export and import

Hi experts

I am working with ArcGIS 10.1, Oracle SDE geodatabase.
I exported (by using XML workspace) set of feature classes from a schema (schema only) succesfully from one instance.
I tried to import these to same schema in another instance, then it is failed with a error:
Import XML failed ....ORA 01031 insufficient privileges.

What kind of privileges are required to improt xml workspace document ??

On the other hand, Can I use Oracle utilities for export and import for geodatabase ??

Regards
