Service Map
Configuration File
For each transaction type you reference in a client application program (such as “read
an employee record”), you must enter a ServiceName object and its associated
attributes into the service map configuration file. The file name and section name into
which you enter ServiceName objects are identified by the ServiceMapFile and
ServiceMapSection options in the [Configuration] section of the Tandem DDE
Gateway configuration file (with the default name of TDMGW.INI).
You reference the ServiceName objects in your client application programs with the
DDE Execute INITIALIZESERVICE command.
By entering a ServiceName object, you associate a transaction type with a Tandem
Pathway server class name or Guardian process name, declare message buffer sizes,
and define a data communications session type over which the transaction is to be
processed. Guardian process names can also include an Expand node name. You can
define up to 1,500 ServiceName objects. If you define many ServiceName objects
(more than 500), you can save a few seconds of Tandem DDE Gateway startup time by
entering the ServiceName objects in ascending order by ServiceName.
You can find the ServiceName object buffer sizes in a number of ways.
Use the Tandem DDE Gateway Browser on your workstation. Click the \X(View
Message) button for any message and the message size will be displayed in the
caption bar of the View Message dialog box. See Section 4, “Creating Client
Applications,” for more information.
Use the Tandem DDE Gateway Dictionary Report output by the Bridge program
on the Tandem system. See Section 5, “The Tandem DDE Gateway Bridge
Program.”
Compile your COBOL servers on the Tandem system with the ?MAP option. The
listing shows the size of all data structures in the program.
