Hi all.

I apologise if it is a duplicate post. I didn't see this message on the list so I'm trying again.

We have a table with initial set to 32K and next set to 1M. This table is being loaded daily via a SQL*Loader in parallel mode (8 way) with direct=true. When I look at this table in the dba_Segments I see that all the new extents are 16K and looks like many of them are empty. I read a few documents regarding sql*loader in parallel direct mode, but I'm still confused as to why are these extents are all 16K instead of being 32K (some) and 1M (most). Also why do I see unused blocks ?

thank you
Gene
