DCE (Distributed Computing Environment)
VSI DCE provides a set of the distributed computing functionality specified for The Open Group TM 's (OSF R Distributed Computing Environment (DCE) as well as tools for application developers.
Distributed computing services, as implemented in the VSI Distributed Computing Environment (DCE), provide an important enabling software technology for the development of distributed applications. DCE makes the underlying network architecture transparent to application developers. It consists of a software layer between the operating system/net work interface and the distributed application program. It provides a variety of common services needed for development of distributed applications, such as name and time services, and a standard remote procedure call interface. VSI DCE for OpenVMS VAX and OpenVMS Alpha provides a means for application developers to design, develop, and deploy distributed applications. This release supports the OpenVMS VAX, Alpha, and I64 operating systems. DCE Cell Directory Service (CDS) provides location-independent naming for resources.
