Question

I am using Oracle ODAC for EntityFramework. I am trying to develop a sample silverlight application using entityframework. I have add my domainservice through which I am publishing my entities. I am UI’s code behind file. I have written the following code.

var threemonthsold = DateTime.Now.AddMonths(-3);
var query = serverContext.GetSR_MERGED_DATAQuery().Where(t => t.SR_DATE_RECD > threemonthsold);

var regionLoadOp = serverContext.Load(query);
dataGrid.ItemsSource = regionLoadOp.Entities; 

I want to find out what query has been sent to oracle. As the operation is getting timedout the application is crashing. Looks like the query is taking long time. If I can find out the query I can run it directly on oracle and find out how long it is taking there.

Any help much appreciated.

Thanks

You can turn on ODP.NET tracing. See the ODP.NET doc for more details:

1) Close VS
2) In windows registry, change registry value 
    \\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\ODP.NET\4..........\TraceLevel
    to 1
3) Relaunch VS
4) Reproduce the problem
5) Close VS2010
6) Look for the odpnet trace file in the root of C I believe.
7) Undo the registry value (set it back to 0) so you don't impact performance
