Gateway Configuration File

Workstation Configuration

2–6

110838 Tandem Computers Incorporated

Default

The default value is 500. Each cache entry requires about 140 bytes of memory.

Example

ElementCacheEntries=123

Try starting with zero and check out your client application’s performance—
other workstation disk caches (such as the Windows SMARTDRV program)
might provide adequate performance by themselves. Then, as necessary,
increase ElementCacheEntries.

ServiceMapFile

This configuration section entry is used to specify the location of the workstation file
where you configure ServiceName objects. These objects are the transaction types that
you can use in your client application (such as “read an employee record”).

Default

If the ServiceMapFile option is not specified, then the Tandem DDE Gateway
looks for a SERVICE.INI file in the current directory in effect when you started the
Tandem DDE Gateway. If a SERVICE.INI file is not found, the Tandem DDE
Gateway will not start.

If you specify just a file name and extension (no directory), then the following
search path will be used:

1.

The current directory in effect when you started the Tandem DDE Gateway.

2.

The Windows directory (the one containing WIN.COM).

3.

The Windows system directory (the one containing GDI.EXE).

4.

The directory containing the executable file for the Tandem DDE Gateway
(TDMGW.EXE).

5.

The directories listed in the DOS PATH environment variable.

Examples

ServiceMapFile=TRANSACT.DEF

ServiceMapFile=C:\TDMGW\TRANSDEF.INI

ServiceMapSection

This configuration section entry is used to specify a specific section within the file
where you configure ServiceName objects (the SERVICE.INI file).

Enter the section name to be accessed within the file you specified using the
ServiceMapFile option described above. You can enter up to 30 alphanumeric and
hyphen characters starting with a letter for this configuration option. Do not enter
square brackets around the section name.
