Start the data-server translator using:
-<pre> settrans -ac /tmp/trans data-server </pre>
+ settrans -ac /tmp/trans data-server

+You can check if it is running using
-<pre> ps -x | grep data-server </pre>

Run the data-user executable to get the resultant output.
You can remove the translator using:

+ settrans -fg /tmp/trans
To remove the built files use:
