2 Introduction to SNAplus2

This chapter provides an overview of SNAplus2 features and shows some of the basic conﬁgurations in which

SNAplus2 can be used. It describes the major components of SNAplus2 and the SNA resources that are con

for and used by SNAplus2, and provides an overview of SNAplus2 administration responsibilities and tools.

2.1 What Is SNAplus2?

SNAplus2 is a software product that enables HP-UX computers to participate in an SNA network that includes

mainframes, PCs, and other computers. With SNAplus2, you can access data and programs that reside on other

computer systems, thereby increasing your computing power.

SNAplus2 includes the following facilities:

SNA communication facilities

SNAplus2 nodes can operate within an SNA subarea network, within an APPN network, or within both at

the same time. For more information about SNA support supplied by SNAplus2, see Section 2.3.1, Node

Components.

Passthrough services

SNAplus2 includes services that support communication between a host and computers on a LAN, making it

possible to reduce the number of communication links to the host, simplify conﬁguration of SNA nodes, and

provide host access for computers that have no direct link to a host. For more information about passthrough

services, see Section 2.3.1, Node Components.

User applications

SNAplus2 supports the following user applications:

• 3270 emulation

• 5250 emulation

• Remote job entry (RJE)

• APPC Application Suite

For more information about user applications, see Section 2.3.2, User Applications.

Application programming interfaces

SNAplus2 includes application programming interfaces (APIs) that you can use to write user application

programs or SNAplus2 administration programs. For more information about SNAplus2 APIs, see Section

2.3.3, Application Programming Interfaces.

LAN facilities

Within a TCP/IP local area network (LAN), SNAplus2 supports communication between servers (SNA nodes)

and clients (HP-UX or Windows computers).For more information about client/server facilities on a LAN,

see Section 2.3.4, Client/Server Support.

Windows clients

WINDOWS

SNAplus2 provides support for Windows clients (running Microsoft Windows 2000, Windows XP, Windows

Server 2003, Windows 3.11, or Windows for Workgroups), enabling them to access SNA resources through

SNAplus2 servers. The APIs provided for Windows clients support 3270 and 5250 emulation and enable the
