HP NCS 1.5.1 for the HP 3000 Technical Data
The NCS 1.5.1 Product is the Network Computing System Remote Procedure
Call version 1.5.1 for our HP 3000 MPE/iX systems. NCS 1.5.1 provides
capabilities for transparently making network resources available to
users and applications by allowing applications written to NCS 1.5.1 to
be distributed.
[Figure 1 (HP NCS 1.5.1 for the HP 3000) Caption: none]
NCS 1.5.1 is the basis for the NCS component of DCE, OSF's Distributed
Computing Environment. By providing NCS 1.5.1 for MPE/iX, a migration
path is provided for MPE applications moving to DCE.
NCS 1.5.1 is a Remote Procedure Call. It allows remote execution of
client procedures on servers throughout the network. NCS RPC makes it
possible to develop and run application procedures remotely allowing
them to use network resources without causing network traffic, improving
performance for enterprise-wide data access and allowing network
resource scalability for future growth.
NCS provides the base foundation for OSF's DCE, the enabling technology
for enterprise-wide heterogenous distributed computing in the future.
NCS 1.5.1 on MPE/iX provides a strong foundation of growth for HP 3000
customers moving to DCE environments by enabling multivendor application
integration. NCS also provides the HP 3000 with improved capabilities
for building distributed applications and integrating existing
applications, providing a core foundation for distributed OLTP and data
access applications in the future.
Benefits of NCS:
o Optimum Use of Network Resources: By using NCS RPC, parts of
applications can be split to run on server systems closer to the data.
This allows better use of the network, faster data access, and better
use of processing power.
o Multivendor Application Integration: NCS 1.5.1 is adopted by the
major vendors and is the basis for the DCE Remote Procedure Call. By
developing applications using the NCS 1.5.1 RPC, the applications have
an easy migration path to the DCE environment in the future. NCS 1.5.1
will provide interoperability with the next generation of DCE
environments.
o Ease of Client/Server Application Development: NCS 1.5.1 RPC enables
applications to be written in a client-server module. Client
applications can run specific procedures on servers to take advantage
of server functionality. For example, an inventory application running
on a client can have a data update procedure run directly on the
appropriate database server and then automatically return results to
the client upon procedure completion.
NCS Product Structure
NCS 1.5.1 for MPE/iX consists of two components:
The Network Computing Kernel {NCK} is required to execute NCS
applications, and the Network Interface Definition Language {NIDL} is
required to actually develop the NCS 1.5.1 applications.
15
The NCK Kernel on MPE/iX provides runtime support for distributed NCS
applications and has been tested between NCK implementations on the
HP/UX Series 9000/3xx and 8xx platforms. It consists of a set of
intrinsics that are accessed by applications at runtime. This Kernel
offers applications the ability to execute across networks and
facilitates the communication to manage distributed processing.
NIDL on MPE/iX is a tool for developing distributed applications. It
provides the NCK Kernel the environment for building those applications
by taking input and generating client and server stub programs.
NCS 1.5.1 consists of both above components.
Product Requirements:
NCS 1.5.1 will run on MPE/iX version 4.0 or later. It requires the
following network and system software to run:
o MPE/iX C compiler and C runtime library
o NS 3000/iX LAN LINK and Transport
o NS 3000/iX Network Services
Ordering Instructions:
NCS 1.5.1 for MPE/iX is being shipped as a limited distribution product.
For information on ordering NCS 1.5.1 for MPE/iX, contact the network
sales center at 447-4444.
