The autoinstall control program can be started when a console
autoinstall request fails or when the delete delay period has expired.
To provide symmetry of control over the autoinstall process,
the autoinstall control program is also started whenthe following
situations occur:
A console autoinstall request was accepted by the user program,
but the INSTALL process failed.
The delete delay period has passed since the console was last
used and CICS® is running with AICONS=YES in effect. You
can query this status of autoinstall for consoles by using the CICS Explorer®Regions operations
view or by issuing a CEMT INQUIRE AUTOINSTALL command.
If AICONS=YES is specified, the value of the CONSOLES option is PROGAUTO.
Input to the program is through a communication area,
addressed by DFHEICAP. The layout of the communication area is shown
in the following figure: Figure 1. Autoinstall control
program communication area at DELETE for consoles
Fullword 1 Standard Header
Byte 1 Function Code (X'FE')
Bytes 2 - 3 Component Code Always 'ZC'
Byte 4 Reserved Always X'00'
Fullword 2 Terminal ID of console being deleted
Fullword 3 Consolename of console being deleted
Bytes 1-2 Deleted consolename length
Bytes 3-4 Start of deleted consolename ID
Next 6 bytes Remainder of deleted consolename ID
The parameter list contains the following information:
A standard header, where byte 1 indicates the request type (the
hexadecimal character X'FE' represents DELETE), and bytes 2 - 3 contain
the component code, which is always ZC for consoles.
The second fullword contains the terminal ID of the console that
is being deleted.
The third fullword contains, in the first 2 bytes, the length
of the deleted console name and, in the last 2 bytes, the first and
second characters of the console name.
The last 6 bytes of the communications area contain the remainder
of the console name (third to eighth characters).
