This section describes step by step how to install Natural for MBCS (product code NKA) under the operating system VM/CMS using Adabas system files.
This section covers the following topics:
See also VM/CMS Environment in the Operations documentation.
For installation-related information on Unicode and code page support, refer to Configuration and Administration of the Unicode/Code Page Environment in the Unicode and Code Page Support documentation.
If used in the following section, the notation vrs or vr stands for the relevant version, release, system maintenance level numbers. For further information on product versions, see Version in the Glossary.
Base Natural must be installed.
For further information, refer to the products and versions specified under Natural and Other Software AG Products and Operating and Teleprocessing Systems Required in the current Natural Release Notes for Mainframes.
The installation tape was created under z/OS; it has standard z/OS labels and headers. It contains the datasets listed in the table below. The sequence of the datasets is shown in the Report of Tape Creation which accompanies the installation tape.
| Dataset Name | Contents |
|---|---|
NKAvrs.TAPE |
CMS installation material. This dataset is in TAPE DUMP format and must be loaded onto the installation mini disk. |
NKAvrs.INPL |
Natural system objects. |
Create the
.NKAvr.NKAvrs
directory and copy the file NKAvrs.TAPE
from the tape into this directory. As an alternative, define a minidisk for NKA
and load NKAvrs.TAPE onto the disk by
using the following command:
TAPE LOAD * * fm
If the sequence number of
NKAvrs.EXEC, as shown by the
Report of Tape Creation, is n,
you must position over 3 n - 2 tape marks (that is,
FSF 1 for the first dataset, FSF 4 for the second,
etc.). fm is the filemode used for the directory or
minidisk.
CREATE DIRECTORY .NKAvr.NKAvrs ACCESS .NKAvr.NKAvrs B TAPE REW TAPE FSF n TAPE LOAD * * fm
Modify NAT$LOAD EXEC: delete the comment for NKA to include
NKANUC TEXT. Example:
LOADLIST = LOADLIST 'NKANUC'
Build a new Natural module or a Discontiguous Shared Segment (DCSS) by
executing NATBLDM or NATBLDS respectively.
If the tape drive used when copying the contents of the installation
tape to disk was detached from your virtual machine, ask the system operator to
attach a tape drive to your virtual machine at address X'181' and
mount the Natural installation tape.
Before you can start the Natural INPL, the Adabas environment for your CMS machine must have been set up (as described in the Adabas documentation).
Issue the following CMS command:
NKAINPL
You are prompted for the name of the command to invoke Natural. Enter one of the following:
the name of the Natural module built in the corresponding step, or
the name of the Natural DCSS (Discontiguous Shared Segment) bootstrap created in the corresponding step.
NKAINPL then positions the tape and loads the
Natural for MBCS system objects.
The Natural system file definitions as coded in the Natural parameter module apply.
Three reports are produced on your virtual printer. Check these reports to ensure that no errors have occurred.
Copy the Natural module and the DCSS bootstrap to a public disk or have your system programmer copy them to the CMS Y-disk.
