I agree with Lex... i.e. you should use SQL tracing, this is the simpler = way.=20 Other possibilities: - use flashback version query pseudocolumns to extract the timestamp of = last modification for each table (only available in 10g)=20 - give a look to the redo logs with the logminer or, if you are in 10g, = with flashback_transaction_query.
