Intended for anyone interested in learning about the benefits that this powerful technology has to offer, including managers, system administrators and application programmers, this manual provides an introduction to the OSF Distributed Computing Environment (DCE). OSF's Distributed Computing Environment (DCE) is a blend of technologies from worldwide industry leaders - Hewlett Packard, Digital Equipment Corporation, Siemens and Transarc. It is a fully-integrated set of services that supports the development, use and maintenance of distributed applications, and enables applications to harness effectively the unused power found in many networks. With OSF DCE, users can obtain the maximum value from their installed networks, while providing operating system and network independence, and an architecture designed to incorporate new technologies as they become available. This guide is one of the set of official OSF DCE documentation from the Open Software Foundation.
