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
“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 “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: For a 3270 display
or printer, define a dependent LU as described in “Defining LU Types 0-3”. To enable 3270 displays to
select from a pool of LUs, define an LU pool as described in “Defining LU Pools”. If a display uses
a dedicated LU, you can skip this step. Define emulator users (or groups
of users) and 3270 emulator sessions as described in “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: Configure the node
for APPC communication: 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 “Defining Local LUs”. If the local node is a LEN
node, youmust define the AS/400 system as a remote node as described
in “Defining Remote Nodes”. If the local node is an APPN end 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. Define emulator users (or groups
of users) as described in “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. 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. For RJE communication, configure the following resources: - LUA applications
To support an LUA application, configure the following
resources: Define a dependent
LU as described in “Defining LU Types 0-3”. To enable an LUA application
to select from a pool of LUs, define an LU pool as described in
“Defining LU Pools”. If the LUA application
uses a dedicated LU, you can skip this step.
An LUA application uses the LU 0-3 resources of the
node to communicate with a host application. You do not need to
define any additional resources.
