    HI,

    I have one index in one table. I have allocated initial extent 40MB and next 40MB for the index. It has taken one extent only.

    Any one has any script to know , how much really it has occupied, out of 40 MB of space for index..?

    Try bytes column of DBA_SEGMENTS view for the index segment you are interested in...

    BYTES in DBA_SEGMENT will show the allocated bytes not the actually used.
    use DBMS_SPACE to see the actual space.
