Laly, Your question dose not match to the problem you had mentioned, Do you really understand that what is cloning of Database, It means exact copy of your production and import is not the part of Cloning senario. Looking at the problem it looks like you do not have RBS tablespace. Nisar Tareen Laly <lspel@xxxxxxxxx> wrote: Hi All i am cloning a productive database in another server. This new database (9i) has problems when i run the import. The import gives errors because i haven't created the rollback segments and the database has the system tablespace as the rollback seg.
