why we need redo while performing import or export info?
and how we specify version clause if we want to export from 10g to 9g.
Thanks in advance.
You cannot import 10g database dump file to 9i. Because 10 g comes up witg data pump concept. So 9i never accepts data pump file.but reverse is possible. you can import 9i file to 10 g database.. because still 10g has 9i features....
