In order to enlarge the field of application, reduce the cost of software rejuvenation and improve software availability and reliability,the adaptive software rejuvenation with fine rejuvenation granularity of object-oriented software system would be put forward. Based on the characteristics of the component and coupling relation between the components of the system, this paper determines the finest rejuvenation granularity, analyzes the degree of the coupling relation,sets down a method to calculate the restart dependence and its degree of the components,so that determines the restart reachable set of each component and gets the restart gather of the components at every granularity,and finally sets down and models the adaptive nested software rejuvenation policy. So executing intelligent software rejuvenation at fine rejuvenation granularity in the object-oriented software system can be supported.
Keywords： software rejuvenation restart dependence restart reachable set rejuvenation granularity SHLPN
