自律计算的目的是使得IT系统能够在管理者的策略指导下实现自我管理,即实现自配置、自修复、自优化、自保护的自律计算特征。由于自律系统建立在分布式架构下,涉及的技术和标准较多,实现上较为困难,而现有的研究主要集中在如何使得产品具有部分的自律计算特征。因此,建立通用的具有应用价值的计算模型成为自律计算领域研究的一个重要课题。文章在研究了现有的自律计算模型的基础上,提出了一种适用于分布式环境的自律计算模型,对管理资源、资源操作、状态、动作等模型构成要素进行了形式化定义,从而大大增强了自律模型的应用范围和实用价值。
Current autonomic computing model can not be applied in the distributed environment,so we proposed a new model which is based on IBM basic model to solve the problem.First,we applied open standard-WBEM(Web-Based Enterprise Management) to the new model to solve the problem of communication between recourses in distributed environment.Then,we defined the essential elements in the new model based on WBEM,and designed the distributed model and policy model for resources management.Finally,according to the application in autonomic computing,we defined two operations to monitor system faults and send notification when error occurred.Autonomic computing system based on the new model has been applied in distributed environment,which can realize self-management.
