Ayyappan - What I have found useful for estimating Index size is to analyze
the index and use the LEAF_BLOCKS column in USE_INDEXES. This is usually
close enough for estimation purposes, and it is easy to join with other
tables.
Another thought, you may want to run Don Burleson's script,
http://www.dba-oracle.com/art_index1.htm, and rebuild any indexes it
suggests. Some of these indexes may be taking up too many blocks, and that
will throw off your estimates.
