Description
PRODUCT NAME: HP Distributed Computing Environment SPD 43.05.11
(DCE) Version 3.2 for OpenVMS Systems
DESCRIPTION
The HP Distributed Computing Environment for OpenVMS product family 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. With DCE, The Open Group has
established a standard set of services and interfaces that facilitate the creation, use, and maintenance of
client/server applications. DCE for OpenVMS serves as the basis for an open computing environment
where networks of multivendor systems appear as a single system to the user. Because DCE makes the
underlying networks and operating systems transparent, application developers can easily build portable,
interoperable client/server applications. Users can locate and share information safely and easily across the
entire enterprise. DCE for OpenVMS supplies system managers with a set of tools to consistently manage
the entire distributed computing environment, while also assuring the integrity of the enterprise. The DCE
for OpenVMS product family supports both the OpenVMS Alpha and I64 Operating Systems.
The functionality provided in the DCE for OpenVMS product family includes:
• DCE Remote Procedure Call (RPC): Used to create and run client/server applications, the
RPC allows direct calls to remote systems as if they were local procedure calls.
• DCE Distributed Time Service (DTS): Synchronizes time on individual nodes in a distributed
network environment.
• DCE Security Service: Provides secure communications and access via authorization and
authentication services.
• DCE Cell Directory Service (CDS): Provides location-independent naming for resources.
• Global Directory Agent (GDA): The GDA provides a means of linking multiple CDS
namespaces via either X.500, LDAP, or the Internet Domain[R] Name Server (BIND).
• GDA over LDAP support: Enables the use of LDAP by the Global Directory Agent in looking
up information on foreign cells.
• NSI over LDAP support: Enables the use of LDAP by the Name Service Interface Daemon in
looking up information on behalf of Microsoft RPC applications.
• DCE code set registry: Provides a mechanism for uniquely identifying code sets and the
character sets they encode across multiple heterogeneous operating systems in an
internationalized DCE cell.
• The Interface Definition Language (IDL) compiler: IDL is the language used to define remote
procedure calls.
• Tools and utilities that help manage the DCE environment.
