or you can drop specific users and all it's objects using:

DROP USER CASCADE

This is a vary bad idea. There are a number of schemas besides SYS and SYSTEM that need to be intact to have a usable database. It takes about 30 seconds to make a new blank database, much faster then dropping everything. Remove the database, rebuild it and reload your export.

Ok, sorry about that :oops: . I used to use this to wipe a database before reloading a backup. I’ve changed it so your no longer logging in as sys. I think the original way probably wiped out your data dictionary, Doh!

Just a warning: On Oracle 10g this made my database completely unusable. I couldn’t even login using SYSDBA. I could stop it but not start it again.

It didn’t matter too much because it was a development database that I wanted to drop the data from, but it did put the database in such a state that I couldn’t reload a new file into it using imp.

Instead I’ve had to use the Database Configuration Assistant to create a new blank database again.
