You control autoinstall by means of an autoinstall control program, either user-written or supplied by CICS®. This program is responsible for, among other things, providing the model name or names to CICS, providing VTAM® information to CICS for autoinstall for terminals, and so on.
CICS provides three autoinstall control programs; one for terminals; one for both terminals and connections; and one for programs, map sets, and partition sets. You can use the CICS-supplied ones or you can customize them to suit your installation.
