Configuring HP DCE Cells

Configuring Cells Using dce_config

Initial Cell Configuration

As of HP DCE 1.6, dce_config sets the DCEAUDITFILTERON environment variable to enable audit filtering, which limits the range of audit event types logged. It you want to disable or change the default settings provided by dce_config, you must do so before starting any server that provides data to the Audit Service. See “Configuring the DCE Audit Service” in this chapter and “The DCE Audit Service” in Chapter 1.

HP DCE 1.6 and 1.7 do not support DFS. Therefore, you can ignore references to DFS that still appear in configuration menus. If you choose DFS Client from the DCE Configuration Menu, for example, a message displays that the bits are not loaded.

When creating an HP DCE cell, servers must be configured before clients. First configure a Security server, then a CDS server, a Time server, and finally a single Time provider. Then you may configure clients.

When planning a DCE cell, note that you must configure a CDS client on any Security server system that is not running a CDS server. You must also configure a Time client on any system that is not running a Time server. Be sure to configure these clients only after you have configured all servers.

Client configuration is discussed in “Configuring Client Systems: Security, CDS, and DTS” later in 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.
