INPL Format

The installation instructions frequently refer to the Natural utility INPL. INPL is used to load the Natural system objects (dataset NATvrs.INPL) into the Natural system files (see below). For details of this utility, refer to the section INPL Utility in the Natural Utilities documentation.

Installation Options

Natural offers various installation options which affect the setting up of your Natural system. For example, you can decide whether or not to use a Natural global buffer pool, a Natural shared nucleus, etc.

These options are described in the Natural Operations documentation or in the Natural TP Monitor Interfaces documentation. You are recommended to read this information before you begin with the installation of Natural.

Before you install Natural-based subproducts in a new Natural Version 4.2 environment, refer to the corresponding subproduct-specific installation description regarding INPL procedures.

Natural System Files

Concerning the Natural system files, the following installation-related information applies:

FNAT

If you wish to upgrade from a previous Natural version, either a new FNAT system file can be used or the previous system file can be reused. For further information, see Migration Hints in the current Natural Release Notes for Mainframes.

FUSER

The FUSER system file can be used exclusively by the new Natural version or it can be shared by different versions of Natural. See the step Load the FUSER System File in the appropriate operating-system-specific installation documentation.

FDIC

The FDIC system file can be used exclusively by the new Natural version or it can be shared by different versions of Natural. See the step Load the FDIC System File in the appropriate operating-system-specific installation documentation.

FSEC

The FSEC system file can be used exclusively by the new Natural version or it can be shared by different versions of Natural. See the step Load the FSEC System File in the appropriate operating-system-specific installation documentation.

Using VSAM System Files

If you want to use the Virtual Storage Access Method VSAM for storing your system files, a supported version of Natural for VSAM is required.

For the supported versions, refer to Natural and Other Software AG Products in the current Natural Release Notes for Mainframes.

For further information on the Natural interface to VSAM, refer to the Natural for VSAM documentation.

It is possible to store the system files of different Software AG products on different data base management systems (for example, the Con-nect system file on Adabas and the Natural system file on VSAM). However, if Adabas is available, it is recommended that you use Adabas for all system files.

For information about which Software AG products can be used with VSAM system files, please contact Software AG support or your Software AG representative.

Using Installation Jobs Generated by System Maintenance Aid (SMA)

The installation of Software AG products is performed by installation jobs. These jobs are either created "manually" or generated by System Maintenance Aid (SMA) Version 2.1.2.

For each step of the installation procedures described below, the job number of a job performing the corresponding task is indicated. This job number refers to an installation job generated by SMA.

For information on the concepts and the usage of Software AG's System Maintenance Aid (SMA), refer to the System Maintenance Aid documentation and to SMA Readme Files.

SMA Readme Files:
For information on important parameters and options, refer to the SMA Function RM (Show Readme File) of the corresponding product.

Note:
System Maintenance Aid (SMA) is not available for the operating system VM/CMS.
