So let me give you a small hint. "count(trunc(FIRST_TIME)) Total" can be also "COUNT(*) Total" which is less CPU consumable then your version. Regards, Damir Vadas Francisco,

“count(trunc(FIRST_TIME)) Total”
can be also
“COUNT(*) Total”
which is less CPU consumable then your version.

However - if the need is to find SQLs that are generating high redo - how will we find that. I know we can use v$session's sql_id column to find which sql - the session is running, but the v$sesstat will not maintain the redo for sql. Any idea how to find that?
