About HP DCE/9000 Version 1.7

HP DCE/9000 Core Services Software

HP DCE/9000 Core Services Software

HP DCE/9000 Version 1.7 is based on OSF DCE Version 1.2.1 source code, with bug fixes and value-added functionality. This section describes the contents of this release.

OSF DCE Components Included in This Release

This release includes the following OSF DCE components:

Remote Procedure Call (RPC) Facility, supporting both connection-oriented (TCP/IP) and connectionless (UDP/IP) transport protocols.

User-space Threads, based on Draft 4 of POSIX 1003.4a, Threads Extension for Portable Operating Systems.

Cell Directory Service (CDS), including CDS server replication.

Access to the CDS name space through the X/Open Directory Service (XDS) and X/Open Object Management (XOM) services. The OSF DCE 1.0.3 versions of the XDS, XOM, and dua libraries are a part of libdce, and the necessary XDS and XOM header files are provided.

Security Service, including security server replication and additional security server replication functionality, and the Audit Service.

Distributed Time Service (DTS); this release supports ntp, null, and Spectracom DTS time providers; it also supports global time servers and DCE time zones.

Global Directory Agent (GDA), using the Berkeley Internet Naming Daemon (BIND).

The DCE application library is provided as both a shared library

(libdce.sl) and an archive library (libdce.a). If you use the shared library, a DCE application can share a single copy of the library with other DCE applications that are running on the same host. If you use the archive library, each application binary will contain its own copy of DCE routines that it either directly or indirectly calls.

UX DCE Software specifications

HP UX DCE Software, or Hewlett-Packard UNIX Distributed Computing Environment, represents a significant tool in the realm of distributed system architecture. Designed primarily for enterprise environments, HP UX DCE enhances the reliability, scalability, and manageability of applications over diverse networked systems.

One of the main features of HP UX DCE is its ability to integrate various computing platforms, enabling seamless communication and resource sharing across distributed nodes. This facilitates the creation of complex applications that can operate on a multitude of systems, thus enhancing operational flexibility. DCE employs standardized interfaces, which means applications written for one platform can run on any other platform that supports DCE, promoting cross-platform compatibility.

In terms of technologies, HP UX DCE utilizes Remote Procedure Calls (RPC) as a core feature. This mechanism allows different applications to communicate and invoke procedures on remote systems as if they were local calls. Additionally, DCE includes a robust security model that incorporates Kerberos for authentication, ensuring that communication between nodes remains secure and protected against unauthorized access.

Another significant characteristic of HP UX DCE is its distributed file system, which allows for transparent file access across different machines. The DCE File System (DFS) provides a unified namespace and manages data replication and consistency across distributed storage resources. This reduces the complexity of data management and enhances data availability.

HP UX DCE also supports a variety of programming languages, making it accessible for developers accustomed to different coding environments. This versatility encourages widespread adoption and innovation, as developers can leverage existing skills to create distributed applications.

Furthermore, HP UX DCE is built for high availability, ensuring that critical applications remain responsive even in the face of hardware or network failures. Its inherent component redundancy and fault-tolerant architecture are designed to minimize downtime, which is essential for mission-critical applications in enterprise scenarios.

In conclusion, HP UX DCE Software provides a comprehensive framework for developing, deploying, and managing distributed applications. Its core features such as RPC support, a secure authentication mechanism, a robust file system, and cross-platform compatibility make it a vital resource for organizations aiming to leverage distributed computing effectively. As enterprises evolve, HP UX DCE stands out as an influential solution in the dynamic landscape of distributed environments.
