Proactive self-healing system for application maintenance in ubiquitous computing environment

With evolving modern IT technology, one desirable characteristic of distributed of applications is self-healing, or the ability to reconfigure themselves "on the fly" to circumvent failure. Thus, the goal is to avoid catastrophic failure through prompt execution of remedial actions. This paper proposes a self-healing system that monitors, diagnoses and heals its own internal problems using self-awareness as contextual information. The proposed system consists of multi agents that analyze the log context, error events and resource status in order to perform self-diagnosis and self-healing. For rapid and efficient self-healing, for developing the proposed system, we use a 6-step process: monitoring, filtering, translation, diagnosis, decision and feedback. Our experiments conducted with a prototype system confirm the effectiveness of the proposed system.
