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 NATv, where
v is the first digit of the current
Natural version.
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.
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 that 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.
