Find start and end execution time of a sql statement?

Find start and end execution time of a sql statement? I am have databases with 10.2.0.3 and 9.2.0.8 on HP UNIX 11i and Windows 200x.

I am not in a position to turn on sql tracing in production environment. Yet, I want to find when a sql statement started executing and when it ended. When I look at v$sql, it has information such FIRST_LOAD_TIME, LAST_LOAD_TIME etc. No where it has information last time statement began execution and when it ended execution.. It shows no of executions, elapsed time etc, but they are cumulative. Is there a way to find individual times (time information each time a sql statement was executed. – its start time, its end time ….)? If I were to write my own program how will I do it?

Along the same line, when an AWR snapshot is shown, does it only include statements executed during that snapshot or it can have statements from the past if they have not been flushed from shared memory. If it only has statements executed in the snapshot period, how does it know when statement began execution? Received on Tue May 27 2008 - 21:58:28 CDT
