title: Oracle error messages
body: <p>I'm curious about something... is it possible for an Oracle 11 instance to be configured so that it does not return any ORA-?????? error messages?  </p>
  
  <p>I've issued many invalid queries where I've misspelled column names, table names... things where I would expect an ORA error message.</p>
  
  <p>Say for security purposes say if a stray java stack trace got exposed to a browser could you force oracle to always show the same bogus error message in the stack trace?</p>
  
  <p>I always get this one:<code>java.sql.SQLException: IO Error: Size Data Unit (SDU) mismatch</code></p>
  
  <p>I've googled that error up and down, and I do not have any connection or database configuration issues at all!  I get it on a per-query basis.</p>
