一.查看表空间大小
select dbf.tablespace_name,
dbf.totalspace "总量(G)",
dbf.totalblocks as 总块数,
dfs.freespace "剩余总量(G)",
dfs.freeblocks "剩余块数",
(dfs.freespace / dbf.totalspace) * 100 "空闲比例"
from (select t.tablespace_name,
sum(t.bytes) / 1024 / 1024 / 1024 totalspace,
sum(t.blocks) totalblocks
from dba_data_files t
group by t.tablespace_name) dbf,
(select tt.tablespace_name,
sum(tt.bytes) / 1024 / 1024 / 1024 freespace,
sum(tt.blocks) freeblocks
from dba_free_space tt
group by tt.tablespace_name) dfs
where trim(dbf.tablespace_name) = trim(dfs.tablespace_name);
