## Supported Platforms, Requirements, Product Availability, and End of Maintenance

You can view all available product versions and check the dates when their maintenance ends by using the System Requirements App at:

https://documentation.softwareag.com/systemrequirements/#/

Here, you can enter the product name or code in the search field and see the latest information on system requirements and product availability.

## Compilers Used to Build Natural

Natural was built and tested with the compilers listed below. When relinking Natural during the installation or using the `make` command, we strongly recommend that you use the same compiler version.

In the event that a compiler other than one of those listed below is used, it is not guaranteed that Natural will function properly. This applies even in the case that the compiler used is declared compatible to the listed compiler by its manufacturer and/or vendor.

Release Platform | Supported Compiler | Build Platform and Compiler
--- | --- | ---
Red Hat Enterprise Linux 8 (x86-64) | gcc 8.5.0 | Red Hat Enterprise Linux 8: gcc 8.5.0
Red Hat Enterprise Linux 9 (x86-64) | gcc 11.3.1-4 | Red Hat Enterprise Linux 8: gcc 8.5.0
SUSE Linux Enterprise Server 15 SP3 or above (x86-64) | gcc 8.5.0 | Red Hat Enterprise Linux 8: gcc 8.5.0
Red Hat Enterprise Linux 8 (z/Linux) | gcc 8.5.0 | Red Hat Enterprise Linux 8 (z/Linux): gcc 8.5.0

## Memory Space Requirements

The memory space required by Natural largely depends on the number of users.

The memory space per user is determined by the settings in the parameter file, especially by the values of profile parameters such as `USIZE` and `SSIZE`. By default, Natural is invoked with the parameter file `NATPARM`. However, you can also invoke Natural with an alternative parameter file (by specifying, for example, `PARM=myparm`).

In addition to the user-specific memory, memory is required for the buffer pool, which is shared among all users.

## Disk Space Requirements

Approximately 2 GB of hard-disk space is required for Natural (including all Natural and Installer packages). This value depends on the installation hardware. On some platforms, it is higher.

Another 250 MB of hard-disk space is required for Natural Security.

## Software Requirements for Using Related Natural Products

The following is required if you want to use related Natural products:

- Entire Access to access SQL databases.

- EntireX when using Natural RPC.

- Entire Net-Work to access remote Adabas database systems.

- Tamino when using Natural for Tamino.

- HTTP server, like Apache or IIS when using the Natural Web Interface.

Natural includes interfaces to:

- Adabas

- ApplinX

It is recommended that you use the latest versions of the above listed products. You can view all available product versions and check the dates when their maintenance ends by visiting https://empower.softwareag.com/. Go to Products > Product Version Availability.

## Software Requirements for Natural Security

Natural Security requires:

- Natural (same version and update package or fix as that of Natural Security).

- Adabas.

- Entire Net-Work. Only required if the `FSEC` system file is located in a remote database. See also Using Natural Security on Multiple Platforms in the Natural Security documentation.
