The Autoinstall Control Program At Install; The Communication Area At Install For Consoles - IBM SC34-6814-04 Customization Manual

v Enable the CICS AUTOINSTALL function for consoles. You can do this either by
v Specify the AIEXIT system initialization parameter to define your autoinstall
If AICONS=YES is specified, or a CEMT (or EXEC CICS) SET AUTOINSTALL
CONSOLES(PROGAUTO) has been issued, CICS invokes your autoinstall control
program when:
v An autoinstall INSTALL request is being processed.
v An autoinstall request has previously been accepted by the autoinstall control
v The delay period since the console was last used has elapsed.

The autoinstall control program at INSTALL

If autoinstall is operative, you can specify that CICS is to invoke the autoinstall
control program for MVS consoles, in addition to those devices listed on page "The
autoinstall control program at INSTALL" on page 517. To enable CICS to invoke the
autoinstall control program for consoles, specify AICONS=YES as a system
initialization parameter, or issue a SET AUTOINSTALL CONSOLES(PROGAUTO)
command.
On each invocation of the autoinstall control program, CICS passes a parameter list
to the control program by means of a communication area addressed by
DFHEICAP. This section describes only the install function of console definitions.
The control program is invoked at INSTALL for a console when:
v CICS has received a MODIFY command from an MVS console whose console
v CICS has completed autoinstall processing to a point where it needs a terminal

The communication area at INSTALL for consoles

The layout of the communication area is shown in Figure 44 on page 537.

1. You can have only one active autoinstall control program to handle
terminals, consoles, and APPC connections. You specify the name of
the active program on the AIEXIT system initialization parameter.
