thanks - which we could say is brought on by the increase in cpu utilization that has resulted from an increase in executions of all sql's due to the increased number of users (user count increased by about 400 during this interval)? Utilization is seen about 75% peak at 100% (for short intervals). ________________________________ From: Vladimir Andreev <vandreev@xxxxxxxxx> To: oracledbawannabe@xxxxxxxxx Cc: Oracle-L@xxxxxxxxxxxxx Sent: Thu, November 25, 2010 4:27:02 PM Subject: Re: CPU Per Exec - SQL Ordered By CPU Time I'm wondering what would cause the CPU per Exec to be greater during the Peak time? Latch spinning might explain (part of) the difference. Flado
