Before beginning the installation process, consider the following:
Be sure to read the current Natural Release Notes for Mainframes for information on software and hardware requirements, known issues and changes to the documentation. These Release Notes apply to base Natural and Natural add-on products.
A supported version of the operating system on which Natural is to run must be installed. For the supported operating systems and versions, refer the Product Version Availability section of Software AG's Empower web site at https://empower.softwareag.com/.
A supported version of the TP monitor/online interface used with Natural must be installed. For the supported versions, refer to TP Monitors/Online Interfaces in the current Natural Release Notes for Mainframes.
A supported version of Adabas must be installed to store the Natural system files. See also Natural System Files.
For the supported versions, refer to Database Management Systems in the current Natural Release Notes for Mainframes.
A supported version of each database management system used to store the user data processed with Natural must be installed.
For the supported versions, refer to Database Management Systems in the current Natural Release Notes for Mainframes.
The installation medium (for example, tape or CD-ROM) distributed for Software AG mainframe products contains all files required to install base Natural and the Natural add-on products.
The software required for the optional Natural components are contained in the files supplied for base Natural. The software required for the Natural add-on products are contained in separate product files which are listed in the product-specific sections of the Installation for BS2000 documentation. In addition to the product files, the installation medium can contain the latest fix updates for the supplied products.
The names of the product files begin with a product code that identifies each product, as in the following table:
|Product Code||Product Name|
|ETP||Entire Transaction Propagator|
|NAF||Natural Advanced Facilities|
|NOC||Natural Optimizer Compiler|
|NRT||Natural TIAM Interface|
|NUT||Natural openUTM Interface|
Each installation medium is delivered with a Software AG Product Delivery Report providing the following information:
A list of all files contained on the medium.
The sequence in which the files are located on the medium.
Attribute descriptions of each file.
The installation of Software AG products on BS2000 is performed by installation jobs that contain the JCL required to identify the job to the operating system and run the job.
There are two methods for creating and running the installation jobs:
using the jobs generated by System Maintenance Aid (SMA), or
using the jobs created from the sample installation jobs provided.
The Installation for BS2000 documentation solely describes the installation procedure for the jobs generated by SMA. If you do not use SMA for installation, refer to the example installation jobs supplied on the installation medium.
SMA is supplied with base Natural.
For each step of the installation procedure, System Maintenance Aid (SMA) generates an installation job according to your specifications in SMA. You then submit and run the generated job.
Before you can start generating the jobs, you have to load the
SMT111.TABS file from the
installation medium into the SMA system file.
SMT111.TABS contains the tables SMA
requires to build the jobs.
SMA is supplied with base Natural. For instructions on loading the file and using SMA, refer to the System Maintenance Aid documentation.
For installation guidance and information on new or changed SMA parameters and Natural features, you can view the product-specific Readme files by using the appropriate SMA function.
To view a product-specific Readme
From the product list on an SMA Maintenance
screen, execute the
RM (Show Readme
File) command for the required product(s).
The sample installation jobs that can be used as an alternative to SMA
are provided in an
LMS library contained on the file
shipped on the installation medium. All sample installation jobs provided are
listed and described in the README document that accompanies the shipment.
You need to adapt the sample installation jobs to your requirements.
Each installation job indicates the
product code and
version (for example,
the corresponding product (for example, Natural).
Each step of the installation procedure is identified by a job name (for
I050) and one or more steps (for example, Steps
0101 for Job
indicate the tasks performed by the job. The job name can have a prefix such as
a product code (for
A sample installation job from the LMS library can also have a
suffix letter which indicates a variant of the job. For example: Job
I060L is a variant of Job
I060 and used if support of
the IBM Language Environment (LE) is required. In SMA, the same variant is
executed with Job
I060 and the appropriate SMA parameter
The installation process comprises the following:
Creating the Natural system files.
Creating the Natural parameter module.
Creating the Natural nucleus.
Loading the Natural objects.
Installing the optional Natural components.
Installing the Natural add-on products.

Verify the successful completion of the installation by starting Natural and testing the system functions as described in the relevant sections of the Installation for BS2000 documentation.
If Natural Security is installed, certain Natural functions and libraries can be restricted to specific users.
The installation instructions frequently refer to the Natural INPL
utility which is used to load the files (for example,
NATvrs.INPL) contained on the Natural
installation medium into the Natural
system files. The INPL utility is invoked with the Natural system
INPL. For detailed information on the
INPL utility, refer to the
The Natural nucleus consists of two functional parts: the environment-independent nucleus and the environment-dependent nucleus.
If you maintain different versions of Natural, you must use distinctive names for the nuclei to identify each version.
This section covers the following topics:
The environment-independent nucleus contains components that are independent of the operating system or TP system (online interface) being used. The same instance of the environment-independent nucleus can be used in different online and batch environments in different tasks. The environment-independent nucleus is reentrant.
