Everytime I find a session that has that corresponding sql_id, the session is inactive and shows the last activity was at 1 minutes past the hour. (that is based off of last_call_et)

The few sessions that I found to be using that sql and be active, I turned on tracing but they weren't executing the sql at an alarming rate ( maybe 10 to 20 times in 10 minutes ) which is normal. Is there a bug with AWR reporting that makes it appear that the sql is being executed every centi-second? Received on Wed Jan 09 2008 - 08:21:37 CST
