Abstract:
Recently, there has been a considerable interest in both policy-based management and autonomicbased management for distributed systems. However, the dynamic unpredictable nature of distributed systems makes it difficult to predict the resolution strategy at runtime. This suggests, a need to develop a policy-based autonomic control service, which has the capabilities to perform system reconfigurations with minimum intervention from human users and without having to recode the software, shutdown, or disturb the system at runtime. In this paper we propose a control service, with autonomic capabilities, that is orchestrated by its policies (internal or external policies). The autonomic capabilities include: self-detection, selfdiagnosis, self-repair, and self-reconfiguration, which may be used to stabilize/correct the system in the event of conflicts/failures. In addition, the control service provides capabilities to generate a dynamic repair strategy based on an extension to the Beliefs, Desires and Intension (BDI) model referred to as Extensible BDI (EBDI). 1.
