title: Oracle 10 g - Unable to free up space in tablespace
body: <p>The tablespace in Oracle 10g is almost 100% used. </p>
  
  <p>Size (MB) = 571,768.0<br>
  Used (MB) = 571,534.0</p>
  
  <p>I just deleted (and committed) thousands of records in a table that belongs to a schema associated with that tablespace. Surprisingly, no space was freed up according to the Tablespaces page on Enterprise Manager.</p>
  
  <p>Question: is there anything that I need to do to force Oracle to release the space corresponding to the deleted records?</p>
