Configuring Cells with DCM

Overview of DCM Functionality

DCM enables you to perform the following cell configuration tasks:

•In a configured and running cell, if the primary DCE services (Initial CDS and Master Security) are running on HP systems (as opposed to other vendors’ systems), you can configure additional HP DCE 1.2, 1.2.1, 1.3.1, 1.4, 1.4.1, 1.4.2, 1.5, 1.6, or 1.7 clients into the cell from any HP DCE 1.7 cell member system.

•Create a cell of one or more systems. DCM provides a “template” mode that simplifies cell creation.

•User authentication of cell configuration operations.

•Add and remove client systems (systems running DCE client software only) to an existing cell from any system in the cell.

•Add replicated security servers to an existing cell.

•Add additional CDS servers to an existing cell. You can add new systems to the cell as CDS servers, or reconfigure existing cell members as CDS servers.

•Add or modify local or global DTS servers or DTS clients in the cell and modify ntp, spectracom, or null DTS time providers in the cell.

•Add or remove GDA servers on existing cell nodes.

•Stop all DCE daemons on all cell members or selected cell members.

•Restart all DCE daemons on all cell members or selected cell members.

•Destroy (unconfigure) an existing cell.

At the heart of DCM is an object list screen that displays a list of all cell members and their attributes. The attributes include a cell member’s name, and the DCE services (if any) configured on the member. You perform tasks on selected cell members by selecting (highlighting) the desired members in the list and then selecting the appropriate actions from an Actions menu.

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.
