name. It is appended to the host name to get the fully qualified name in this format: host_name.domain_name (for example: if DOMAIN_NAME=foo.bar.com and host name=abc, the fully qualified host name will be abc.foo.bar.com).

EXIT_ON_ERROR: Set to y to exit from dce_config if a fatal error is encountered. Default is n. This can prevent a here-document from getting out-of-sync with dce_config.

GID_GAP: Increment above highest currently-used GID at which the Registry Service will start assigning automatically-generated GIDs. Default is 100.

HOST_NAME_IP: IP address of node on which dce_config is running.

HPDCE_DEBUG: Set to 1 starts daemons in the foreground.

KEYSEED: Key seed for initial database master key.

LAN_NAME: Internal name of the LAN (in the LAN profile) when using multiple LANs. Use when configuring a CDS server.

LOW_GID: Value at which the Registry Service will start assigning automatically-generate d GIDs. Default is the value of the highest currently used GID plus $GID_GAP. If $LOW_GID is less than or equal to the highest currently used GID, a warning is issued, and user is prompted to enter a new value (which can be the value of $LOW_GID).

LOW_UID: Value at which the Registry Service will start assigning automatically-generated UIDs. Default is the value of the highest currently used UID plus $UID_GAP. If $LOW_UID is less than or equal to the highest currently used UID, a warning is issued, and user is prompted to enter a new value (which can be the value of $LOW_UID).

MULTIPLE_LAN: Set to y to configure this node with multiple LAN capability. Use when configuring a CDS server. Default is n.

NTP_HOST: Host name on which the NTP server is running.

TP_DEV: Name of device to which Spectracom time source is

attached. Example: /dev/tty00.

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.
