一、表空間使用狀況oracle
SELECT UPPER(F.TABLESPACE_NAME) "表空間名",
D.TOT_GROOTTE_MB "表空間大小(M)",
D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空間(M)",
TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100,2),'990.99') || '%' "使用比",
F.TOTAL_BYTES "空閒空間(M)",
F.MAX_BYTES "最大塊(M)"
FROM (SELECT TABLESPACE_NAME,
ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,
ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES
FROM SYS.DBA_FREE_SPACE
GROUP BY TABLESPACE_NAME) F,
(SELECT DD.TABLESPACE_NAME,
ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB
FROM SYS.DBA_DATA_FILES DD
GROUP BY DD.TABLESPACE_NAME) D
WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME
ORDER BY 1;app
二、表空間地址spa
select * from dba_data_files where tablespace_name='JSDT_DATA';table
三、file
增長表空間文件select
alter tablespace JSDT_DATA add datafile '/home/oracle/app/product/11.2/db/dbs/homeoracleapporadatadtposJSDT_DATA4.dbg' size 20480M autoextend off;db
四、查看錶空間表格使用狀況tab
select segment_name,bytes/1024/1024 from dba_segments where tablespace_name
='JSDT_DATA' and segment_type='TABLE';文件
