About HP DCE/9000 Version 1.7

Features Planned for a Future Release

Features Planned for a Future Release

This section describes OSF DCE and HP DCE features that will be supported in future releases of HP DCE.

64-bit libraries to support DCE 64-bit application development

Kernel-threaded (POSIX 1003.1c) DCE

LDAP NSI version for 10.20 and 11.0

Improved scalibility, robustness, and availability

Improved administration and configuration

Future Support for POSIX 1003.1c Threads

CMA applications are likely to migrate from Draft 4 of the POSIX threads standard to the final, ratified 1003.1c standard for kernel threads. This migration will result in source incompatibility, and it is recommended that application developers plan now for this transition. HP plans to preserve binary compatibility. However, developers can prepare for this change as follows:

1.Isolate new threads API usage to macros or wrapper APIs.

2.Minimize the use of signals, and use only POSIX semantics when programming with signals.

For example, we recommed that thjreaded applications use only the functions sigaction(), sigprocmask(), and sigwait().

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.
