Hello there,

depending on the kind of objects in this export file i would guess that there are a lot of stored procedure in there which are imported first.

I keep an eye on my imports by doing a  

   select owner, count(*)
   from sys.dba_objects
   where owner not in ('SYS','SYSTEM')

during the import.

I have one owner that has about 5000 stored procedures in his shema and only a few other database objects.
It takes more than an hour until the import shows any imported rows ...

Bye,

Andreas
