1.9.5 Sun APPC
Advanced Program-to-Program Communication (APPC) allows programs on
peer systems to communicate with each other over an SNA network. Sun
APPC (SUNWappc) allows you use the SunLU6.2 Transaction Programmer's
Reference verbs or the Common Programming Interface for Communications
(CPI-C) calls to write APPC transaction programs (TPs) to interact with both
IBM mainframe and SNA peer applications. For more information, refer to the
SunLU6.2 Transaction Programmer’s Reference and SunLU6.2 CPI-C
documentation listed in “Related Sun Documents” in the Preface.
For SunAPPC clients, you must configure the following:
•
Local independent LU or local dependent LU. For information on
configuring an independent LU, refer to Section 9.1, “Configuring an
Independent LU,” on page 9-2. For information on configuring a dependent
LU, refer to Chapter 8, “Configuring Dependent LUs.”
•
Partner LU for the local LU. For more information, refer to Section 9.2,
“Configuring a Partner LU,” on page 9-4.
•
Session mode for the LU-LU pair. For more information, refer to Section 9.3,
“Configuring the Session Mode,” on page 9-7.
•
LU6.2 users that can access the local LU. For more information, refer to
Section 9.4, “Configuring an LUType 6.2 User,” on page 9-12.
•
Invocable TPs that are accessed by the local LU and the control operator TPs
that require special privileges. For more information, refer to Section 9.5,
“Configuring a Transaction Program,” on page 9-13.
Note – You can configure a TP for a specific local LU (Type 6.2) or for all local
LUs (Type 6.2). In addition, SNA service transaction programs, such as Change
Number of Sessions (CNOS), do not require a TP definition since they are
automatically defined.
If your Sun PU2.1 SNA Server is installed on multiple systems, you can
configure APPC on more than one of the systems. A networked TP can locate
the server it requires by using the Sun Name Server. The Sun Name Server
resolves requests for LU names to the system on which the local LU is
configured. For more information, refer to Section B.4, “Using the Sun Name
Server with APPC,” on page B-7.
