Self-healing is a way for tackling the ever increasing complexities to manage and fix manually computer software. This paper proposes a cellular adaptation inspired mechanism to make a component based distributed system self heal. In this mechanism components of distributed system are seen as cellules of body. Environmental changes in our body cause cellular adaptations; similarly, changes incomponents' environment cause system reconfiguration. Healing is done by healer components. Each node has one healer component that monitors components residing in that node. The system is monitored via monitoring messages that pass through components and it is adapted by reconfiguration. Components of system are considered as black boxes to keep the code of components intact even when they are self healed. The proposed mechanism is evaluated by running a scenario that is implemented in CORBA Component Model (CCM). The CCM is a serverside component model for building and deploying CORBA applications.
