title: Issue with materialized view refresh
body: <p>We have two databases, one on 11g and the other on 10g. On 11g we have a few tables the data of which are copied over to 10g using materialized views and database links. So in short</p>
  
  <p>Master table on 11g<br/>
  Materialized view on 10g<br/>
  Db link on 10g</p>
  
  <p>The problem we are facing is that the materialized view refresh is not always working. MV refresh is not giving any errors. Its just that any change in data in the master table is not reflecting on the materialized view after refresh.</p>
