Abstract: Middleware resource management is a critical technology to guarantee the performance of Web applications. However， the two main views of resource management， which are system-driven and business-driven， have not been unified conceptually. Most of the middleware resource management technologies focus on specific resource， and are difficult to come into being holistic resource management optimization. This paper proposes a hierarchical middleware resource model and coordinates the system-driven and business-driven resource management views by utility functions. The formed middleware resource management framework is called OnceRMF， and the results of simulation experiments have shown its effectiveness.

Key words: middleware, resource management, utility

摘要： 中间件资源管理是保障Web应用性能的重要手段，然而目前系统驱动和业务驱动两种主要的资源管理视角没有在概念上取得统一，相关研究成果主要针对特定的资源，难以实施整体性的资源管理优化。针对中间件资源特征提出了一种层次化的中间件资源空间模型；通过效用函数实现系统驱动与业务驱动的协同资源管理，形成了一种效用驱动的中间件资源管理框架OnceRMF。通过仿真实验结果验证了OnceRMF的有效性。
