RSC/MP Installation and Configuration Guide

1 Introduction
What is RSC/MP?
Remote Server Call/MP (RSC/MP) software lets yo u use personal computers (PCs)
and workstations to communicate with Pathway servers and other NonStop processes
on a NonStop system. The NonStop system can act as the host to one or many client
workstations.
RSC/MP permits workstations to invoke NonStop Transaction Services/MP (TS/MP)
servers on NonStop servers. By providing a client-serve r environment, RSC/MP can
improve the performance of NonStop TS/MP applications while maintaining the ability
to handle high-transaction volumes.
RSC/MP provides the link between NonStop servers and client workstations over
existing communication networks. Clients may communicate with a NonStop server
over a LAN using TCP/IP or NetBIOS.
The RSC/MP application program interface (API) lets you develop custom user
interfaces to the NonStop system. Application programs running on the workstation
use RSC/MP‘s API to send and receive messages from NonStop processes. These
RSC/MP application programs can be written in a variety of programming languages,
including C, Visual Basic, and PowerBuilder. For an extensive description of the
RSC/MP API, see the Remote Server Call (RSC/MP) Programming Manual.
The RSC/MP Environment
RSC/MP is made up of components on the workstation (the client) and the NonStop
system (the server).
Figure 1-1 illustrates the RSC/MP components and shows how RSC/MP provides
access to Pathway servers and other Guardian processes. In this diagram, ovals
represent processes. The double arrow between the workstation and host represents
the communication line or network that connects the two. Other arrows show the
directions of data movement among the components. Components shown in gray are
supplied by RSC/MP. The other components are either written by the user, or are
system components.
