Hi Mayuresh,

derby.drda.traceFile should be passed to the network server process,
but I'm not sure whether testSpecialProps does that. By the way, I
don't think there is a derby.drda.traceFile property, but there is a

What I usually do when I need server-side tracing of a test, is
starting the network server with the required parameters before
running the test. Since a server is already running, the test harness
won't start a new one.

To enable client-side tracing, you need to modify the connection
URL. For parameterMapping.java, I think you can do that by adding
"ij.database=jdbc:derby:wombat;create=true;traceFile=trace.out" to
