One of the four major processes of an autonomic computing system is to free people from
discovering, recovering, and failures, this process is called self-healing. Systems designed to
be self-healing are able to heal themselves at runtime in response to changing environmental
or operational circumstances. Thus, the goal is to avoid catastrophic failure through prompt
execution of remedial actions. This paper proposes a self-healing mechanism that monitors,
diagnoses and heals its own internal problems using self-awareness as contextual
information. The self-management system that encapsulates the self-healing mechanism
related to reliability improvement addresses: (1) Monitoring layer, (2) Diagnosis & Decision
Layer, and (3) Adaptation Layer, in order to perform self-diagnosis and self-healing. To
confirm the effectiveness of self-healing mechanism, practical experiments are conducted
with a prototype system.
