title: Oracle dba_data_files table doesn't exist
body: <p>I've been trying to access the <a href="http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/statviews_3083.htm" rel="noreferrer">dba_data_files table</a> to see whether the <code>autoextend</code> is turned on for my data files.  However, even though I'm using Oracle 10g, this table seems to not exist:</p>
  
  <pre><code>Connected to:
  Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
  With the Partitioning, OLAP and Data Mining options
  
  SQL&gt; select * from dba_data_files;
  select * from dba_data_files
                *
  ERROR at line 1:
  ORA-00942: table or view does not exist
  </code></pre>
  
  <p>Is there some other way to check and even change whether a data file for a particular tablespace has the autoextend option turned on?</p>
