This paper describes the consistency in the self-reconfiguration of component-based self-healing systems against anomalous objects in the components. A self-healing component is structured into different types of objects. When a self-healing component meets some faults, it self-reconfigures objects by isolating anomalous objects from healthy objects within the component. The self-reconfiguration may cause a component to be inconsistent due to anomalous objects. This paper describes an approach to establishing consistency at runtime in the self-reconfiguration of component-based self-healing systems. Self-healing components remains consistently in the self-reconfiguration by rolling back an inconsistent state to a consistent state. For this, objects in self-healing components are designed to support the consistency of self-reconfiguration.
