Autoinstalling model terminal definitions

If you define a model terminal for autoinstall, you install it just as you would an ordinary resource definition; that is, by installing the group containing it. However, terminal definitions specified as AUTINSTMODEL(ONLY) are stored only in the autoinstall model table (AMT) at this time; they do not result in a TCTTE on the active CICS® system. These model terminal definitions are stored in the AMT until needed by CICS to create a definition for an actual terminal logging on through VTAM® using autoinstall. The resulting terminal definition is “automatically installed” at this time.

This is what happens when you install a TERMINAL definition, either at system initialization or using INSTALL:

AUTINSTMODEL(NO)
A TCT entry is created for the terminal.
AUTINSTMODEL(YES)
A TCT entry is created for the terminal, and the model definition is stored for later use by the autoinstall process.
AUTINSTMODEL(ONLY)
The model definition is stored for later use by the autoinstall process.

If you install two model TERMINAL definitions with the same AUTINSTNAME, the second one replaces the first.
