HP DCE Measurement Service

Accessing DMS Data

For a definition of any metric, select the metric name by clicking on it using the right mouse button; a pop-up help window appears containing the definition of the metric.

DCE Process List Window

The DCE Process List Window displays a list of all processes running on your system that are DCE servers. For each process displayed, several metrics are available by default. You can customize the metrics displayed using the “Choose Metrics” command under the “Configure” pull-down menu. Each process shown can be selected or filtered.

For a selected process, you can obtain more detailed information. You generate this information by selecting the “Reports” pull down in this window and selecting “Process DCE Interface” or “Process Activity”. You can also select “Process Activity” by double-clicking on a process.

DCE Process Activity Window

The DCE Process Activity Window displays very detailed process information for a selected DCE process. All metrics available for the selected DCE process are displayed in a single window.

 

DCE Interface Window

 

Interface and operation names are not available in HP GlancePlus until

NOTE

 

after the first call to an interface. After the first call to an interface, the

 

interface name and all of its operation names become available, but

 

GlancePlus won’t pick up the interface and operation names unless you

 

close the window and then re-open it. Interfaces, such as rpc_mgmt

 

(which is exported by every DCE server and client), whose UUIDs and

 

version numbers match interfaces that have previously been registered

 

and named are available even before being called within a given process.

 

The DCE Interface Window displays a list of the interfaces associated

 

 

with a DCE process. For each process displayed, several metrics are

 

available by default. You can customize the metrics displayed using the

 

“Choose Metrics” command under the “Configure” pull-down 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.
