Self-adaptive multithreaded applications

Abstract

Shorter product cycles, the requirement for immediate reaction to cyber-attacks and the need for the adaptation to changing environmental conditions demand software reconfigurations to be performed at runtime, in order to reduce downtime. Especially long running applications, which have to provide continuous service should not be restarted for maintenance. They must be updated dynamically.We have developed a reconfiguration strategy allowing to identify valid reconfiguration points even in multithreaded environments, enabling dynamic application updates. The usage of dynamic aspect weaving enables us to transparently create self-adaptive applications without additional compilation steps or programming constraints in the software development process.We demonstrate how our approach can be applied to a real-world retail application of a large logistics company. We will describe the implementation of the reconfiguration aspect and our dynamic aspect weaving tool Rapier LOOM.NET.

“…A C #-based COP framework known as ContextCS [12] was proposed in previous research. This framework uses the Observer Aspect [14] to manage the context according to priority, and a controller to manage the layer activation order. This method implements the layer activation method based on priority to a certain extent.…”
