1、查看oracle所有表空间大小
select tablespace_name,sum(bytes)/1024/1024 from dba_data_files group by tablespace_name;
2、oracle未使用的表空间大小
select tablespace_name,sum(bytes)/1024/1024 from dba_free_space group by tablespace_name;
3、使用的表空间大小
select df.tablespace_name,sum(df.bytes)/1024/1024 total,sum(fs.bytes)/1024/1024 free,sum(df.bytes-fs.bytes)/1024/1024 used from dba_data_files df,dba_free_space fs
where df.tablespace_name = fs.tablespace_name
group by df.tablespace_name
