I'm testing profile to limit end users doing ad-hoc queries.

I have a query that is taking 51740 cpu unit according to v$sesstat. In the doc, the unit is "Amount of CPU time (in 10s of milliseconds)" so its 517 seconds.

I've created a profile with cpu_per_call limit of 3000, the unit is in hundredths of seconds, so 30 seconds.

Once the profile created the query fails and when I checked the cpu in v$sesstat it went from 10692 to 21547 so 10855 so 108 seconds.
It should have been around 30 seconds, no ?
