In this article, we are going to check oracle database growth per month. Here we have to script one is for complete database growth and another one is to check growth as per tablespace level.
Oracle Database Growth per month script
Using the below query you can find out the per month database growth.
SQL> select to_char(creation_time, 'MM-RRRR') "Month", sum(bytes)/1024/1024/1024 "Growth in GB"
from sys.v_$datafile
group by to_char(creation_time, 'MM-RRRR')
order by to_char(creation_time, 'MM-RRRR');Output:
Ttablespace level growth script
Using the below script you can check database growth on behalf of the tablespaces.
SQL> select b.tsname tablespace_name , MAX(b.used_size_mb) cur_used_size_mb , round(AVG(inc_used_size_mb),2)avg_increas_mb from ( SELECT a.days,a.tsname , used_size_mb , used_size_mb - LAG (used_size_mb,1) OVER ( PARTITION BY a.tsname ORDER BY a.tsname,a.days) inc_used_size_mb from ( SELECT TO_CHAR(sp.begin_interval_time,'MM-DD-YYYY') days ,ts.tsname ,MAX(round((tsu.tablespace_usedsize* dt.block_size )/(1024*1024),2)) used_size_mb from dba_hist_tbspc_space_usage tsu , dba_hist_tablespace_stat ts ,dba_hist_snapshot sp, dba_tablespaces dt where tsu.tablespace_id= ts.ts# AND tsu.snap_id = sp.snap_id AND ts.tsname = dt.tablespace_name AND sp.begin_interval_time > sysdate-7 GROUP BY TO_CHAR(sp.begin_interval_time,'MM-DD-YYYY'), ts.tsname ORDER BY ts.tsname, days ) a ) b GROUP BY b.tsname ORDER BY b.tsname;
