No, it's not. Other people seem to be able to build expst in Oracle 9.2.0. I'm not. So I wonder if I'm doing something wrong. Or rather: I wonder what am I doing wrong.

Understood. Is that important for the question that I asked?

Understood. But I didn't ask Oracle, did I? :) At least I did not ask them on an "official channel", so to speak.

Any, that doesn't answer the question, does it? :) Would it be possible to build expst on Should it possible to build it on

I'm doing that.

I use BUFFER=20m and recordlength=64k.

It allows to recover data, which is stored in the export. That's sufficient.
