HP-UX SNAplus2 R7 Administration Guide

Introduction to SNAplus2

SNAplus2 Components

• 3270 emulation programs (see Section 2.3.2, User Applications).

• 5250 emulation programs (see Section 2.3.2, User Applications).

• RJE workstation daemon (see Section 2.3.2, User Applications).

• APPC Application Suite (see Section 2.3.2, User Applications)

3270 Emulation

You can use 3270 emulation software to log on to and use SNA host systems from your computer, control display

and printer emulation sessions, and to transfer ﬁles between the local and host computers. 3270 emulation uses the

node’s LU type 0–3 resources.

To use 3270 emulation, you need to deﬁne the 3270 users on your system, identiﬁed by their login IDs, and the

3270 features available to each user or group of users. 3270 users and sessions are deﬁned as domain resources,

which simpliﬁes the conﬁguration required to support emulation across the domain.

The SNAplus2 3270 emulation program provides session control and ﬁle transfer capabilities. In addition, you can

customize some 3270 emulation features, such as key-mapping and display attributes. SNAplus2 3270 emulation

also enables you to use HLLAPI applications.

Refer to HP-UX SNAplus2 3270 User’s Guide for information about using the 3270 emulation software to

communicate with a host.

For more information about conﬁguring support for 3270 emulation, see Chapter 8, Conﬁguring User Applications.

5250 Emulation

Using 5250 emulation software, you can log on to and use AS/400 systems from your computer. You can use

emulation software to control display and printer emulation sessions and to transfer ﬁles between the local computer

and the AS/400. 5250 emulation uses the node’s LU type 6.2 resources.

Note

SNAplus2 does not provide a 5250 emulation program; it just provides support for third

party 5250 emulation software.

To use 5250 emulation with SNAplus2, you need to deﬁne the 5250 users on your system. 5250 users are deﬁned

as domain resources, which simpliﬁes the conﬁguration required to support emulation across the domain.

Depending on the requirements of the 5250 emulation program you use, you may need to conﬁgure the emulation

program with additional information.

For more information about conﬁguring support for 5250 emulation, see Chapter 8, Conﬁguring User Applications.

RJE Workstation Daemon

SNAplus2 provides support for remote job entry (RJE), enabling you to submit jobs to a host computer for processing.

The RJE workstation daemon is the SNAplus2 component that handles transfer of jobs to the host, and also handles

the output returned from the host.

You can prepare jobs for submission to the host and add them to the queue for an RJE workstation at any time,

regardless of whether the RJE workstation is running. When the workstation runs, it submits any outstanding jobs

to the host (in the order in which they were submitted). It also routes any output received from the host to the

appropriate destination, as determined by the conﬁguration.

The RJE workstation uses the node’s LU type 0–3 resources. In addition, you need to deﬁne (as domain resources)

the RJE workstations on your system.

The users of an RJE workstation can deﬁne workstation style ﬁles to supplement the SNAplus2 conﬁguration and

to control the operation of the workstation.
