This document describes CICS 3270 Bridge support.
The following topics are covered:
By default, Natural CICS Interface supports the CICS 3270 Bridge by being able to deal with "bridged devices", that is, terminals which are emulated via a CICS 3270 bridge exit.
If you want full CICS 3270 Bridge support, you have to install the
NCI load module NCIXFATM
. Refer to the corresponding installation
step in Installing Natural CICS
Interface on z/OS in the Natural
Installation documentation.
The NCIXFATM
module is a CICS XFAINTU
Global User Exit (GLUE). Its purpose is to release Natural resources in case
the bridge facility's keep-time has expired and an associated Natural session
has not been terminated yet.
The NCIXFATM
module provides the same functionality for
Natural as a Node Error Program (NEP) provides for "real"
terminals.
When you are using the CICS 3270 Bridge, you are recommended to
start a Natural session with profile parameter DSC
=OFF
(data-stream compression for 3270-type terminals disabled) to force Natural
always to send full screens rather than the delta to the previous screen.
