Self-Management of COTS Component-Based Systems Using Wrappers

This paper describes an approach to designing COTS (commercial off-the-shelf) components-based software system in which each COTS component is self-managed by a wrapper to improve dependability of systems. The wrapper for self-managing a COTS component detects the anomalies of the component; it reconfigures the anomalous component at run-time; and it repairs the anomalous component. The wrappers co-operate to each other to reconfigure COTS components, so that they make the system more reliable. The approach suggested in this paper is applied to the distributed elevator system with multiple elevators
