Introduction to Remote Server Call
(RSC/MP)
This section provides an overview of Remote Server Call (RSC/MP), including its
features, components, and operation.
Overview of Features
RSC/MP allows workstations to access Pathway servers and other Guardian
processes on a NonStop system. With RSC/MP, you can implement powerful
client/server applications—the workstation is the client; the NonStop system, with its
Pathway/TS online transaction processing (OLTP) software, is the server.
RSC/MP offers these features:
•
Takes advantage of the power of the workstation with its extensive processing
capabilities and easy-to-use graphical user interfaces (GUIs).
•
Takes advantage of the power of a NonStop system, including Pathway/TS and
existing Pathway servers, NonStop SQL or Enscribe databases, and the HP
NonStop Transaction Management Facility (TMF).
•
Provides an application program interface (API) that is independent of the
workstation platform and the communications protocol.
•
Supports unsolicited messages sent from any process on a NonStop system to a
workstation.
•
Supports asynchronous, NetBIOS, TCP/IP, and IPX/SPX data communications
protocols. In all cases, the data communications protocol is transparent to the
application.
•
Takes advantage of powerful application development tools on the workstation.
•
Provides security for the NonStop system, including verification of workstation
access to processes on the NonStop system.
The Remote Server Call (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
