Have you considered using statspack? You can adjust it's frequency and the thresholds it uses for capturing the top SQL. It won't give you exact stop and start times for multiple executions (it might give you the first & last_load_time though), but it will give you a general idea of what queries were running when and their elapsed_time along with their disk_reads, buffer_gets, rows_processed and other stats. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of cosmin ioan Sent: Saturday, October 28, 2006 8:06 AM To: oracle-l@xxxxxxxxxxxxx Subject: re: capturing sql text & times of (long running) queries through trigger?
