Architectural reconfiguration using coordinated atomic actions

Abstract

The provision of services despite the presence of faults is known as fault tolerance. One of its associated activities is fault handling, which aims to prevent the reactivation of already located faults. System reconfiguration, one of the steps of fault handling, is a complex cooperative activity involving several participants, thus should be designed in a structured fashion. This position paper describes how coordinated atomic actions (CAactions) and exception handling can be applied to the architectural reconfiguration of systems.
