Before Installing HP DCE/9000 Version 1.7

Prerequisites

maxfiles must be increased to a minimum of 256 for all systems.

The default value for maxdsize is sufficient except in cases where you have many tens of thousands of users. At this point you should monitor the process size of your secd and cdsd. If the process size approaches the maxdsize value, maxdsize should be increased.

Kernel parameter tuning is highly application dependent. It is expected that you might need to modify your kernel parameters based upon your specific applications needs.

Distribution Media

The HP DCE/9000 Version 1.7 software is shipped on CD-ROM only.

The HP DCE/9000 Version 1.7 International Client software is shipped bundled with HP-UX 11.0. The domestic version of the client is available on the HP-UX 11.0 AR and is codeword-protected. To obtain a codeword, follow the instructions on the codeword certificate that was shipped with the CD-ROM disc.

The HP DCE/9000 Version 1.7 Server software is available on the HP-UX 11.0 AR CD-ROM and is also codeword-protected.

See the Managing HP-UX Software With SD-UX for more information on distribution media.

Network Distribution Area

The first part of the installation procedure involves loading software from distribution media to a network distribution area or depot. The drive where the distribution media is loaded must be connected to a system that has sufficient disk space available. To calculate the disk space required, refer to Tables 3-1 and 3-2 at the end of this chapter.

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.
