How CICS builds the list of autoinstall models
CICS builds the list of autoinstall models by selecting from its complete list of
terminal models those models that define console devices. The complete list of
autoinstall models available to CICS at any time comprises all the definitions with
AUTINSTMODEL(YES) and AUTINSTMODEL(ONLY) that are installed, and which
reference a TYPETERM definition that specifies DEVICE(CONSOLE). If CICS
cannot find a model for consoles, it issues message DFHZC6902. If the return code
in the area addressed by fullword 4 of the parameter list is nonzero, CICS issues
error message DFHZC6987. You can obtain a list of autoinstall model definitions
using the CEMT (or EXEC CICS) INQUIRE AUTINSTMODEL command.
Returning information to CICS
At the INSTALL event, the autoinstall control program is responsible for allowing or
denying the installation of a new console resource in the CICS region. This decision
can be based on a number of installation-dependent factors, such as security, or
the total number of connected terminals. CICS takes no part in any such checking.
You decide whether any such checking takes place, and how it is done.
