Description Peter Vogler 2011-09-29 06:54:26 UTC 
When you want to delete a page in an Mediawiki running on Oracle, you get the following error:
1407: ORA-01407: cannot update ("SCHEMANAME"."RECENTCHANGES"."RC_CUR_ID") to NULL“. 

So therefore I checked the database schema for Oracle and found out, that e.g. the RC_CUR_ID column is not allowed to NULL, but upon on delete of the foreign key data, it should be set to NULL.

I found this definition for the following tables:
- archive
- filearchive
- image
- ipblocks
- logging
- oldimgae
- recentchanges

In the Postgre schmema I saw that these columns are allowed to be NULL.

Maybe th columns for Oracle could be changed that way, or they will be set to the a default on delete?

Considering the scope of this request, I think Jure Kajzer would be able to help out with the above stated issue.
Hence, assigning this bug to Jure.
