Just thoughs:
Thinking outside the box, you could set any string-value as client-ID: it does not have to be the current user. For instance you could make a very elaborate unit test in which you also include the database performance (and suppose this is usefull…). Then, you could set the name of the unit test, or create a logical name for each unit test, and use this name as client-ID. When tkprof’ing the tracefiles you obtain performance characteristics per unit test.

Yes you can. I’m not too familiar with hibernate or toplink, so I can’t point you to the exact classes/methods, but I’m told both frameworks do have classes and methods which are invoked each time a database transaction is started. This is where you invoke the forementioned prepared statement.

In addition, you could create a class that invokes the prepared statement to set the client-ID an inject this into you’re application using AOP.

Is it possible to do the same thing without using ADF BC, i.e, with EJB/Toplink? What class do i have to extend to implement the prepareSession method?
