As I mentioned a few weeks ago, IMHO, singling out events to ignore in a system-wide or even session-wide data collection is the wrong thing to do. But you must ignore some events if you first make what I consider to be errors in how you collect your data. If you collect data for only the problem program during only the problem duration, then you should ignore *none* of the events that you see. If you collect the data this way, then *everything* you see will be a component of end-user response time.
Any other data collection method is misleading (and time-wasting) in many cases; one example of such a case is the rather longish example I described.

I am able to determine the service time by the "CPU used by this session" line in the statspack report. The wait time I am having trouble with. I am working from the 'Yet Another Performance Profiling Method' document. The document lists a number of events that should not be included in the calculation because they are caused by background process waits. I am tuning an 8.1.6 databases and want to be sure I am only counting the appropriate events in this calculation. How can I get the list of events to include for my version of the database (the doc is quite old)?
