ORA-02270 error during import

hi

Error during import: ORA-02270: no matching unique or primary key for this column-list

i am in the process of migrating my oracle databases from dg/ux to solaris8 OS. at the same time, i am taking the opportunity to resize the tables, indexes to cater for growth in the near future.

to do this, i hv created fresh the new database with improved settings
(given the luxury of disk space we hv now), created the tables and indexes
with new sizings, moved the export over to the new machine and reimported it. the export was a full export.

on import, i get the above error which means that it cant create a foreign key constraint becos the primary key constraint for the table has not been created. this is the case for quite a few of the tables but most of the 400 or so tables were fine.

why should this occur and under what circumstances wld this occur? and how do i fix this?

almost all the documentation i hv checked including oracle web sites do not offer a solution and I am not sure the best way forward without a lot of workaround being done which may not be ideal.

wld any Oracle gurus be kind enough offer any ideas or thoughts on this except that the export/import utility is probably buggy.

many thanx
