Notes on Cell Administration

Enhanced CDS Browser

•Communication time-out limit

•Cache data time-out limit

You can also set defaults for these options, and can toggle confirmation of non-destructive dialogs.

Manage Replica Locations

You can create a replica of a directory, change the location of a master replica, display information about a replica, and delete a replica from a clearinghouse.

Log in to DCE

You can log in to DCE, either as yourself or as another user, when you need authentication to perform actions. If you lose authentication during an HP CDS Browser session, you can log in to DCE without exiting the browser.

User Interface Enhancements

Icons

When the Browser starts, an icon representing the root directory is the first item to be displayed in the window. Directories, soft links, and object entries all have distinct icons associated with them. The icons are described in the CDS Browser online help in the Online Reference topic under the heading “HP CDS Browser Icons”.

For information about how the icons were created and how they can be modified, see the cdsbrowser (8) man page.

Default Action on Double Clicking

The HP DCE/9000 CDS Browser provides additional “default” actions for double clicking on CDS entries. For example, double clicking on group or profile entries causes the group or profile editor to appear; double clicking on an object, rpc_entry, or soft link entry accesses the Attribute List window. Double clicking on a directory entry expands or collapses the directory.

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.
