Configuring HP DCE Cells

Configuring Cells Using dce_config

3.dce_config prompts for a name for the security replica. Enter whatever name you wish:

Enter the Security Replica name (without subsys/dce/sec): sec_rep_node

S:****** Modifying acls on /.:/sec/replist…

S:****** Modifying acls on /.:/subsys/dce/sec…

S:****** Modifying acls on /.:/sec…

S:****** Modifying acls on /.: …

S:****** Modifying acls on /.:/cell-profile…

4.dce_config prompts for a key seed; enter any sequence of characters:

Enter keyseed for initial database master key:

 

Configuring the DCE Audit Service

 

At HP DCE 1.4.2, the dce_config utility automatically enabled audit

 

filtering by setting DCEAUDITFILTERON before starting any DCE

 

servers; in addition, when you invoke the “Auditing” command from the

 

dce_config “Additional Server Configuration” menu, dce_config

 

specifies a set of default audit filters before starting auditd, the audit

 

daemon. You can use the dcecp audfilter command to delete or modify

 

these default filters, or to create new filters. See the -audfilter (1M) man

 

page for more information on how to do this.

 

If you want to enable auditing, you must explicitly start the audit

NOTE

 

daemon by selecting 9 (Auditing) from the dce_config “Additional

 

Server Configuration” menu. Not starting the audit daemon is

 

functionally equivalent to setting DCEAUDITOFF, effectively disabling

 

auditing.

 

If you want to disable auditing completely, set the DCEAUDITOFF

 

 

environment variable to 1 on each node where you intend to run a DCE

 

server before starting the cell’s servers.

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.
