The installation is performed by installation jobs that contain the JCL required to identify the job to the operating system and run the job.
There are two methods for creating and running the installation jobs:
using the jobs generated by System Maintenance Aid (SMA), or
using the jobs created from the sample installation jobs provided.
The Installation for z/OS documentation solely describes the installation procedure for the jobs generated by SMA. If you do not use SMA for installation, refer to the example installation jobs supplied on the installation medium.
SMA is supplied with base Natural.
For each step of the installation procedure, System Maintenance Aid (SMA) generates an installation job according to your specifications in SMA. You then submit and run the generated job.
Before you can start generating the jobs, you have to load the SMT111.TABS data set from the installation medium into the SMA
system file. SMT111.TABS contains the tables
SMA requires to build the jobs.
SMA is supplied with base Natural. For instructions on loading the data set and using SMA, refer to the System Maintenance Aid documentation.
For installation guidance and information on new or changed SMA parameters and Natural features, you can view the product-specific Readme files by using the appropriate SMA function.
To view a product-specific Readme
From the product list on an SMA Maintenance screen, execute
the RM (Show Readme File) command
for the required product(s).
The sample installation jobs that can be used as an alternative to SMA are provided in a
PDS library contained on the data set
product-code-vrs.JOBS (for example, NAT828.JOBS) shipped on the installation medium.
All sample installation jobs provided are listed and described in the README document that
accompanies the shipment.
You need to adapt the sample installation jobs to your requirements.
Each installation job indicates the product
code and version (for example, NAT828) of the corresponding product (for example, Natural).
Each step of the installation procedure is identified by a job name (for example,
I050) and one or more steps (for example, Steps 0100 and
0101 for Job I050) that indicate the tasks performed by the
job. The job name can have a prefix such as a product code (for example,
NATI050). The prefix can be specified with the SMA parameter
JOB-PREFIX (the default prefix is SMA).
A sample installation job from the PDS library can also have a suffix letter which
indicates a variant of the job. For example: Job I060L is a variant of Job
I060 and used if support of the IBM Language Environment (LE) is required.
In SMA, the same variant is executed with Job I060 and the appropriate SMA
parameter setting.
The installation process comprises the following:
Creating the Natural system files.
Creating the Natural parameter module.
Creating the Natural nucleus.
Loading the Natural objects.
Installing the optional Natural components.
Installing the Natural add-on products.
The installation instructions frequently refer to the Natural INPL utility which is used
to load the data sets (for example, NATvrs.INPL)
contained on the Natural installation medium into the Natural system files. The INPL utility is
invoked with the Natural system command INPL. For detailed
information on the INPL utility, refer to the
Utilities documentation.
After the successful completion of the installation, you can verify the result by starting Natural and testing the system functions as described in the relevant sections of the Installation Verification documentation.
Note
If Natural Security is installed, certain Natural functions and libraries can be
restricted to specific users.
