Abstract

As operating systems and other complex software systems become ever more complex the problem of reconfiguring live systems becomes both more important and more difficult. This paper presents a discussion of the key issues for reconfiguring long running software and the use of object versioning and self healing techniques in such systems. We describe adaptive and reconfigurable attributes for a middleware system and report on our experiments with our distributed computing DISCWorld middleware.

Keywords: reconfiguration; long running objects; stable systems.
