You should have found a CPU time,
and a couple of I/O times (seek and block transfer) in aux_stats$ that get set at database startup. 10g will be using the mechanism, even if there aren't any values for the rest of them - so it's a good idea either to disable the feature, or to set some suitable values.

Hi,

I was reading oracle docs and it mentioned that "system statistics" are enabled by default but when I query aux_stats$ TABLE they are not there and only when I ran dbms_stats.gather_system_stats they are inserted into this table. Do I need to set some parameter to enable these on 10g or they have same behavior as of 9i?

Thanks
