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 in The autoinstall control program at INSTALL. 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 information describes only the installation function of console definitions.

The control program is invoked at INSTALL for a console when:
  • CICS has received a MODIFY command from an MVS console whose console name is not defined to CICS.
  • CICS has completed autoinstall processing to a point where it needs a terminal identifier and autoinstall model name, from the autoinstall control program, in order to process the CICS transaction passed on the MVS modify command.
