Ensuring Dynamic Reconfiguration Consistency

By N. De Palma, De Palma Laumay and L. Bellissard


The evolution of distributed applications to reflect structural changes or to adapt to specific conditions of the run-time environment is a difficult issue especially if continuous service is required from end-users. This latter constraint implies to perform changes with minimal penalty on the service provisioning. The set of tools and services that allow such a goal to be achieved is usually designated as dynamic reconfiguration capabilities. A major issue related to dynamic reconfiguration is to ensure applications consistency after a reconfiguration. Classical transactional models provide a way to identify application calculations and to ensure consistency of these calculations despite faults. In a first step, we propose an extended transaction model to ensure such a consistency when a reconfiguration occurs. We argue that ensuring consistency can be done easily by using an extended transaction model with a strong isolation property. Then we discuss possible solutions for non transactional applications
