This section describes how to define the NATPARM for Natural Business Services.
Job I060
To create a reentrant Natural nucleus for batch:
Notes:
The Business Service Administration subsystem uses special files that must be identified to the Natural transaction used for the subsystem. You can either use the LFILE parameter to dynamically identify the files or you can code the NTLFILE macro in the Natural parameter module to make the files part of the Natural nucleus.
To update your parameter module (NATPARM)
Set ADAPRM=ON in your NATPARM to define a reentrant
batch nucleus.
Set LFILE=(227,DBID,FNR) for the Natural
Construct data file (required for Natural Business
Services).
Note:
If you are installing Natural
Construct only, steps 3 and 4 are optional.
Set LFILE=(135,DBID,FNR) for secured data file to
invoke Natural.
Set LFILE=(136,DBID,FNR) for unsecured data file to
invoke Natural.
The DBID and FNR values identify the database and file number for the Business Service Administration subsystem file.
This step differs, depending on whether you are an z/OS or z/VSE user. For details on how to create the module, refer to your Natural installation and operations documentation.
Notes:
The following example shows a NATPARM profile for the Business Service Administration subsystem:
ACMPARM TITLE 'NATURAL 8.2 PARM-MODUL, EXAMPLE'

DBID=XXX, NATURAL SYSTEM FILE DB -
FUSER=(XXX,X), NATURAL USER SYSTEM FILE DB -

NTLFILE 136,ddddd,fffff BUSINESS SERVICES UNSECURED DATA
END
where:
ddddd is the physical database ID
fffff is the physical file number
The recommended Natural parameter settings are:
ESIZE=120
RUNSIZE=40
ADAPRM=ON
NTLFILE
227,ddddd,fffff
NTLFILE
135,ddddd,fffff
NTLFILE
136,ddddd,fffff
Note:
We recommend that you use a global buffer pool. If you use a local
buffer pool, changes to code are not automatically detected; new or updated
modules are not updated. If you are using a local buffer pool, stop and then
use the global buffer pool to restart all running services and update the
module.
To make the nucleus reentrant
Link the new batch nucleus with a reentrant version of the Adabas link routine.
Because you cannot make ADAUSER reentrant, you must replace it with one of the following:
Link the nucleus using the reentrant version of the link routine, ADALNKR, which is supplied with Adabas
or
Modify your existing ADALNK to be reentrant and then link the nucleus using the modified ADALNK
In either case, set the default SVCNR value in the ADALNK source to the Adabas SVC number used in your environment. In the multi-tasking batch nucleus, you cannot change ADARUN parameters dynamically because the DDCARD input parameters are no longer available.
Note:
For z/OS users, ensure that the RENT link option is
specified.
Job I055, Step 1370
To make the ADALNK routine reentrant
Set the &RENT macro value to 1.
For example, comment out the default setting for &RENT and remove the comment marker from the reentrant setting:
* &RENT SETB 0 Non-reentrant ADALNK .sg62. &RENT SETB 1 Reentrant ADALNK .sg62.
Assemble the modified ADALNK.
If running under z/OS, link the modified ADALNK.
Ensure the RENT link option is specified.
Using the Natural link job (I060) that linked the standard Natural nucleus, create an executable Natural nucleus. Include the NATPARM parameter module assembled and linked in Define the NATPARM.
Note:
Some components of Natural Construct
require access to the Software AG editor. Ensure that the editor is installed
and operational.
Using the Natural link job (I080) that linked the standard Natural nucleus, create an executable Natural nucleus. Include the NATPARM parameter module assembled and linked in Define the NATPARM.
Notes:
If you are using Natural Security, you must add definitions for the following libraries to Natural Security:
| Library | Description |
|---|---|
| SYSBIZ | Stores the executable code for the Business Service Administration subsystem. This library is not required if you are only installing Natural Construct. |
| SYSCST | Contains the generator maintenance facilities for Natural Construct. |
| SYSCSTX | Contains sample exit routines. |
| SYSBIZDE | Contains the Natural Business Services demo application for Adabas. This library is not required if you are only installing Natural Construct. |
| SYSCSTDE | Contains the Natural Construct demo application for Adabas. |
| SYSCSTD2 | Contains the Natural Construct demo application for DB2. |
| SYSCSTDV | Contains the Natural Construct demo application for VSAM. |
You can restrict access to these libraries to only those users who maintain the definitions that control the generation process. Users who generate modules or maintain help text using Natural Construct do not require access to the libraries.
The Adabas demo library for Natural Business Services (SYSBIZDE) contains examples of how to use the supplied models. It should be accessible to all developers.
Note:
The SYSBIZDE library includes all the modules in the Natural
Construct demo library (SYSCSTDE). If you are installing Natural
Construct without Natural Business Services, you must define
SYSCSTDE to Natural Security.
The modules in this library access the following DDMs:
NCST-CUSTOMER
NCST-INS-POLICY
NCST-ORDER-DISTRIBUTION
NCST-ORDER-HEADER
NCST-ORDER-LINES
NCST-PRODUCT
NCST-WAREHOUSE
These files should be publicly available.
To allow programs that access the Natural Construct help file to be recataloged, define the following DDMs to Natural Security:
NCST-HELP
NCST-HELP-LINES
NCST-PROFILE
The DB2 demo library (SYSCSTD2) contains examples of how to use the supplied models. It should be accessible to all developers. The modules in this library access the following DDMs:
NCSTDB2-CUSTOMER
NCSTDB2-ORDER_DISTRIBUTION
NCSTDB2-ORDER_HEADER
NCSTDB2-ORDER_INSTRUCTIONS
NCSTDB2-ORDER_LINES
NCSTDB2-PRODUCT
NCSTDB2-WAREHOUSE
The VSAM demo library (SYSCSTDV) contains examples of how to use the supplied models. It should be accessible to all developers. The modules in this library access the following DDMs:
NCSTVSAM-CUSTOMER
NCSTVSAM-ORDER-DISTRIBUTION
NCSTVSAM-ORDER-HEADER
NCSTVSAM-ORDER-LINES
NCSTVSAM-PRODUCT
NCSTVSAM-WAREHOUSE
To simplify and automate the launching of the Natural Business Services environment, use the Natural SYSPARM utility to create a new profile.
To create a new Natural profile
Log on to the SYSPARM library.
Issue the MENU command.
Type "A" in conjunction with the SYSBIZ profile name.
Add the parameters to start Natural with the required sizes and system files.
Note:
If suitable values are already linked to your
Natural nucleus, some of these parameters may not be
necessary.
If not defaulted in the Natural transaction, the following parameters are required:
| Parameter | Description |
|---|---|
| ESIZE=120 | Extended user area. |
| EDPSIZE=n | Memory required for the Software AG editor (when not using an editor work file and buffer pool), where n is conditional on the size of the program generated and the number of fields in the file. |
| RUNSIZE=40 | Size of the Natural runtime buffer. |
| LFILE=(227,DBID,FNR) | Natural Construct system file. |
| LFILE=(135,DBID,FNR) | Natural Business Services secured file (required for Natural Business Services installation). |
| LFILE=(136,DBID,FNR) | Natural Business Services unsecured file (required for Natural Business Services installation). |
To allow Natural Business Services to communicate with Natural
Security
Access the Natural Security main menu.
Access the Administration Services main menu.
Access the General Options menu.
Set the Free access to functions via interface subprograms property to "Y".
