Installation Procedure

To install the Natural Development Server CICS Adapter, perform the following steps:

Step 1: Customize CICS

(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)

Step 2: Link the object modules into the NDV load library

(Job I054, Step 8420)

The NDV object modules must be linked with the necessary runtime extensions of your CICS installations into executable load modules.

Step 3: Customize the Development Server

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.
