The beauty is that it is database independent, so I can apply the same technique whether the customer is using Sybase, DB2, Oracle, MySQL, etc. Once we have discovered that the database is indeed a bottleneck, we would pass that information to someone like you who can then run a detailed trace. Thanks for the link for Oracle though :-) With P6Spy, you have a JDBC driver that logs the times automatically.

Rather than manually logging the times, it would be more convienient - and helpful for the 'expert' - to generate a database level trace. Here is how to do that: http://repettas.wordpress.com/2008/09/19/oracle-10046-trace-for-new-users/ @Kabutz, yes please feel free.

DB Performance is still a bit of a mystery to me. I usually log the times that each query takes and if they are long, then I'll point them to an expert like yourself. At least I will know who to ask for advice next time I write a horribly slow DB query :-))) Heinz Nice talk. DB Performance is still a bit of a mystery to me.
