We have made a course backup on a 1.7.1-mysql-windows-system and uploaded the zip file to our new 1.7.1-oracle-solaris-system!

We started the restore process and got some ora errors (take a look at the screenshot)

The process doesn't stop and in the end finishes successfully...
the problem seems to be, that the system doesn't find the standard scale (with the below sql statement), which is then duplicated in all of our courses (in /course/scales.php?id=x)
Now we have more than one identical standard scale (with the german description: Durchaus differenziertes Wissen,Durchaus differenziert und fundiert,Zeigt ziemlich fundiertes Wissen) and can't delete them at /course/scales.php?id=x, because of the "2" under activties...so there is no delete button...

Here is some better readable error message:

1. Creating scales
   ORA-00932: nicht übereinstimmende Datentypen

SELECT * FROM m_scale WHERE scale = 'Durchaus differenziertes Wissen,Durchaus differenziert und fundiert,Zeigt ziemlich fundiertes Wissen' AND courseid = '0'
