Note
Message formats and protocols used between the Freeway server
and its client applications are subject to change in future releases.
If you write applications without DLI or TSI layers, you may not be
able to migrate the applications easily when the message formats
and protocols change. If you write applications that access the TSI
layer directly, use caution in sizing buffers submitted to the TSI;
refer to the “Buffer Management” section in the Freeway Transport
Subsystem Interface Reference Guide.
The Freeway trace feature is a valuable debugging tool for client applications. This facil-
ity captures each packet transferred over the socket interface at the TSI level, the DLI
level, or both levels. See the Freeway Transport Subsystem Interface Reference Guide and
the Freeway User Guide for information on how to configure your client and server for
tracing. An appendix in the Freeway Transport Subsystem Interface Reference Guide
shows an example of trace output.
1.2.1 Defining TSI Configuration
After you install the Freeway software as described in the Freeway User Guide, you must
configure the TSI:
• Use the server TSI configuration file to configure the Freeway server TSI layer. You
must do this regardless of whether or not you use the client TSI layer. The server
TSI configuration file is described in the “Customizing System Configuration”
chapter in the Freeway User Guide.
• If you use the client TSI layer, you must use the client TSI configuration file to
define parameters for the TSI connections between your client application and
Freeway. The client TSI configuration file is described in the “TSI Configuration”
chapter in the Freeway Transport Subsystem Interface Reference Guide
