HP DCE Administration Tools

 

The Account Manager requires a bit-mapped display; it does not run on

NOTE

 

ASCII terminals. Also, small bit-mapped displays (such as some PC

 

displays), which may cut off portions of dialog boxes, are unsupported.

 

Running the Account Manager

 

 

If you are running the Account Manager locally, you do not need to set

 

the DISPLAY environment variable ($DISPLAY). If you are running the

 

Account Manager from a remote machine, however, use the following

 

command to set the DISPLAY environment variable to the local

 

machine:

 

export DISPLAY=localhostname:0.0

 

If $DISPLAY is not set, the following warning displays:

 

Warning: You are viewing the Account Manager using a remote X

 

display. Passwords and other confidential information will pan

 

over the network in clear text, and may be seen by network pirates.

 

You may wish to exit the Account Manager and run it from a local X

 

display.

 

Start the Account Manager with the following command:

 

/opt/dce/bin/acctmgr

 

If you want to perform privileged operations (such as registry

 

modifications) with the Account Manager, you must run the Account

 

Manager as the DCE cell_admin principal.

 

The Account Manager can also be started as follows from SAM:

 

1. Log in as root.

 

2. Execute sam from a shell prompt.

 

3. Select (double click on) DCE Cell Management.

 

4. Select (double click on) DCE Account Manager.

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.
