添加表空間步驟

1.查看那些表空間滿

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;


2.查出該表空間中的數據文件位置
select FILE_NAME,TABLESPACE_NAME from dba_data_files WHERE TABLESPACE_NAME LIKE '**' order by TABLESPACE_NAME;


3.添加數據文件：

alter tablespace ******
add datafile '' size 20480m;
