Synclevel 1 connections installed via a BIND

Synclevel 1-only APPC connections autoinstalled via a BIND request (except for
limited resource connections installed on a CICS generic resource member—see
next section) are implicitly deleted at the following times:
vWhen the connection is released
vIf VTAM abends
vWhen the VTAMACB is closed by CICS
vAfter the expiry of the AIRDELAYinterval following a warm or emergency start (if
the value of the AIRDELAYsystem initialization parameter is greater than zero).

Synclevel 2 connections installed via a BIND

Synclevel 2-capable APPC connections installed by a BIND request are implicitly
deleted only if they are installed on a CICS generic resource member, and an
affinity is ended. Otherwise, they are never implicitly deleted.
The same applies to synclevel 1-only, limited resource connections that are installed
on a CICS generic resource member.
The sample autoinstall control program for APPC connections
The sample control program for autoinstall of APPC connections is DFHZATDY. The
source code, in assembler-language only, is in library CICSTS32.CICS.SDFHSAMP.
As well as providing function to autoinstall APPC connections initiated by BIND
requests, DFHZATDYprovides the same function for terminal autoinstall as the
DFHZATDX program described in Chapter10, “Writing a program to control
autoinstall of terminals,” on page 515. Thus, you can use a customized version of
DFHZATDYto autoinstall both terminals and APPC connections.
Default actions of the sample program
The role of DFHZATDYin installing APPC connections is to choose the template to
be used (by supplying its NETNAME or SYSID), and to supply the name (SYSID) of
the new connection.
The actions taken by the supplied version of the program are to:
1. Examine the request type passed in the INSTALL_APPC_EXIT_FUNCTION
field:
X'F0' An incoming CINIT for a terminal or APPC single-session device.
Proceed as for DFHZATDX. See Chapter10, “Writing a program to
control autoinstall of terminals,” on page 515.
X'F1' A delete request for a terminal orAPPC single-session device. Proceed
as for DFHZATDX. See Chapter10, “Writing a program to control
autoinstall of terminals,” on page 515.
INSTALL_APPC_PS_CINIT (X'F2')
An incoming CINIT for an APPC parallel-session connection. Specify a
template by setting the field pointed to by
INSTALL_APPC_TEMPLATE_SYSIDto 'CCPS'.
