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 NetBIOS and TCP/IP 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 ve rification 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
