title: unable to update a table for some times
body: <p>I am facing a strange behaviour in my oracle 10g DB.  Frequently I am unable to update one of my table via sql developer. When I fire "Update" Query more than 1000 Secs the query still running. The content of that table is very very less.</p>
  
  <p>How can I resolve the above issue? Is there any methods.</p>
  
  <p>Regards,
  Jerald.</p>
