The database returned the following error:

[Oracle] #11 
Database Error State: S1000

There will be an entry in the alert.log with the cause, plus (probably) an associated trace file. Please edit your question with the alert.log entry. –  Phil Sep 20 '12 at 11:29
    
@Naims which is the database version? this looks like a bug. I can make a search if you give me more data. –  Ste May 22 '13 at 11:37
