title: ORA-01654: unable to extend index
body: <p>Calling all Oracle Gurus!</p>
  
  <p>I am in the process of clustering a well tested application on WebSphere. The application in question made it about half way through processing 1k of JMS messages from a queue before this happened.</p>
  
  <pre><code>---- Begin backtrace for Nested Throwables
  java.sql.SQLException: ORA-01654: unable to extend index DABUAT.INDEX1 by 128 in tablespace DABUAT_TBLSP
  
      at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

      at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:745)
  </code></pre>
  
  <p>I have had a quick look online and found a few possible suggestions as to why this could have happend,  if anyone could give a clear explanation as to why this may have occurred now my application has been clusterd I would be most grateful.</p>
