PRODUCT NAME: HP SNA Application Programming SPD 26.86.10

Interface for OpenVMS, Version 2.7

This SPD describes HP SNA Application Programming

Interface for OpenVMS, which is available for the Open-

VMS I64, OpenVMS Alpha and OpenVMS VAX plat-

forms. All information applies to all platforms unless

otherwise indicated.

DESCRIPTION

The HP SNA Application Programming Interface for

OpenVMS (API) is a layered software product that al-

lows user-written applications running on suitably con-

ﬁgured OpenVMS systems within a DECnet or TCP/IP

network or on suitably conﬁgured OpenVMS systems

within an OpenVMS SNA environment to exchange in-

formation with cooperating applications on an IBM host.

The API software exists in the OpenVMS system as a

shareable image. Access between the cooperating HP

and IBM applications is via one of the following SNA

server or gateway 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 DECnet SNA Gateway for Synchronous Trans-

port

• HP DECnet SNA Gateway for Channel Transport

• HP SNA Server for OpenVMS VAX , an OpenVMS

VAX layered product that supports local access as

well as remote DECnet clients

Features

The HP SNA Application Programming Interface for

OpenVMS (API) is a collection of subroutines designed

to provide an easy-to-use interface for the OpenVMS

application programmer who has a speciﬁc need to in-

terface to an IBM application subsystem. It supports

many different types of sessions between OpenVMS ap-

plications and applications running on an IBM host.

API implements all of the path control layer and por-

tions of the transmission and data ﬂow control layers of

SNA. The interface supports a number of different appli-

cations, each of which uses the SNA function manage-

ment, data ﬂow control, and transmission control layers

in a different way. API is not limited to supporting a par-

ticular application, such as 3270 terminals or Remote

Job Entry (RJE) workstations; the supported session

types are Logical Unit types 0, 1, 2, and 3, using the

FM and TS proﬁle types 3 and 4, as described in the

product documentation.

API provides extensive parameter checking, state ma-

chine management, and other high-level services, re-

lieving the OpenVMS application programmer of tedious

protocol details such as state machine processing or

"standard" SNA message format checking. The inter-

face appears to the OpenVMS application as a set of

subroutines that it calls to request the following opera-

tions:

• Establish an SNA session with an application running

on an IBM host
