Before Installing HP DCE/9000 Version 1.7

Prerequisites

Prerequisites

Hardware and Software Requirements

Any HP system that you want to make a member of a cell must meet certain hardware and software requirements. The system requirements are:

System Type

HP 9000 Series 700 or Series 800.

Operating

 

System

HP-UX 11.0.

Kernel

 

Configuration

See “Series 700 and 800 Kernel Parameter

 

Recommendations” in this chapter for recommended

 

kernel parameter settings.

 

You can check and, if necessary, change these values

 

via SAM (the HP-UX System Administration

 

Manager).

Memory

A minimum 32 Mb of memory is recommended for

 

client-only systems; 64 Mb for server systems.

Swap Space

A minimum 50 Mb of swap space is recommended for

 

client-only systems; at least 100 Mb is recommended

 

for systems running one or more DCE servers. Device

 

swap is strongly recommended over file system swap.

File System

HP DCE/9000 must be installed on a long-name file

 

system. If you have a short-name file system, you must

 

first run convertfs(1m) to convert your file system to

 

long names.

Series 700 and 800 Kernel Parameter Recommendations

Hewlett-Packard has found that the default kernel parameter values for a 11.0 system installed with Runtime bundles are sufficient for running HP DCE 1.7 clients and servers under normal conditions (small cells with hundreds of users) with the following exceptions:

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.
