Configuring User Applications
8 Configuring User Applications
This chapter provides instructions for configuring SNA resources to support user applications that use any of the
following communication: 3270, RJE, 5250, and LUA. The SNA resources required by such applications include
LUs, session definitions, and user definitions.
For 3270, RJE, LUA, and dependent APPC communication, you must configure dependent LUs. For independent
APPC and 5250 communication, you can use the default control point LU (defined automatically when you configure
the local node) or define independent LUs.
Before you can configure the resources described in this chapter, you must perform the following configuration:
• Configure the node as described in Section 4.2,
Configuring the Node.
• Configure connectivity as described in Chapter 5, Defining Connectivity Components. For 3270, RJE, LUA, and
dependent APPC communication, you must configure the link to support dependent LU traffic. For independent
APPC and 5250 communication, the link must support independent LU traffic.
You do not need to configure a direct link to the host if you are using upstream PU concentration or DLUR.
For more information, see Section 9.2, Configuring PU Concentration and Section 5.3, Defining DLUR PUs.
The following list describes the configuration tasks required for each type of user application:
3270 applications
For 3270 communication, configure the following resources:
1. For a 3270 display or printer, define a dependent LU as described in Section 6.1, Defining LU Types 0–3.
2. To enable 3270 displays to select from a pool of LUs, define an LU pool as described in Section 6.2,
Defining LU Pools. If a display uses a dedicated LU, you can skip this step.
3. Define emulator users (or groups of users) and 3270 emulator sessions as described in Section 8.1,
Configuring 3270 Users and Sessions.
SNAplus2 provides 3270 emulation software that enables you to log on to and use SNA host systems from
your HP-UX computer. Using this software, you can transfer files between the local and host computers,
and control display and printer emulation sessions. You can customize some of the 3270 emulation features,
such as key mapping and display attributes. SNAplus2 3270 emulation also enables you to use HLLAPI
applications.
5250 applications
For 5250 communication, configure the following resources:
1. Configure the node for APPC communication:
a. If you can use the local node’s control point LU, you do not need to configure a local LU. If you
need a local LU definition (for example, to use session security), define the local LU as described in
Section 7.1, Defining Local LUs.
b. If the local node is a LEN node, you must define the AS/400 system as a remote node as described
in Section 7.2, Defining Remote Nodes.
If the local node is an APPN end node or network node, you can use the control point LU on the AS/
400 system as a partner LU, so you do not need to configure any other partner LUs.
You do not need to define any modes, because 5250 uses the standard mode
QPCSUPP.
2. Define emulator users (or groups of users) as described in Section 8.2, Configuring 5250 Users.
RJE applications
SNAplus2 provides support for remote job entry (RJE), enabling you to submit jobs to a host computer for
processing. The RJE workstation daemon handles transfer of jobs to the host, and also handles the output
returned from the host.
