the situation :
A few days ago I inserted a lot of records (400.000) into my database, since
then I sometimes experience low cpu-power (those moments last around 2
hours) Even when no users are logged into my database.
Is it possible oracle organizes maintenance and takes 30-40% of my cpu ?
(every half hour a small boost in HD-activity)
Before it did not suffer such a loss in cpu-power.
So how can I prevent it ? with some kind of setting ?

tnx in advance
