D-10 Customizing the DecisioNet System
External Data Interface (with AMS)
When the optional EPL Information Messaging System package is
installed, the External Data Interface starts with the other EPL
applications. The External Data Interface audits price changes from the
scheduler and ensures that the SmarTalkers accurately display
promotions by comparing the promotion information in the EPL Item
table against the promotion information defined by the IDX (item type)
in the AMS configuration file (default file name = AMSCFG.TXT) and
user data provided by the PLU reader. The esextdi process also looks
for EDIMOD files to process and applies the PROMO data contained in
these files to the appropriate SmarTalkers by PLU number, price level,
and location.
In a default system, EDIMOD files are looked for every five minutes
(-s300). To change the timing, edit the start scripts and change the
esextdi sleep time option (-s<seconds>) to meet your requirements.
Changing the External Data Interface Time Interval
The default time is 300 seconds (5 minutes) in the S55extdi.bat file
in the Windows NT \epl\bin\scripts directory. Edit the batch file
using the –s option to set the time frame to the desired length.
@echo off
echo Starting EPL External Data Interface Application
if "%1" == "startservice" goto startservice
start /min ..\esextdi
goto finish
:startservice
..\startsrv svextdi
:finish
The default time is 300 seconds (5 minutes) in the S55extdi script in
the UNIX /epl/bin/scripts directory. Edit the batch file using the –s
option to set the time frame to the desired length.
