title: Oracle 10g Table size after deletion of multiple rows
body: <p>As part of maintenance, we remove a considerable amount of records from one table and wish to dispose of this space for other table. The thing is that I'm checking the size of the table and it shows the same original size before the delete. What am I missing here?</p>
  
  <p>To check the size, I'm looking at the <code>dba_segments</code>.</p>
