Open framework for the dynamic reconfiguration of component-based software

Permanent and uninterrupted fuctioning can be sometimes a requirement for some kinds of software systems. This is especially true in the case of complex and distributed systems where stopping and restarting the system constitute a tedious and costly task also when the system must be highly available or when its execution environment changes frequently. The development complexity and cost constitute an important problem in front of the creation of dynamic software systems. We present in this paper a reusable framework that helps to make software systems dynamically reconfigurable. Our solution has been implemented for Java systems respecting some lexical conventions and allows to automatically enhance an ordinary system by the dynamic reconfiguration capabilities.
