One configuration option the Alarm ODBC Service provides is the update interval. This option controls how often to check for alarms. The service checks for alarms every 1 second by default; however, you can enter any interval from 1 to 300 seconds.
You can also define an optional backup file for the Alarm ODBC Service. The service saves alarms and messages to this file if it cannot access the relational database. The file, ALMODBC.TMP, resides in the Alarm path. When the relational database re-establishes contact with the Alarm ODBC Service, iFIX automatically reads the data in the temporary file to update the relational database.
