This paper describes the self-healing mechanism for components in reliable systems. Each component in a self-healing system is designed as a layered architecture, structured with the healing layer and the service layer. The healing layer of a self-healing component is responsible for detection of anomalous objects in the service layer, reconfiguration of the service layer, and repair of anomalous objects detected. The service layer of a self-healing component provides functionality to other components, which consists of tasks (concurrent or active objects), connectors, and passive objects accessed by tasks. A connector supports the self-healing mechanism for self-healing components as well as encapsulates the synchronization mechanism for message communication between tasks in a component. Connectors are involved in detection of anomalous objects, reconfiguration of components, and repair of anomalous objects. This paper also specifies connectors - the message queue self-healing connector. message buffer self-healing connector, and message buffer and response self-healing connector - which provide functionalities for the self-healing mechanism.
