About HP DCE/9000 Version 1.7

HP DCE/9000 Core Services Software

The DCE cell diagnostic tool dceping.

An enhanced version of the OSF CDS browser (cdsbrowser), which has been ported to Release 6 of the X11 Windows system and the Common Desktop Environment (CDE). The browser is accessible through SAM. See the CDS Browser online help (accessible via the CDS Browser Help menu) for details.

Two sets of tools for developing DCE applications are available as separately priced options to HP DCE/9000. For DCE application development in C, HP DCE/9000 Application Development Tools includes a modified IDL compiler (I2DL), tracing and logging facility, error reporting facility, and sample applications. For DCE application development in C++, HP DCE/9000 Object-Oriented DCE (HP OODCE) includes an IDL++ compiler, tracing and logging facility, C++ class library, sample applications, include files, and modified header files for C++ application development.

cdsclerk (new at HP DCE 1.5) no longer runs as separate processes. cdsclerk functionality has been merged into the cdsadv process. cdsadv, therefore, is now the only HP DCE CDS client process.

HP’s dced (new at HP DCE 1.5) supports the new -roption. This option starts dced in remote-update mode, which allows DCE cell administration tasks to be performed by an administrator on a remote machine. In order to help prevent attacks, the dced default behavior is to disallow any remote administration.

HP has enhanced the dcecp registry connect command with two new options that support intercell login:

-acctvalidMarks the local cell account as a valid account. A valid local cell account allows users from the foreign cell to login to nodes in the local cell. The default is invalid.

-facctvalidMarks the foreign cell account as a valid account. A valid foreign cell account allows users from the local cell to login to nodes in the foreign cell. The default is invalid.

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.
