title: Oracle RAC and sequences
body: <p>I have various database applications that use sequences, I´m migrating these applications to Oracle RAC from 10g without RAC to 11g with RAC. I need ordered sequences and gaps are tolerated.</p>
  
  <p>I'm thinking in cache sequences with order, I don´t know what are the effect in performance. Do you think this is a good option? What are your experience with sequences and RAC?</p>
  
  <p>Thanks,</p>
