Announcing DCE/3000 

by Joe-Sue Wang 
General Systems Division 

Product Description 

The Distributed Computer Environment (DCE) technology was originally
designed by Open Software Foundation (OSF). The services that are
provided in DCE are acknowledged by the industry as the most complete and
comprehensive framework for data and applications to be distributed
transparently across the networks and systems.

DCE/3000 has been an orderable product since May 1, 1995.  The new
version of DCE/3000 (version A.01.12), is available beginning with
MPE/iX-Express 3 based on General Release 5.0.  DCE/3000 version A.01.12
is still based on the OSF DCE 1.0.2 implementation.  However, the DCE
library is provided as both an archive (libdce.a) and an executable
library (DCEXL.HPDCE.SYS).

The addition of DCE to the HP 3000 platform enables the DCE-based
applications to run on the MPE/iX operating environment.

Supported Components.   

DCE/3000 provides all the core services that are required for a DCE cell
to function correctly.  A cell is the basic unit of operation and
administration in DCE. The core services include:

   *   Remote Procedure Calls (RPC). They support the development of
       distributed applications by making requests to remotely networked
       machines as if they were local.  RPCs also implement network
       protocols used by clients and servers to communicate with each
       other.

   *   Cell Directory Service (CDS). It manages a database for the
       resources in a group of machines called a DCE cell.  The database
       consists of the names of resources and associated attributes.

   *   Distributed Time Service (DTS). It provides synchronized time for
       the computers in the distributed computing environment.

   *   DCE Security.  It provides secure communications through use of
       services such as authentication which guarantees the identity of
       users, and authorization which keeps track of what privileges the
       user may be granted.
