Generating synchronization engines between running systems and their model-based views

The key point to leverage model-based techniques on runtime system management is to ensure the correct synchronization between the running system and its model-based view. In this paper, we present a generative approach, and the supporting tool, to make systematic the development of synchronization engines between running systems and models. We require developers to specify “what kinds of elements to manage” as a MOF meta-model and “how to manipulate those elements using the system's management API” as a so-called access model. From these two specifications, our SM@RT tool automatically generates the synchronization engine to reflect the running system as a MOF-compliant model. We have applied this approach on several practical systems, including the JOnAS JEE server.
