This is a cut from asktom.oracle.com


  1. Can you elaborate on 'right-hand index problem'? What is it? How to detect it and how to avoid it?

Tom wrote
1) it is a rare issue in very high end systems. It is inserting into a table that has an index on a column that is always increasing (eg: a column populated by a sequence). All of the values goto the "right hand side".
reverse key indexes may be useful in such a case. It is *very rare* to need to go that far.
