title: NLS_NUMERIC_CHARACTERS setting for decimal
body: <p>I have one db setup in a test machine and second in production machine. When I run:</p>
  
  <pre><code>select to_number('100,12') from dual 
  </code></pre>
  
  <p>Then it gives error in test machine. However, this statement works quite fine in production machine.</p>
  
  <p>Now, when I check for NLS_NUMERIC_CHARACTERS then I see ',' (comma) in both machine. Is there anywhere else I should be looking for the decimal setting?</p>
  
  <p>Cheers!</p>
