HP DCE Administration Tools

Tips for New Users

•Log into DCE before starting the Account Manager, or use the Login option from within the Account Manager.

•Establish your preferences in the Options “Preferences” dialog box when you initially start the Account Manager.

If you are administering a very large cell, read “Managing Very Large Cells with Account Manager” below.

•It is recommended that you bring up the Assistant from the File menu when you initially start the Account Manager, and iconize it when not in use.

•Where possible, use batch operations and profiles to automate time-consuming repetitive tasks, such as adding multiple users that have similar characteristics.

Managing Very Large Cells with Account Manager

DCE interfaces can be slow to retrieve lists for very large DCE deployments (For example, if the DCE registry is managing many thousands of users). The performance of the Account Manager will be affected in this case. To aid the Account Manager’s performance for very large deployments, take the following steps:

1.In the Options/Preferences dialog, enable the option to “Display -User/Group/Org/Attribute_Type List as Text instead of Icons.”

The Account Manager requires major resources to map very large lists into iconic display, and this option is needed to bypass that step.

2.In the Options/Preferences dialog, disable the option to “Display

-User/Group/Org/Attribute_Type List at Start Up”. This step should be done if any of the following are true:

•You know the names of the objects you want to manage.

•You will manage only a subset of objects (for example, users in a certain group).

•You will ask the Account Manager to read in the list of objects to manage from a file (see #3 below).

In this step, the first time that you navigate the Account Manager to an object management screen (for example, User Management), the list will be empty.

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.
