查看表空间使用情况

查看表空间使用情况
方法一：
SELECT a.tablespace_name,
a.bytes/1024/1024 total,
b.bytes/1024/1024 used,
c.bytes/1024/1024 free,
(b.bytes * 100) / a.bytes "% USED ",
(c.bytes * 100) / a.bytes "% FREE "
FROM sys.sm$ts_avail a, sys.sm$ts_used b, sys.sm$ts_free c
WHERE a.tablespace_name = b.tablespace_name
AND a.tablespace_name = c.tablespace_name;

方法二：
SELECT a.tablespace_name "表空间名",
total "表空间大小",
free "表空间剩余大小",
(total - free) "表空间使用大小",
total / (1024 * 1024 * 1024) "表空间大小(G)",
free / (1024 * 1024 * 1024) "表空间剩余大小(G)",
(total - free) / (1024 * 1024 * 1024) "表空间使用大小(G)",
round((total - free) / total, 4) * 100 "使用率 %"
FROM (SELECT tablespace_name, SUM(bytes) free
FROM dba_free_space
GROUP BY tablespace_name) a,
(SELECT tablespace_name, SUM(bytes) total
FROM dba_data_files
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name

TEMP 零时表空间使用情况查询

SELECT D.tablespace_name,
       SPACE "SUM_SPACE(M)",
       blocks "SUM_BLOCKS",
       used_space "USED_SPACE(M)",
       Round(Nvl(used_space, 0) / SPACE * 100, 2) "USED_RATE(%)",
       SPACE - used_space "FREE_SPACE(M)"
  FROM (SELECT tablespace_name,
               Round(SUM(bytes) / (1024 * 1024), 2) SPACE,
               SUM(blocks) BLOCKS
          FROM dba_temp_files
         GROUP BY tablespace_name) D,
       (SELECT tablespace,
               Round(SUM(blocks * 8192) / (1024 * 1024), 2) USED_SPACE
          FROM v$sort_usage
         GROUP BY tablespace) F
WHERE D.tablespace_name = F.tablespace(+)
   --AND D.tablespace_name in ('TEMP', 'TEMP1')
