Accessing DMS Data

After you start GlancePlus with the gpm command, you can select screens that display DCE metrics.

Five HP GlancePlus screens display DCE metrics:

•DCE Global Activities Window — Provides global status of DCE services on your system.

•DCE Process List Window — Provides a list of all DCE processes on your system running with euid equal to root.

•DCE Process Activity Window — Provides very detailed information about a DCE process selected in the Process List window.

•DCE Interface Window — Provides detailed information about the DCE interfaces for a DCE process selected in the DCE Process List Window.

•DCE Operation Window — Provides detailed information about the DCE operations in progress within a selected DCE Interface. You may choose which metrics are displayed in this window.

The following sections provide a brief description of the information provided in the windows. For more information, see the online help provided with DMS.

The DCE Global Activities window provides overview statistics for an RPC server; the remaining windows provide detail information about various DCE activities.

DCE Global Activity Window

The DCE Global Activity window displays detailed summary information about all of the DCE activities occurring on your system. The window includes two areas of focus:

•DCE activities of general interest — These metrics provide a global view of the DCE services running on your system.

•DCE summary information — These metrics provide a high-level view of total DCE activity on your system, including all DCE server requests and machine resource utilization for the DCE service.

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.
