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:
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.
