Prerequisites

This document describes the prerequisites that apply when you install a Natural Development Server (product code NDV) on z/OS.

The following topics are covered:

General Prerequisites for NDV Installation

  • The currently applicable version of Natural for z/OS must be installed; refer to https://empower.softwareag.com/.

    Important
    Any user-written exits not written in Natural and used within a Natural Development Server environment must be reentrant and thread-safe (capable to run in a multi-tasking environment).

  • If you are using Predict and you have to migrate to a Predict version specified under Available and Supported Product Versions in the current Natural Release Notes for z/OS, you are strongly recommended to migrate to the newer Predict version before you install the Natural Development Server.

    Important
    If you do not migrate to a Predict version specified under Available and Supported Product Versions in the current Natural Release Notes for z/OS before starting the Natural Development Server installation, you will have to define a new Natural system file FNAT and a new Development Server File (FDIC). The current version of Natural for z/OS and the desired additional products must have been loaded on the Natural system file FNAT before you start the installation of the Natural Development Server.

  • To use other products in conjunction with the Natural Development Server, refer to the section Product Versions Supported by Natural in the current Natural Release Notes for z/OS for the required version.

  • The Software AG Editor must be installed. You are recommended to set the size of the editor buffer pool to 1024 KB.

    If you are using System Maintenance Aid (SMA), the necessary modules are linked when the SMA parameter SAG-EDITOR is set to Y (Yes). This is the default.

    If you are installing without SMA, see Installation for z/OS, Installing Software AG Editor.

  • The prerequisites for the operation of a remote development client must be fulfilled in addition. Natural for Windows or NaturalONE must have been installed on the PC client. For information on the applicable version of Natural for Windows, refer to https://empower.softwareag.com/.

  • Natural Development Server Version 9.2 is compatible with all supported versions of Natural for z/OS, Natural for Windows and NaturalONE.

Note
For information about plug-ins and add-on products available, refer to https://empower.softwareag.com/ and the section Available and Supported Product Versions in the current Natural Release Notes for z/OS.

Prerequisites for NDV for z/OS (Com-plete)

In addition to the general prerequisites described above, the following operating-system-specific prerequisites apply:

  • z/OS must be installed.

    Version as specified under Operating/Teleprocessing Systems Required in the current Natural Release Notes for z/OS.

  • Com-plete must be installed (product code COM).

  • The Natural Com-plete/SMARTS Interface must be installed (product code NCF).

  • To prevent the formation of endless loops in user programs running under NDV, specify a reasonable value for the CPU time limit in the SMARTS parameter THREAD-GROUP.

  • As a prerequisite for using the client impersonation feature (parameter SECURITY_MODE), Natural Security must be installed.
