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 case a compiler version is used which is compatible according to the declaration of the compiler vendor, Software AG does not ensure that Natural works properly.

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.
