title: Alter Segment created
body: <p>I'm doing:</p>
  
  <pre><code>ALTER TABLE WG106_STAGE ALLOCATE EXTENT;
  </code></pre>
  
  <p>to change <a href="https://i.stack.imgur.com/nceKO.png" rel="nofollow noreferrer">Segment created yes</a> to <code>YES</code> from <code>NO</code>.</p>
  
  <p>The value is changed, but after some time it's back to <a href="https://i.stack.imgur.com/Z6wGh.png" rel="nofollow noreferrer">Segment created no</a> </p>
  
  <p>It is not an fix operation?</p>
  
  <p>I'm running on that table an <code>INSERT</code> or <code>UPDATE</code> and after that <code>TRUNCATE table WG106_STAGE drop all storage</code> every 10 minutes.</p>
