Andy,

OK. But wouldn't it be consistent, then, if the actual table attributes
were also spooled out to the SQLFILE (identical command line arguments
provided)?

I think you misunderstood me. If I do NOT provide any transformation
arguments, then the correct segment creation clause should be in the
SQLFILE. But there is no such clause. IMHO, if the import does create
segments immediately, there should as well be a "segment creation
immediate" clause in the sqlfile. But there isn't.

Have a nice weekend,
Uwe
