To improve availability of each individual service, we propose a runtime configurable fault management mecha nism (FMM) which detects deviations from given service specifications by intercepting interface calls. When repair is necessary, FMM picks a repair action that incurs the best tradeoff between the success rate and the cost of repair. Considering that it is rather difficult to obtain sufficient in formation about third party components during their early stage of usage, FMM is designed to be able to accumulate knowledge and adapts its capability accordingly.
