Re: Query execution time

 Apart from tracing (which with such a rate of execution is not highly advisable) the best you can do is probably collect those aggregate values at regular intervals, compute differences and work out averages on a per interval basis. You will still have a smoothed curve, but less so. If you have a single statement to monitor and use the V$SQL ADDR as key, you can probably do it at a resonably high rate. Regards,

I have a query that has been executed 750,000 times and want to know what the maximum elapsed time is for that query. The v$sql view gives me an elapsed_time column, but that will only allow me to produce an average elapsed time based on the number of times a query has been executed. Is there a way to determine the maximum elapsed time for a query?

Thanks,

Rick Stephenson
