A Self-Healing Technique based on Encapsulated Operation Knowledge

Although autonomic computing reduces traditional operational cost, it introduces another cost factor related to operation knowledge. This paper focuses on self-healing functionality and proposes a technique which improves reusability of component-level operation knowledge for self-healing systems. Operation knowledge which attains reusability becomes independent of a specific system structure and therefore it can be reused across organizations and adapted to changes. To achieve reusability, operation knowledge is encapsulated in components whereas system specific information is excluded. To cope with the remaining problem of dependency among components, a dependency injection mechanism is introduced. The dependency injection mechanism works out needed recovery actions by relating component and system-specific information. Furthermore, this paper describes an implemented prototype together with an application example.
