use EM or Toad or any other Tool
Or else u can use these queries :
1)
select a.TABLESPACE_NAME,
a.BYTES bytes_used,
b.BYTES bytes_free,
b.largest,
round(((a.BYTES-b.BYTES)/a.BYTES)*100,2) percent_used
from
(
select TABLESPACE_NAME,
sum(BYTES) BYTES
from dba_data_files
group by TABLESPACE_NAME
)
a,
(
select TABLESPACE_NAME,
sum(BYTES) BYTES ,
max(BYTES) largest
from dba_free_space
group by TABLESPACE_NAME
)
b
where a.TABLESPACE_NAME=b.TABLESPACE_NAME
order by ((a.BYTES-b.BYTES)/a.BYTES) desc
2)
CLEAR
SET HEAD ON
SET VERIFY OFF
spool frt1
col tspace form a25 Heading "Tablespace"
col tot_ts_size form 99999999999999 Heading "Size (Mb)"
col free_ts_size form 99999999999999 Heading "Free (Mb)"
col ts_pct form 9999 Heading "% Free"
col ts_pct1 form 9999 Heading "% Used"
break on report
compute sum of free_ts_size on report
compute sum of tot_ts_size on report
SELECT /* + RULE */ df.tablespace_name tspace,
df.bytes/(1024*1024) tot_ts_size,
sum(fs.bytes)/(1024*1024) free_ts_size,
nvl(round(sum(fs.bytes)*100/df.bytes),1) ts_pct,
round((df.bytes-sum(fs.bytes))*100/df.bytes) ts_pct1
FROM dba_free_space fs
, (select tablespace_name, sum(bytes) bytes
from dba_data_files group by tablespace_name ) df

Vikhar you can use...
select f.tablespace_name,f.bytes/(1024*1024),u.bytes/(1024*1024) from sm$ts_free f,sm$ts_used u where f.tablespace_name=u.tablespace_name;
when are you comming to SA
