NAME
sna - SNAplus2: SNA and APPN communications for HP-UX
DESCRIPTION
The following descriptions are provided as a very brief overview of selected SNA (Systems Network Archi-
tecture) utilities that are available as optional software for use with the HP-UX operating system. For
more information refer to system documentation provided with the software. For purchasing information,
contact your nearest HP Sales and Support Office.
SNAplus2 is a communications software product which permits users of a HP-UX computer to communicate
with remote computers using IBM SNA protocols. It implements a LEN Node, APPN End Node, or APPN
Network Node according to its configuration; this includes SNA node type 2.0 and 2.1 support for communi-
cating with host and peer computers.
SNAplus2 may be used on a single HP-UX computer, or as a Client-Server system with users and programs
distributed across a LAN (communicating using TCP/IP). The core communications components run on
HP-UX servers; client computers may be running either HP-UX or Windows.
SNAplus2 supports communications using the following connectivity types:
SDLC
QLLC
TR
FDDI
ETH
It allows the following types of communications tasks:
3270 and 3179G emulation
Your terminal acts as a 3270 terminal, or as a 3179G graphics display terminal, allowing you to access
programs on host computers.
LU 6.2 Communications (APPC and CPI-C)
Advanced Program-to-Program Communications (APPC) and Common Programming Interface for
Communications (CPI-C) both allow communication between transaction programs (TPs) on different
systems across the SNA network.
Conventional LU API (LUA)
LUA allows applicationprograms to communicate with existing IBM host applicationsusing any of the
LU types 0, 1, 2, or 3.
Remote Job Entry (RJE)
RJE allows SNAplus2 users to submit jobs to a host Job Entry Subsystem for processing.
In addition to APPC, CPI-C, and LUA, SNAplus2 also provides the following APIs for use by application
programs:
High-Level Language Application Programming Interface (HLLAPI)
HLLAPI interacts with a 3270 emulation session by performing the tasks that would normally be per-
formed by a 3270 user, such as searching for data on the screen and entering keystrokes. It can be
used to automate standard 3270 tasks.
Common Service Verbs (CSV)
The CSV API provides utility functions such as character translation, trace control, and message log-
ging.
Management Services (MS)
The MS API allows a SNAplus2 application to communicate with other Management Services pro-
ducts or applications across the network, by sending and receiving management data either in NMVT
format or in MDS_MU format.
Node Operator Facility (NOF)
The NOF API allows an application to configure and manage SNAplus2 resources; the application can
define, modify, or delete resources, start or stop resources, or obtain information on the configuration
or current status of resources.
SNAplus2 also provides the following features:
TN Server
SNAplus2 allows TN3270 programs (3270 emulation programs that communicate over TCP/IP)
