1、我们先查询表空间的占用情况,使用sql如下:

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;

2、查询表空间的数据文件的路径,使用sql如下:

select t.* from sys.dba_data_files t where t.tablespace_name ='PACS31';
