Hi, I set up a job to capture the contents of v$sql_monitor once a minute during my ETL run last night. I am having a hard time writing a query to find evidence of queries downgraded to serial. My other queries indicate that there were operations downgraded, but I cannot find them in my version of V$sql_monitor. All the px_servers_requested contents have the same value in px_server_allocated. Thanks for your time, Josh C. -- //www.freelists.org/webpage/oracle-l