The environment-independent nucleus can reside in a common memory pool (CMP) or in Class 4 Memory where it can be shared between different tasks.
A module (such as the environment-independent nucleus) loaded into a CMP or Class 4 Memory is protected against modification. Therefore, tests for modifications of the environment-independent nucleus should be performed in a separate environment.
If the environment-independent nucleus resides in the CMP or Class 4 Memory, multiple batch jobs or TP tasks (for example, TIAM) share the same instance of the environment-independent nucleus. This results in a significant reduction of paging activities and virtual storage consumption.
- Modules for Linking
The following modules must be linked to the environment-independent nucleus:
Modules for base Natural
Environment-independent modules of Natural add-on products
Environment-independent user-supplied modules
When using System Maintenance Aid (SMA), the required modules are linked to the environment-independent nucleus during the appropriate installation job/step. Modules that can optionally be linked are mentioned in the Installation Procedure.
The installation of the environment-independent nucleus is described in Link the Nucleus in the Installation Procedure.
- Specifying the Nucleus Name
The name of the environment-independent nucleus to be used is specified with the Natural profile parameter
NUCNAMEin the Natural parameter module during the installation of the environment-dependent nucleus. You can specify
NUCNAMEas a dynamic parameter in the primary parameter input, but you cannot specify
NUCNAMEin the input strings of the Natural profile parameter
The Natural parameter module is described in Building a Natural Parameter Module in the Operations documentation.
SYSare described in the Parameter Reference documentation.
If you maintain different versions of Natural, we recommend that you use distinctive names for the nucleus to clearly identify each version and environment, for example:
NAT824for the environment-independent nucleus,
NAT824Cfor the environment-dependent nucleus for a CICS interface, and
NAT824Bfor the batch environment.
- Rules for Using an Environment-Independent Nucleus
The rules that apply when using the environment-independent nucleus are described in the following section.
Concerning openUTM, see also Several Applications with one Common Natural in the TP Monitor Interfaces documentation.
The environment-independent nucleus is linked without the corresponding reentrant parts of the batch, TIAM and openUTM drivers (these modules must be linked to the environment-dependent nucleus).
Example: The name of the environment-independent nucleus is
NATSHARE./START-PROGRAM $BINDER START-LLM-CREATION INTERNAL-NAME=NATSHARE, - SLCE-DEFINITION=*BY-ATTRIBUTES(RESIDENCY-MODE=*YES) INCLUDE-MODULES NATINV,LIB=(NATvrs.MOD) . . INCLUDE-MODULES NATURAL,LIB=(NATvrs.MOD) . . INCLUDE-MODULES NATLAST,LIB=(NATvrs.MOD) MODIFY-SYMBOL-ATTRIBUTES ADD-MODE=*31,RES-MODE=*ANY,READ-ONLY=*NO MODIFY-SYMBOL-VISIBILITY - SYMBOL-NAME = *ALL, - SYMBOL-TYPE = *DEFINITIONS, - VISIBLE = *NO(KEEP-RESOLUTION=*YES) SAVE-LLM LIB=NATURAL.USER.MOD END
vrsis the current product version of Natural.
Batch, TIAM and openUTM application-specific Natural parameter modules are also linked to the environment-dependent nucleus. In addition, the environment-independent nucleus can contain a common Natural parameter module, for example, for
CSTATICentries. The name chosen for the linked environment-independent nucleus is also identical with the name of the global common memory pool into which Natural is loaded. This name is to be used as operand for the following keyword parameters:

Example:NRTSTART NAMTIAM CODE=FRONT, NUCNAME=NATSHARE PARMODE=(31,ABOVE), . . NUTFRONT NATUTM APPLNAM=NATUTM, . . NUCNAME=NATSHARE PARMODE=(31,ABOVE)
The environment-independent nucleus is started by the program
Example:/EXEC (CMPSTART,NATURAL.MOD) NAME=NATSHARE,SIZE=2MB,POSI=ABOVE,ADDR=250,SCOP=GLOBAL PFIX=YES,LIBR=NATURAL.USER.MOD
The link to the environment-independent nucleus is created in the batch, TIAM or openUTM applications through the generation of the macro
BS2STUB; refer to CMPSTART Program described in the Operations documentation.
Example:NRTSTUB BS2STUB PARMOD=31,PROGMOD=ANY ADDON NAME=NATSHARE, STAT=GLOBAL NUTSTUB BS2STUB PARMOD=31,PROGMOD=ANY ADDON NAME=NATSHARE, STAT=GLOBAL
The environment-dependent nucleus must contain the reentrant part of the corresponding driver (
Example for TIAM:/START-PROGRAM $BINDER START-LLM-CREATION INTERNAL-NAME=NRTFRONT, - SLICE-DEFINITION=*BY-ATTRIBUTES(RESIDENCY-MODE=*YES) INCLUDE-MODULES NRTFRNT,LIB=(user-lib) /* Non-reentrant part of NAMTIAM INCLUDE-MODULES NRTRENT,LIB=(user-lib) /* Reentrant part of NAMTIAM INCLUDE-MODULES NRTSTUB,LIB=(user-lib) /* BS2STUB INCLUDE-MODULES nat-parm-module,LIB=(user-lib) /* ...

