Chapter 11. Writing a program to control autoinstall of
consoles
Considerations common to all user-replaceable programs
Note that the comments contained in “Chapter 5. General notes about
user-replaceable programs” on page 401 apply to this chapter.
This chapter describes how to write a program to control the automatic installation
of MVS console devices (including TSO consoles). For information about controlling
the automatic installation of locally-attached VTAM terminals, see “Chapter 10.
Writing a program to control autoinstall of terminals” on page 485.
The chapter is divided into the following sections:
1. “Preliminary considerations”.
2. “The autoinstall control program at INSTALL” on page 506
3. “The autoinstall control program at DELETE” on page 510
4. “The sample programs and copy books” on page 511
Preliminary considerations
The reasons for using autoinstall for MVS consoles are the same as those that
apply to the autoinstall for VTAM devices: you don’t have to define each device
explicitly, and you save on storage (see “Preliminary considerations” on page 485).
Leaving it all to CICS
For consoles, in addition to the normal autoinstall support, you can also choose to
let CICS autoinstall consoles without calling the autoinstall program. In this case,
CICS uses either:
v A model console definition with an AUTINSTNAME (model name) that matches
the MVS console name, or
v The first suitable console model it finds in alphanumeric sequence
If the autoinstall control program is not called, CICS generates a 4-character termid
starting with the ¬ (logical not) symbol.
If you want CICS to install your consoles automatically:
v Specify AICONS=AUTO (or issue a CEMT (or EXEC CICS) SET AUTOINSTALL
CONSOLES(FULLAUTO) command).
v Create at least one model TERMINAL definition that references a TYPETERM
definition specifying DEVICE(CONSOLE). You can use the IBM-supplied
definition in group DFHTERMC if it suits your needs.
v Install the model TERMINAL and TYPETERM definition.
