This document describes how to install the CICS connection for a Natural Development Server (NDV) running under SMARTS on z/VSE.
The following topics are covered:
For details, refer to the section Prerequisites.
To install the Natural Development Server CICS Adapter, perform the following steps:
(Job I005, Step 8405)
The Natural Development Server sublibrary must be defined in the CICS Libdef search chain.
Customize the standard listener EZAL of the CICS socket
interface using the CICS transaction EZAC,DISplay,LISTENER and, on
the second screen, define NATUXRFE in the SECEXIT
field of EZAL.
The definition of SECEXIT=NATUXRFE is mandatory when the
NDV server ist started with impersonation (parameter
SECURITY_MODE).
As of z/VSE Version 4.1, the CICS task related user exit must
be active (transaction EZAT).
Start the standard listener using the CICS transaction
EZAO.
The following CICS resource definitions are required:
Define the CICS transaction for the remote front-end. This
transaction name is an arbitrary name which must be defined in the NDV
configuration parameter RFE_CICS_TA_NAME. This document
uses the transaction name NRFE.
DEFINE TRANSACTION(NRFE) GROUP(ndvgroup)
PROGRAM(NATCNRFE)
TWASIZE(128)
RESART(NO)
TASKDATAKEY(USER)
TASKDATALOC(ANY)
Define the programs NATCNRFE and
NATLRGND.
DEFINE PROGRAM(NATCNRFE) GROUP(ndvgroup)
LANGUAGE(C) DATALOCATION(ANY) EXECKEY(USER)
*
DEFINE PROGRAM(NATLRGND) GROUP(ndvgroup)
LANGUAGE(C) DATALOCATION(ANY) EXECKEY(USER)
Note:
If CICS runs with storage protection, NATCNRFE must
be defined with EXECKEY=(CICS).
Define the program NATUXRFE.
DEFINE PROGRAM(NATUXRFE) GROUP(NWOgroup) LANGUAGE(C) DATALOCATION(ANY) EXECKEY(CICS)
(Job I054, Step 8420)
The NDV object modules must be linked with the necessary runtime extensions of your CICS installations into executable load modules.
In order to dispatch the NDV Natural sessions in CICS, you must adapt the configuration file of your development server running under SMARTS on z/VSE. For this purpose, one sample JCL member (SMAI009 Step 8410) is available.
