This document describes the steps for installing the Natural Optimizer Compiler (product code NOC) on z/OS.
For information on the features and functions provided by the Natural Optimizer Compiler, see the Natural Optimizer Compiler documentation.
When used in this document, the notation
vrs
or
vr
represents the relevant product
version (see also Version in the
Glossary).
See General Prerequisites and System Support in the section Overview of the Installation Process.
The installation medium contains the following data set required for product installation:
Data Set Name | Contents |
---|---|
NOCvrs.LOAD |
Load modules |
Copy the data set into your environment as described in Copying Data Sets to a z/OS Disk in the section Installing Natural.
Sample installation jobs are contained in the NATvrs.JOBS
data set
and are prefixed with the product code. The data set is provided on the
installation medium supplied for base Natural.
Be sure to read Installation Process and Major Natural Features before you start the installation procedure.
In addition to the Natural product license file, a license file is required and must be installed for each environment in which Natural Optimizer Compiler (NOC) runs. For license file NOCvrs.LICS, see Step 2: Prepare, Convert, Assemble and Link the License File.
Natural Optimizer Compiler will not be enabled unless a valid Natural Optimizer license file is installed. Trying to activate the NOC without a valid license file results in warnings or errors at session start.
(Jobs I060 and I080)
Activate the Natural Optimizer Compiler by adding the following macro to your Natural parameter module:
NTOPT 'INDX,OVFLW,ZD=OFF'
See also Macro NTOPT in the Natural Optimizer Compiler documentation.
Assemble and link the Natural parameter module.
(Jobs I060, I080)
Adapt the link steps for Natural:
Add the following INCLUDE
statement to the link of the nucleus to
include the Natural Optimizer Compiler modules:
INCLUDE NOCLIB(NOCNUC)
Add the corresponding DD statement:
//NOCLIB DD DSN=NOCvrs.LOAD,DISP=SHR
Relink your nucleus as described in Link the Nucleus in Installing Natural.
You can verify the successful installation of the Natural Optimizer Compiler by performing the following steps:
Recatalog an existing program or write a new program and then catalog it.
Check the directory information for the program you have just cataloged, by using the
following LIST
system command:
LIST DIR object-name
The directory information for the specified object will be displayed, showing the size of the machine code at the bottom of the screen.
