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
NCIXFATU. Refer to the corresponding installation step in Installing Natural CICS Interface
on z/OS in the Natural Installation
documentation.
The NCIXFATU 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 NCIXFATU module calls the NCIZNEP module through EXEC
CICS LINK, which performs a Natural session cleanup.
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.
