Abstract:
1. A method for automatically maintaining an autonomic computing system in a steady state, the autonomic computing system having a plurality of parameters, each parameter having one or more thresholds, the autonomic computing system having a plurality of influencers, adjustment of the influencers affecting values of the parameters, the method comprising: in response to determining that one or more of the parameters are each reaching one of the thresholds of the parameter, the one or more of the parameters referred to as to-be-affected parameters, wherein the influencers that are distinctly associated with the parameters are referred to as direct influencers, such that adjustment of each influencer affects the value of only one of the parameters, wherein the influencers that are indirectly associated with the parameters are referred to as meta influencers, the meta influencers organized over at least two levels including a first level and a last level, adjustment of each meta influencer at a first level directly affects one of the direct influencers, which in turn affects the value of one of the parameters, adjustment of each meta influencer at each level other than the first level directly affects one of the meta influencers at an immediately lower level; wherein, for each influencer, determining the correlation value between the influencer and each to-be-affected parameter comprises: and wherein adjusting one or more of the influencers so that the to-be-affected parameters return to more-normal values comprises:
