Configuring APPC Communication

Overview

Overview
APPC applications, 5250 emulation programs, and CPI-C applications
all require that you configure APPC first. An APPC application uses the
node's LU type 6.2 resources to communicate with another APPC or
CPI-C application on a host or peer computer, using a specified mode.
If the applications use CPI-C, you may need to do additional CPI-C
configuration after configuring APPC. A CPI-C application uses the
node's LU type 6.2 and mode resources to communicate with another
APPC or CPI-C application on a host or peer computer. You define the
same resources for a CPI-C application as for an APPC application. In
addition, if the TP on the SNAplus2 computer is the invoking TP (the TP
that starts the conversation), you may need to define one or more side
information entries for it, as described in "Defining CPI-C Side
Information". Each of these entries provides information on a partner
TP, the LU and mode resources used to access it, and any security
information required.
The configuration steps for APPC depend on whether the LU 6.2 traffic is
dependent or independent. Unless the remote node is a host, you must
use independent traffic. If the remote node is a host, you can use either
dependent or independent traffic.
Before you can configure APPC communication, 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."
In an APPN network, a single link station to an adjacent network node
NOTE
can be used to communicate with any remote node in the network, so you
do not need to configure a separate link station to each remote node.
In many cases, APPC applications can use the control point LU on both
the local and remote nodes, and a standard mode. In this case, your
configuration is ready for APPC without any further configuration.
The following steps can be used to configure APPC communication on the
local node. Depending on the types of the local and remote nodes, and on
your application, you may not need to perform these steps.
