PRODUCT NAME: HP SNA APPC/LU6.2 Programming SPD 26.88.12

Interface for OpenVMS, Version 2.6

This SPD describes the HP SNA APPC/LU6.2 Program-

ming Interface for OpenVMS, which is available for the

OpenVMS Operating System for OpenVMS I64, Open-

VMS Alpha and OpenVMS VAX platforms. All informa-

tion applies to all the platforms unless otherwise indi-

cated.

DESCRIPTION

The HP SNA Advanced Program-to-Program Commu-

nications/Logical Unit 6.2 (APPC/LU6.2) Programming

Interface for OpenVMS (the APPC product) is a lay-

ered software product that allows user-written applica-

tions running on suitably conﬁgured OpenVMS systems,

either within a DECnet or TCP/IP network or on suit-

ably conﬁgured OpenVMS systems within an OpenVMS

SNA environment to exchange messages with cooper-

ating applications in an IBM® host. The APPC software

exists in the OpenVMS system as a shareable image.

Access between the cooperating HP and IBM applica-

tions is via one of the following products:

TCP/IP or DECnet Connections

• HP SNA Peer Server

• HP SNA Domain Gateway

• HP SNA Access Server for Windows NT®

• HP SNA Server for OpenVMS Alpha, a layered prod-

uct that supports local access as well as TCP/IP and

DECnet clients

DECnet Only Connections

• HP SNA Gateway for Synchronous Transport

• HP DECnet SNA Gateway for Channel Transport

• HP SNA Server for OpenVMS VAX, a layered prod-

uct that supports local access as well as remote

DECnet clients

The APPC product is a set of subroutines that are called

by OpenVMS programs which act as LU6.2 transac-

tion application programs. These subroutines allow an

OpenVMS transaction application to:

• Activate and deactivate sessions

• Allocate and deallocate LU6.2 basic and mapped

conversations

• Send and receive data

• Request conﬁrmation and conﬁrm transactions

• Send and receive error information

•Deﬁne and delete local LU names and TP names

• Supply program initialization parameters

• Supply session-level security and inbound conversa-

tion level security

• Allow outbound conversation allocation

• Notify the user application of session failure

• Notify the user application of conversation dealloca-

tion (not applicable to HP SNA Access Server for

Windows NT®)

Features

The APPC product provides features to assist the user

in writing and executing the OpenVMS transaction pro-

gram. The APPC product performs the SNA commu-

nications function on the programmer’s behalf, allow-

ing the user to concentrate on solving the application
