1、查询表空间使用率:

select * from (
Select a.tablespace_name,
to_char(a.bytes/1024/1024,'99,999.999') total_bytes,
to_char(b.bytes/1024/1024,'99,999.999') free_bytes,
to_char(a.bytes/1024/1024 - b.bytes/1024/1024,'99,999.999') use_bytes,
to_char((1 - b.bytes/a.bytes)*100,'99.99') || '%'use
from (select tablespace_name,
sum(bytes) bytes
from dba_data_files
group by tablespace_name) a,
(select tablespace_name,
sum(bytes) bytes
from dba_free_space
group by tablespace_name) b
where a.tablespace_name = b.tablespace_name
union all
select c.tablespace_name,
to_char(c.bytes/1024/1024,'99,999.999') total_bytes,
to_char( (c.bytes-d.bytes_used)/1024/1024,'99,999.999') free_bytes,
to_char(d.bytes_used/1024/1024,'99,999.999') use_bytes,
to_char(d.bytes_used*100/c.bytes,'99.99') || '%'use
from
(select tablespace_name,sum(bytes) bytes
from dba_temp_files group by tablespace_name) c,
(select tablespace_name,sum(bytes_cached) bytes_used
from v$temp_extent_pool group by tablespace_name) d
where c.tablespace_name = d.tablespace_name
)
order by tablespace_name

发现表空间使用率100%。
2、使用11g表空间收缩表空间,降低使用率,sql语句:ALTER TABLESPACE TEMP SHRINK SPACE
3、查看到temp表空间大小变为1.99M,使用率0%;
查询路径临时文件路径select d.file_name,d.tablespace_name,d.autoextensible from dba_temp_files d;
4、需添加临时数据文件,设置大小,sql语句如下: alter tablespace temp add tempfile '/oracle/oradata/dbaxj/temp02.dbf' size 10240m autoextend on next 1024m maxsize 30G;
