架及逻辑结构,说明资源的远程注册、发现及动态加入/离开资源节点的检测的监控管理的过程。通过性能分析表明,该机制安全、可靠、有效,能满足教育资源网格的应用需求。According to the fact that the resources utilization is low in the grid, moreover, single point expiration and performance bottleneck problems are caused by sole and the centralized resources monitoring, etc, this paper introduces an educational resources grid architecture model and gives a resource monitoring mechanism. This mechanism employs the thought of hierarchical and distributed management according to domain which fnses the technologies of Java Native Interface（JNI）, Web services and directory services. Through the construction of its overall frame and the logical organization, it shows the monitoring management process of the resources long-distance registration, the discovery and the resources point examination which can join/leave dynamically. The performance analysis indicates that the mechanism is safe, reliable and effective. It can meet the application demand of the educational resources grid.
