System Requirements

This document covers the following topics:

Supported Operating System Platforms

Natural supports the following 64-bit operating system platforms:

  • AIX 7.1

  • AIX 7.2

  • Red Hat Enterprise Linux 7 (x86-64 and z/Linux)

  • Red Hat Enterprise Linux 8 (x86-64 and z/Linux)

  • Oracle Solaris 11.3 (Sun and FSC)

  • Oracle Solaris 11.4 (Sun and FSC)

  • SUSE Linux Enterprise Server 12 (x86-64)

  • SUSE Linux Enterprise Server 15 (x86-64)

  • CentOS Linux 7 (x86-64)

Special considerations concerning Oracle Solaris 11.3

  • Oracle Solaris 11.3 is a prerequisite for Natural 9.1.3 because Natural was built on Solaris 11.3 using Oracle Developer Studio 12.6.

  • Since Oracle guarantees binary compatibility, Natural 9.1.3 will also operate on Solaris 11.4 and subsequent releases.

  • If you need to relink Natural, Oracle Developer Studio 12.6 is also required.

  • You must relink Natural if you have implemented your own user exits or if specific drivers, such as Entire Access (OSX), are used by Natural.

  • Oracle's binary compatibility also applies to custom compiled output of Oracle Development Studio 12.6.

    The compiled output also can be executed on Solaris 11.4 and subsequent releases.

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, Software AG cannot guarantee 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
AIX 7.1 IBM XL C/C++ Compiler Version 13 AIX 7.1: IBM XL C/C++ Compiler Version 13
AIX 7.2 IBM XL C/C++ Compiler Version 13 AIX 7.1: IBM XL C/C++ Compiler Version 13
Red Hat Enterprise Linux 7 (x86-64 and z/Linux) gcc 4.8.5 Red Hat Enterprise Linux 7: gcc 4.8.5
Red Hat Enterprise Linux 8 (x86-64 and z/Linux) gcc 4.8.5 Red Hat Enterprise Linux 7: gcc 4.8.5
SUSE Linux Enterprise Server 12 (x86-64) gcc 4.8.5 Red Hat Enterprise Linux 7: gcc 4.8.5
SUSE Linux Enterprise Server 15 (x86-64) gcc 4.8.5 Red Hat Enterprise Linux 7: gcc 4.8.5
Oracle Solaris 11.3 Oracle Developer Studio 12.6 C, C++ Compiler Oracle Solaris 11.3 64 bit: Oracle Developer Studio 12.6 C, C++ Compiler
Oracle Solaris 11.4 Oracle Developer Studio 12.6 C, C++ Compiler Oracle Solaris 11.3 64 bit: Oracle Developer Studio 12.6 C, C++ Compiler
CentOS Linux 7 (x86-64) gcc 4.8.5 Red Hat Enterprise Linux 7: gcc 4.8.5

Important Information for Oracle Solaris

If link problems occur on a machine with multiple compilers, make sure to use the required compiler by setting the environment variable CC to the correct path for the installation process.

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.

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 Software AG products. You can view all available Software AG product versions and check the dates when their maintenance ends by visiting Software AG's Empower web site at 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.

Additional Software Requirements

Additional Software Requirements for Red Hat Enterprise Linux Server 8

Before installing Natural on your machine, you must first install the service librarylibnsl. Natural uses libnsl.so.1. Please ensure that the appropriate package is installed. You can do that by running the command: 

yum install libnsl
