Natural supports the following 64-bit operating system platforms:
Red Hat Enterprise Linux 8 (x86-64)
SUSE Linux Enterprise Server 12 and SUSE Linux Enterprise Server 15 (x86-64)
Red Hat Enterprise Linux 8 (z/Linux)
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
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 |
|---|---|---|
| Red Hat Enterprise Linux 8 (x86-64) | 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 |
| Red Hat Enterprise Linux 8 (z/Linux) | gcc 4.8.1 | Red Hat Enterprise Linux 8: gcc 4.8.1 |
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.
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.
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.
