Hi List,

I am trying to calculate the average database response time for a data
center audit currently underway.  Without "expensive" monitoring tools, is
it possible to determine this from database statistics.  So far, I'm using
(Service Time + Wait Time) / calls where this translates into  

Service Time    = 'CPU used by this session' from v$sysstat
Wait Time       = sum(time_waited) from v$system_event (excluding idle
events)
User calls      = 'user calls' from v$sysstat

Am I way off the mark here?

Interestingly, it seems as if Craig Shallahamer (www.orapub.com) is
preparing a paper which addresses this very issue - determing response time
from database statistics - but it is only due out later this year.

Anybody with any ideas or reasons why the above is not feasible?

TIA
Paul
