Dynamic reconfiguration in an object-based programming language with distributed shared data

An approach to dynamic reconfiguration in online distributed applications based on a data sharing model is presented. The data sharing model consists of facets, objects, and processes, with facets as the unit of sharing. The primary contribution of this work is the addition of important special cases of dynamic reconfiguration, without resorting to general dynamic allocation. A metaphor consistent with PROFIT's data sharing model for expressing dynamic reconfiguration facilities within the programming language is proposed.
