Installing HP DCE 1.7

 

Loading HP DCE Software in a Network Source Area

 

If you are performing this install as a step in migrating a server system

NOTE

 

from a previous version of HP DCE, create a single depot containing the

 

HP DCE 1.7 software and the DCE client software that is bundled with

 

HP-UX 11.0. See Chapter 2 for information on migrating from a previous

 

HP DCE version. The target depot path is the pathname to the directory

 

where you want the HP DCE software to be loaded. As a general rule,

 

you should accept the HP-UX default /var/spool/sw.

 

5. Specify the source hostname and source depot path in the “Specify

 

 

Source” popup window.

 

The source hostname is the name of the machine on which the media

 

device is mounted; the source depot path is the device pathname.

 

When you have specified these fields, a list of the products and

 

bundles available in that source depot (i.e., on the media) is displayed

 

in the “Software Selection” window.

 

6. Select the DCE products to load.

 

After you select (double-click on) the DCE bundle, a list of the DCE

 

products is displayed. Mark all the listed DCE products for loading.

 

7. Load the software into the depot.

 

Select “Copy” from the Actions menu.

 

If your software media was shipped with a codeword certificate, follow

 

the instructions on the certificate to obtain a codeword before you

 

load the software into the depot. Before you load software that

 

requires a codeword, you must enter a valid codeword and hardware

 

ID. If a codeword is not required for your software, answer “no” to the

 

question “Do you want to enter your authorized codeword to access

 

the protected software?”.

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.
