Abstract

Autonomic computing aims to make self-healing, self-tuning,self-configuring and self-protecting systems a reality.This self-adaptive behaviour is achieved by carryingout changes upon a system when particular constraints orrequirements are not met. Existing work focuses on how todetermine when a change is necessary and what that changewill be. We argue that the mechanism used to carry out thechange is equally important and can determine if the changeheals, tunes or protects the system as it was intended to.We present OpenRec, a framework which facilitates autonomiccomputing where the change mechanism is also self-adapting.Novel features of our work include a clean separationof concerns in the self-adaption process, support foran extensible set of change mechanisms and the use of anevolving knowledge base which guides the change process.
