You need the timing from the Query Coordinator process. It will include the time of the Parallel operation(s).

Subject: Caclutating execution time
Hi ,
I had one query which ran in parallel. Now i want to know it's total execution time but from last snap 7621 which says it ran for 126 hrs but i actually hadn't took that much. So, how to calculate real elapsed time.
Oracle 10.2.0.3
select snap_id ,px_servers_execs_total,
elapsed_time_delta,elapsed_time_total,rows_processed_delta,rows_processe
d_total from dba_hist_sqlstat where sql_id='xxxxxxx' order by snap_id
SNAP_ID PX_SERVERS_EXECS_TOTAL ELAPSED_TIME_DELTA ELAPSED_TIME_TOTAL ROWS_PROCESSED_DELTA ROWS_PROCESSED_TOTAL
