System Requirements

This document covers the following topics:

Supported Operating System Platforms

Natural supports the following 64-bit operating system platforms, both for the Natural development environment (Natural) and for the Natural runtime environment (Natural Runtime):

  • Microsoft Windows 10 Professional and Enterprise

  • Microsoft Windows Server 2012

  • Microsoft Windows Server 2016

Home Editions of Microsoft Windows are not supported.

Notes:

  1. We suggest that you install all of the recommended and important Microsoft Windows updates before you start the installation.
  2. On Windows Server 2012 R2 the installation will fail if the Microsoft update KB2919355 is missing.

Compiler Used to Build Natural

Natural was built and tested with the following compiler:

  • Microsoft Visual Studio 2015

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 Software AG 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.

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

  • Entire Access to access SQL databases.
