查询表空间使用率:
SELECT UPPER(F.TABLESPACE_NAME) "表空间名",
D.TOT_GROOTTE_MB "表空间大小(M)",
D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(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 "空闲空间(M)",
F.MAX_BYTES "最大块(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 4 DESC;
查看客户化表的空间占用
SELECT TABLESPACE_NAME,SEGMENT_NAME,TO_CHAR(SUM(BYTES)/(1024*1024),‘999G999D999‘) CNT_MB
FROM DBA_EXTENTS
WHERE OWNER LIKE ‘CUX%‘ AND SEGMENT_NAME LIKE ‘CUX%‘ AND SEGMENT_TYPE LIKE ‘TABLE%‘
GROUP BY TABLESPACE_NAME,SEGMENT_NAME
ORDER BY 3 DESC;
