Oracle表空間佔用情況

1.表空間使用量

SELECT Upper(F.TABLESPACE_NAME)                                                                        "表空間名",

2.TEMP表空間使用量

       SPACE "SUM_SPACE(M)",
       USED_SPACE "USED_SPACE(M)",
       ROUND(NVL(USED_SPACE, 0) / SPACE * 100, 2) "USED_RATE(%)",

  FROM (SELECT FILE_ID,
               FILE_NAME,

               SUM(BLOCKS) BLOCKS
          FROM DBA_TEMP_FILES
         GROUP BY TABLESPACE_NAME, FILE_ID, FILE_NAME) D,
       (SELECT FILE_ID,
               TABLESPACE_NAME,
               ROUND(SUM(BYTES_USED) / (1024 * 1024), 2) USED_SPACE,
               ROUND(SUM(BYTES_FREE) / (1024 * 1024), 2) FREE_SPACE
          FROM V$TEMP_SPACE_HEADER
         GROUP BY TABLESPACE_NAME, FILE_ID) E,
       (SELECT FILE_ID, AUTOEXTENSIBLE FROM DBA_TEMP_FILES) F
 WHERE D.TABLESPACE_NAME = E.TABLESPACE_NAME(+)
   AND D.FILE_ID = E.FILE_ID(+)
   AND D.FILE_ID = F.FILE_ID(+)
 ORDER BY TABLESPACE_NAME, FILE_NAME;
