Abstract
Self-management is a key feature of autonomic systems. This often demands the dynamic reconfguration of a distributed application. An important issue in the reconfguration pro- cess is the strategy that is used to coordinate the multiple participants involved in the reconfguration. This paper ad- dresses the problem of providing support for multiple recon- fguration strategies in autonomic systems that are designed as self-reconfgurable service compositions. We decompose existing strategies in two separate aspects | an orchestra- tion protocol and a local reconfguration procedure. This separation allowed us to design a set of generic pluggable components that can be integrated in concrete service com- positions, in order to support different strategies. The strat- egy selection is performed according to the semantics of each reconfguration. To illustrate our approach, we have imple- mented an instance of these pluggable components for the RAppia composition framework.
