Configuring HP DCE Cells

Configuring Cells Using dce_config

7.dce_config prompts you to choose the Cell Administrator’s principal name and password. The default principal name for the Cell Administrator is cell_admin:

Enter desired principal name for the Cell

Administrator:(cell_admin)

Enter desired password for the Cell Administrator:

8.dce_config prompts you for the starting point for UNIX user and group IDs that will be generated by the DCE Security Service. This step prevents the DCE Security Service from generating IDs that are already in use by your system. Type < RETURN> to choose the default value, or enter a value of your choice:

S:****** The current highest UNIX ID for persons is N. Enter the starting point to be used for UNIX IDs that are automatically generated by the Secu rity Ser- vice when a principal is added using “rgy_edit “:

( N+100) < RETURN>

S:****** The current highest UNIX ID for groups is N. Enter the starting point to be used for UNIX IDs that are automatically generated by the Security Service when a group is added using “rgy_edit “: ( N+100)

<RETURN>

dce_config then starts up secd and initializes the registry database.

 

S:****** Starting secd…

 

S:****** Checking for active sec_client service...

 

S:****** Starting sec_client service...

 

S:****** Initializing the registry database…

 

This system is now configured as the master Security server. You

 

must now create a CDS server, either on this system or on another

 

system:

 

• If the CDS server for this cell will be on another system, repeat

 

steps 1 and 2 on that system, and continue with step 10 below.

 

• If the CDS server is on the same system as the Security server,

 

continue with step 9 below.

 

Do not configure an additional CDS Server or a replica of a CDS Server

CAUTION

 

on the same system as your Security Server. Such a configuration is

 

illegal and unsupported.

 

9. From the Initial Cell Configuration menu, choose Initial CDS Server:

 

 

selection: 2 (Initial CDS Server)

 

Initial Cell Configuration (on hostname)

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.
