Hi All,

DB Time in all my awr report(during peak hours and non-peak hours) are showing a high value ,which is higher than Elapsed time

See couple of AWR reports of our peak and non-peak hours:

Snap Id Snap Time Sessions Curs/Sess
--------- ------------------- -------- ---------
Begin Snap: 12353 02-Mar-09 08:00:24 769 105.1
End Snap: 12356 02-Mar-09 11:00:51 950 133.0
**Elapsed: 180.45 (mins)**
**DB Time: 1,749.51 (mins)**


Snap Id Snap Time Sessions Curs/Sess
--------- ------------------- -------- ---------
Begin Snap: 12347 02-Mar-09 02:00:45 365 125.7
End Snap: 12348 02-Mar-09 03:00:52 361 126.9
Elapsed: 60.11 (mins)
DB Time: 347.28 (mins)



How DB time higher than Elapsed time.
