DB growth!

Question

Do anyone has a script to find out the different tablespace growth PER DAY.?

Answer 1

hi,
I have used the following but on a monthly basis, It is quite easy to change for a daily growth thogu
Can produce a growth report quite easily
Run following create table to create segment info.
create table stats$segment_info as
select
sysdate snap_time,owner, segment_name,segment_type
, tablespace_name,sum(bytes) bytes
from dba_segments group by owner,segment_type,
segment_name,tablespace_name
-- Run following once a calendar month via dba_jobs.
insert into stats$segment_info
select
sysdate snap_time,owner, segment_name,segment_type
, tablespace_name,sum(bytes) bytes
from dba_segments group by owner,segment_type,
segment_name,tablespace_name
commit;
-- run following report to get tablesapace growth
column this_mon new_value this_mon
column last_mon new_value last_mon
column prev_mon new_value prev_mon
select to_char(sysdate,'MON YYYY') This_mon
, To_char(add_months(sysdate,-1),'MON YYYY') Last_mon
, to_char(add_months(sysdate,-2),'MON YYYY') prev_mon
from dual;
column mins format 99999
column size_mb heading '&&this_mon' format 99999
column size_mb2 heading '&&prev_mon' format 99999
column size_mb1 heading '&&last_mon' format 99999
column growth heading 'Growth(%)| in |last month' format 9999.99
select tablespace_name,
-- to_char(snap_time,'MON YYYY') Month
max(decode(trunc(snap_time,'MON'),trunc(add_months(sysdate,-2),'MON'),size_m,0)) size_mb2
,max(decode(trunc(snap_time,'MON'),trunc(add_months(sysdate,-1),'MON'),size_m,0)) size_mb1
,max(decode(trunc(snap_time,'MON'),trunc(sysdate,'MON'),size_m,0)) size_mb
,100*(max(decode(trunc(snap_time,'MON'),trunc(sysdate,'MON'),size_m,0))
- max(decode(trunc(snap_time,'MON'),trunc(add_months(sysdate,-1),'MON'),size_m,0)))
/max(decode(trunc(snap_time,'MON'),trunc(add_months(sysdate,-1),'MON'),size_m,1)) growth
from
(select tablespace_name, snap_time
,sum(bytes)/1024/1024 size_M
from stats$segment_info
where snap_time > trunc(add_months(sysdate,-2),'MON')-2
group by tablespace_name,snap_time) a
group by tablespace_name
order by tablespace_name
