Natural selectable units provide the option to use selective new or changed Natural features as required instead of completely upgrading to a new Natural version.
Selectable units are implemented as
NATSUPvr
module (depending on the
Natural version installed) which is loaded on request during Natural session
start. However, if you want to use selectable units under CICS TS, you need to
perform the optional installation step described in Selectable Units
Module in Installing Natural CICS
Interface on z/OS in the Installation
documentation.
To select and activate or deactivate selectable units
Set the SELUNIT
profile
parameter as described in the Parameter Reference
documentation.
To list all available selectable units and their operational status
Issue the SHOWSU
system
command described in the System Commands
documentation.
The SHOWSU - Selectable
Units screen appears with a list of all selectable units
available in your environment and indicates their current status (available
and/or active) as specified with the SELUNIT
profile
parameter.
To list active selectable units only
If you only want to list all selectable units that are currently
active in your environment, issue the SYSPROD
system command (see the System Commands documentation).
On the Installed Products screen, enter the line
command SU
in the Product Name column next to
Natural
.
If a selectable unit is active in your environment, a window opens
indicating the number of the unit and the Natural feature supported by this
unit. Otherwise, the window shows the message No unit
activated
.
If you enter the command SU
for a
Product Name that does not support Natural selectable
units, a corresponding message appears.