END
vrsis the current product version and
user-libis the name of the user library,
nat-parm-moduleis the Natural parameter module.
The environment-dependent nucleus contains components that depend on the operating or TP system being used.
In addition to the environment-independent nucleus, every single task in which Natural runs requires an environment-dependent nucleus containing modules that perform actions specific to the operating or TP system. The environment-dependent nucleus assumes control from the operating or TP system at the start of a Natural session, loads the environment-independent nucleus and passes control to it.
The following modules must be linked to the environment-dependent nucleus:
Environment-specific Natural interface modules
Environment-specific work file and print file modules
Environment-specific Natural parameter module (see also Building a Natural Parameter Module in the Operations documentation)
Environment-dependent modules of Natural add-on products
Adabas link routine (
Environment-dependent user-supplied modules defined as
CSTATIC in the Natural parameter module. The Natural profile
described in the Parameter Reference documentation.
When using System Maintenance Aid (SMA), the required modules are linked to the environment-dependent nucleus during the appropriate installation job/step. Modules that can optionally be linked are mentioned in the Installation Procedure.
The installation of the environment-dependent nucleus is described in Link the Nucleus in the Installation Procedure.
Both the Natural configuration module
(described in the Operations documentation) and the
Natural parameter module contain the Natural-supplied list of additional
modules to be statically linked to the nucleus.
The Natural parameter module also contains the user-supplied list of
additional modules to be statically linked to the nucleus as specified with the
Natural profile parameter
Each entry of these lists consists of a program name and a V-type address constant which must be resolved by linking the corresponding module to the Natural parameter module.
The Natural-supplied list provided with
is used if the Natural parameter module is not linked to the
environment-independent nucleus. If modules are statically linked to the
environment-independent nucleus, a Natural parameter module that defines all
these modules must also be linked to the environment-independent nucleus.
Optionally, you can specify an alternative Natural parameter module by
using the Natural profile parameter
PARM (described in
the Parameter Reference documentation). An alternative
parameter module takes precedence over a parameter module that is linked to
either the environment-independent or the environment-dependent nucleus.
During initialization of a Natural session, up to three lists of
statically-linked modules (specified with the Natural profile parameter
CSTATIC) are merged:
Base list for the merge is the list of the Natural parameter module
specified with the Natural profile parameter
V-type address constants not resolved in this list are resolved using the Natural parameter module linked to the environment-dependent nucleus;
V-type address constants not yet resolved are resolved using the Natural parameter module linked to the environment-independent nucleus.
If a user-supplied module is to be statically linked to the
environment-independent nucleus, it must be specified in the Natural parameter
module linked to the environment-independent nucleus as well as in the Natural
parameter module specified with the Natural profile parameter
When initializing a Natural session, you can also dynamically load the modules (supplied by Software AG or user-defined) that have been defined for static linking. For information on whether the module of a Natural add-on product is suitable for dynamic loading, read the documentation for your specific Natural add-on product.
For information on defining external names for static non-Natural
programs and dynamic linking and controlling these programs, see the Natural
described in the Parameter Reference documentation.
If a module is not defined for static linking, Natural attempts to load
and execute the module using environment-dependent functions
when the corresponding Natural
CALL statement is
The Natural system files are stored in an Adabas database.
The table below lists and describes the Natural system files that are usually available in a Natural environment. The availability of the system files and the data contained in the files depends on the Software AG products installed in addition to base Natural.
The settings for the system files are defined with Natural profile parameters of the same names (exception: scratch-pad file). You can follow the hyperlinks in the table below to read details about these parameters in the Parameter Reference documentation.
|System File||Supplied with||File Contents|
||Base Natural||All objects required for Natural system applications.|
||Base Natural||User-specific objects required for user-defined applications.|
||Base Natural||Parameter profiles specified by the profile
|Scratch-pad file||Base Natural||Data that is not stored explicitly as a Natural object in another system file. See also Natural Scratch-Pad File in the Operations documentation.|
||Base Natural||Natural Data Definition Modules (DDMs).
If Predict is installed,
If the Natural Development Server is installed,
||Base Natural||Registry data that is not stored explicitly in another system file.|
||Natural Security||Control information required for security definitions.|
||Natural Advanced Facilities||Control and spooling information required to output a report on a screen or printer and obtain print statistics.|
Like all other system files of Software AG products, the scratch-pad file is a logical file. The logical file number of the scratch-pad file is 212.
Since there is no mnemonic for the scratch-pad file such as
FDIC, it has to be
