This document of the Natural CICS Interface documentation describes the CICS 3270 Bridge support.
The following topics are covered:
By default, the 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.
