5.10 Configuring the APPX/TCP Drivers
MAINCON Configuration Panel: E5: “APPX/TCP”
MAINCON Configuration Panel: E6: “APPX/TCP - cfPPP”
MAINCON must be used to define at least one configuration record for APPX/TCP drivers to use. Each
configuration record is used for one host connection and specifies various data about each connection. This is
essentially identical in function to CPI-C (LU6.2) “Side Information”.
For the APPX/TCP drivers essentially all of the data in the configuration record can be overriden with the
APPX Connect-Info function. As with the LU6.2 drivers, if no Connect-Info call is made in the APPX
application, or the Connect-Info call does not specify a record key, the default record (as defined in MAINCON)
will be used. Any other fields specified in the Connect-Info call will override the corresponding MAINCON
definitions. If no Connect-Info call is made, the default record is used, and the only override is the standard
APPX transaction name specification.
MAINCON Parameters
Host Name The DNS name or IP address of the host. For example,
“cf370.cfs.com” or “193.1.1.201” or “193.1.1.201”
NOTE
: the current versions of the cfPPP drivers do not support name
resolution and explicit host addresses must be used.
Port Number The TCP port to which the APPX/TCP session will connect on the
host. For CICS Listener host applications, this should be to port
number specified when the Listener is brought up with “CSKE”
PGM The host transaction program to run -- not used for APPX application
as APPX requires that the transaction program name be specified on
the APPX Connect or Connect-Info call
NOTE:
the transaction program name is case sensitive.
Connect Option The type of connect process required by the host application:
1 - Basic TCP (none)
2 - CICS Listener compatible
3 - Format-3 Connect
Connect Data Optional data sent during the connect process. Usage is dependent on
the Connect Option selected:
Connect Option 1 - Basic TCP (none):
Connect Data is ignored
Connect Option 2 - CICS Listener compatible:
Connect Data is sent as the optional “Client-in-Data” as
described in “IBM TCP/IP for MVS - CICS TCP/IP Socket
Interface, Guide and Reference”, SC31-7131, or in the
Across
the Boards
APPX Documentation.
See “New Features and
Updates for APPX”, Section 16, “Configuring the
cfSOFTWARE CICS Listener for TCP/IP for VSE
.”
Connect Option 3 - Format-3 Connect:
The connect data provides “overrides” which are passed to an
APPX Router to modify the host connection it will establish.
