title: Two indexes with same name in Oracle schema
body: <p>I'm wondering why can't I have two indexes with same name in Oracle schema? It throws an error  saying that the name is already been used.
  I was under an impression, since the index is on a particular table, this should not cause any error unless we use same index name for two different columns on the same table.</p>
  
  <p>Any explanation is most helpful.</p>
  
  <p>Thanks in Advance!</p>
