    Hie,
    I've a script which give you the growth of your DB during months.

    ------------------------------------------------------------------


    set pagesize 50000
    tti "Database growth per month for last year"

    select to_char(creation_time, 'RRRR Month') "Month",
    sum(bytes)/1024/1024 "Growth in Meg"
    from sys.v_$datafile
    where creation_time > SYSDATE-365
    group by to_char(creation_time, 'RRRR Month')
    /

    tti off

    ------------------------------------------------------------------

    Have fun !!!

    Hello,

    You can also obtain the free and used space through the system views : dba_free_space and dba_segments
    (select sum(bytes)/1024/1024 SIZE_Mo from sys.view_name)

    Best regards

    Hello,

    If you database was created in june 2001, using the script proposed by PWC will give you the size of you database.

    Suppose that you database was created in march 2001 and you added a file of 500 Mo in june 2001, using the script given, you result will be 500 Mo (growth : year - 1).

    Hope this help
