Configuring HP DCE Cells

Configuring Cells Using dce_config

REMOVE_PREV_INSTALL: Set to y to remove all remnants of previous DCE installations for all components before installing a security server. Use only in installing the security server software. Default is n.

REMOVE_PREV_CONFIG: Set to y to remove all remnants of previous DCE configurations for all components before configuring a client or an initial CDS server. Default is n.

REP_CLEARINGHOUSE: Name for new clearinghouse.

SEC_SERVER: Name of the security server for this cell.

SEC_SERVER_IP: IP address for $SEC_SERVER.

SYNC_CLOCKS: Set to y to synchronize client clock with that of the security server; n otherwise. If not set, and clocks are out of sync by more than $TOLERANCE_SEC, user is prompted for whether to synchronize. This variable is irrelevant if CHECK_TIME is set to n.

TOLERANCE_SEC: Number of seconds client node system clock is allowed to differ from security server system clock before warning that clocks are not in sync and allowing input to synchronize. Default is 120 seconds. Note: Security and Cell Directory services require less than a 5 minute difference between any two nodes in the cell.

UID_GAP: Increment above highest currently-used UID at which the Registry Service will start assigning automatically-generated UIDs. Default is 100.

UNCONFIG_HOST_PRESET: Host name of node to be unconfigured.

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.
