Configuring HP DCE Cells

 

 

Configuring Cells with DCM

 

By using the List menu, you can switch to a template mode that allows

 

you to create prototype DCE cell configurations that can (and must) be

 

tested for validity before actually being created.

 

Important Security Warning

 

DCM uses standard UNIX remote login utilities to perform remote

CAUTION

 

administration. This causes the cell administrator’s password to be sent

 

over the network whenever you perform a task on a remote system. If

 

someone is very closely monitoring the network traffic, they could obtain

 

the password and the security of the cell’s DCE services will be

 

compromised. Note, however, that using DCM is no more or less secure

 

than using standard UNIX remote login utilities directly. (Secure

 

Internet Services (SIS) do not provide better security for the purpose of

 

remote DCE cell administration.)

 

Requirements for Running DCM

 

 

If you choose to configure your cell with DCM, you should verify that the

 

systems in your cell meet the following requirements:

 

All systems from which you want to perform cell configuration tasks

 

 

must have SAM installed.

 

All systems must have the host name of each node (the

 

 

administrative node and cell members) in their .rhosts and

 

 

/etc/hosts.equiv files. The .rhosts file must be located in the root

 

 

user’s home directory, usually the / directory. For more information

 

 

about .rhosts files, see Using ARPA Services (B1014-90006), and the

 

 

remsh (1) and hosts.equiv (4) man pages.

 

All systems that you want to administer via DCM must be running

 

 

HP DCE/9000 Version 1.2 , 1.2.1, 1.3.1, 1.4, 1.4.1, 1.4.2, 1.5, 1.6, or

 

 

1.7. DCM does not configure and may not “discover” all aspects of

 

 

other vendors’ system configuration.

 

Running DCM

 

To run DCM:

 

1.

Log in as root.

 

2.

Execute sam from a shell prompt.

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.
