This document contains an overview of special considerations that apply when you are running Natural under z/OS.
A Natural subsystem under z/OS consists of the following components:
one or more Global Buffer Pools,
a Roll Server.
The Natural subsystem is identified by the Natural profile parameter
SUBSID
and by corresponding startup parameters for the components mentioned above. The
default subsystem name is NAT4
.
Via the Natural subsystem technique, multiple roll servers can be used simultaneously and multiple independent sets of global buffer pools can be created - in fact, multiple Natural runtime environments can be created which will be totally independent of one another.
The advantages of a Natural shared nucleus are explained in the section Natural Shared Nucleus under z/OS and z/VSE.
For information on the TP monitor interfaces that are available with Natural under z/OS, refer to the sections
in the Natural TP Monitor Interfaces documentation.
Except for Software AG's database management system Adabas, all operations requiring database interaction are performed by a corresponding Natural interface module.
For information on the database interfaces thta are available with Natural under z/OS, refer to the relevant separate documentation:
See Natural in Batch Mode (All Environments) and Natural in Batch under z/OS.
Besides being a programming language, Natural can also act as a server in a client/server environment. For detailed information, see Natural as a Server under z/OS.
