I am running my oracle on a debian machine. Today I decided to create a new user and a new tablespace. Then I export a database with the user System which on the same machine. I got some error when I try to import to my new user account.
here is what I've done:

```
./imp mynewuser/passwrdb@orcl file=newdump_sept.dmp system/tomynewuser

Import: Release 10.2.0.1.0 - Production on Thu Sep 29 18:06:23 2011

Export file created by EXPORT:V10.02.01 via conventional path

```

Any suggestion to my problem?
