1、查看表空间占用情况

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') || '%' "使用率",

  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 "使用率" desc;

2、查看对应的表空间占用最高的前10个数据:

SELECT *

FROM (SELECT BYTES, segment_name, segment_type, owner

FROM dba_segments

WHERE tablespace_name = 'SYSTEM'

ORDER BY BYTES DESC)

WHERE ROWNUM < 100;
