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 Architecture) 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 communicating 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 application programs to communicate with existing IBM host applications using 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 performed 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 logging.

Management Services (MS)

The MS API allows a SNAplus2 application to communicate with other Management Services products 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) running on other computers to access a 3270 host computer over a SNAplus2 host connection. Both the SNAplus2 TN3270 program (provided as a separate package from the main SNAplus2 product) and other vendors' TN3270 programs are supported.

Remote Command Facility (RCF)

SNAplus2 provides facilities to allow an operator using the NetView program at a host to issue commands from the NetView console, either to manage SNAplus2 components or to issue HP-UX commands on the SNAplus2 computer.
