To provide symmetry of control over the autoinstall process,
the autoinstall control program is also invoked when an autoinstalled
APPC connection is deleted.
Invoking the control program at DELETE enables you to
reverse the processes carried out at the INSTALL event. For example,
if the control program at INSTALL incremented a count of the total
number of automatically installed resources, then the control program
at DELETE would decrement that count.
Input to the program is by a communication area, addressed
by DFHEICAP. The layout of the communication area is shown in Figure 1. Figure 1. Autoinstall
control program's communication area at DELETE. For
APPC connections initiated by BIND requests.
Fullword 1 Standard Header
Byte 1 Function Code (X'F5' or X'F6')
Bytes 2 - 3 Component Code Always "ZC"
Byte 4 Reserved Always X'00'
Fullword 2 SYSID of deleted connection
Fullword 3 NETNAME of deleted connection
Bytes 1-2 NETNAME length
Bytes 3-10 NETNAME
The Function Code byte (byte 1 of fullword 1) indicates
why the user program has been invoked:
X'F5'
After deletion of a parallel-session APPC connection that was
initiated by a BIND.
X'F6'
After deletion of a single-session APPC connection that was initiated
by a BIND.
Note: The value X'F1' represents the deletion of
a local terminal, or an APPC single-session device that was autoinstalled
via a CINIT request. For more information, see The autoinstall control program at DELETE. The value X'FA' or X'FB' represents
the deletion of a shipped terminal or connection. For more information,
see Autoinstall control program at DELETE. The value X'FC' represents
the deletion of a Client virtual terminal. For more information, see The autoinstall control program at DELETE.
