This Dokument 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 source module NCIXFATU. Refer to the corresponding
installation step in Installing Natural CICS
Interface on z/OS or
Installing
Natural CICS Interface on z/VSE in the Natural
Installation documentation.
The NCIXFATU module actually 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 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.
