No, it is not even so. Very probably *all* of your insert batches are fully logged. Inserts are not logged only in some very specific cases, basicaly when you use SQL*LOader's direct path option and when you implement "direct-load inserts". I suggest you take a look at Oracle Concepts manual, where (almost) the whole chapter is devoted to direct-load inserts.

Suppose, I am populating the table every 2 hours, and the operation takes around 1 hour. Does it mean that only the first inserts are not logged but all the subsequent inserts from hour 2, 4 6 etc are logged?
