Excluding unwanted programs

There are three ways to exclude programs that are not required.

You can exclude programs by specifying:

programname=NO
tablename=NO
function=NO

Specifying programname=NO
If you code system initialization parameter programname=NO (for example, DIP=NO), you exclude the named management program at CICS system initialization.
Specifying tablename=NO for the programs control table
Not all of the CICS programs have a programname parameter in the SIT.
The dummy TCT, DFHTCTDY
There is a special case where you can also specify tablename=NO, but this does not load a dummy terminal control program. You specify TCT=NO when you are using resource definition online, and all your terminal resource definitions are in the CSD.
Specifying function=NO
If you code function=NO as a system initialization parameter, you exclude the management program associated with the named function at CICS system initialization.
