oracle临时表空间地址,Oracle临时表空间查看、添加临时表空间数据文件、修改默认临时表空间 方法...

–查表空间使用率情况(含临时表空间)

SELECT d.tablespace_name “Name”, d.status “Status”,

TO_CHAR (NVL (a.BYTES / 1024 / 1024, 0), ‘99,999,990.90’) “Size (M)”,

TO_CHAR (NVL (a.BYTES - NVL (f.BYTES, 0), 0) / 1024 / 1024,

‘99999999.99’

) USE,

TO_CHAR (NVL ((a.BYTES - NVL (f.BYTES, 0)) / a.BYTES * 100, 0),

‘990.00’

) “Used %”

FROM SYS.dba_tablespaces d,

(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) f

WHERE d.tablespace_name = a.tablespace_name(+)

AND d.tablespace_name = f.tablespace_name(+)

AND NOT (d.extent_management LIKE ‘LOCAL’ AND d.CONTENTS LIKE ‘TEMPORARY’)

UNION ALL

SELECT d.tablespace_name “Name”, d.status “Status”,

TO_CHAR (NVL (a.BYTES / 1024 / 1024, 0), ‘99,999,990.90’) “Size (M)”,

TO_CHAR (NVL (t.BYTES, 0) / 1024 / 1024, ‘99999999.99’) USE,

TO_CHAR (NVL (t.BYTES / a.BYTES * 100, 0), ‘990.00’) “Used %”

FROM SYS.dba_tablespaces d,

(SELECT tablespace_name, SUM (BYTES) BYTES

FROM dba_temp_files

GROUP BY tablespace_name) a,

(SELECT tablespace_name, SUM (bytes_cached) BYTES

FROM v$temp_extent_pool

GROUP BY tablespace_name) t

WHERE d.tablespace_name = a.tablespace_name(+)

AND d.tablespace_name = t.tablespace_name(+)

AND d.extent_management LIKE ‘LOCAL’

AND d.CONTENTS LIKE ‘TEMPORARY’;

查询表空间剩余字节大小

SELECT TABLESPACE_NAME, SUM(BYTES)/1024/1024 AS “FREE SPACE(M)”

FROM DBA_FREE_SPACE

WHERE TABLESPACE_NAME = ‘&tablespace_name’

GROUP BY TABLESPACE_NAME;

注：如果是临时表空间，请查询DBA_TEMP_FREE_SPACE

SELECT TABLESPACE_NAME, FREE_SPACE/1024/1024 AS “FREE SPACE(M)”

FROM DBA_TEMP_FREE_SPACE

WHERE TABLESPACE_NAME = ‘&tablespace_name’;

查询表空间所有数据文件路径

SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS “BYTES(M)”

FROM DBA_DATA_FILES

WHERE TABLESPACE_NAME = ‘&tablespace_name’;

注：如果是临时表空间，请查询DBA_TEMP_FILES

SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS “SPACE(M)”

FROM DBA_TEMP_FILES

WHERE TABLESPACE_NAME = ‘&tablespace_name’;

为空间不足的表空间增加数据文件

ALTER TABLESPACE &tablespace_name ADD DATAFILE ‘&datafile_name’ SIZE 2G;

注：如果要为临时表空间扩容，使用下面的语句

ALTER TABLESPACE &tablespace_name ADD TEMPFILE ‘&datafile_name’ SIZE 2G;

4.查看临时表空间的大小 和 数据文件路径

SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS “SPACE(M)”

FROM DBA_TEMP_FILES

WHERE TABLESPACE_NAME = ‘TEMP’;

或者

select name, bytes/1024/1024 as “大小(M)” from v$tempfile order by bytes;

5.重建并修改默认临时表空间办法：

–查询当前数据库默认临时表空间名

select * from database_properties where property_name=‘DEFAULT_TEMP_TABLESPACE’;

–创建新的临时表空间

create temporary tablespace temp02 tempfile ‘E:\oracle\oradata\lims\TEMP02.DBF’ size 1024M autoextend on;

–修改默认表空间为刚刚建立的临时表空间

alter database default temporary tablespace temp02;

–查看用户所用临时表空间的情况

SELECT USERNAME,TEMPORARY_TABLESPACE FROM DBA_USERS;

–删除原来的临时表空间

drop tablespace temp including contents and datafiles;

–查看所有表空间名确认临时表空间是否已删除

select tablespace_name from dba_tablespaces;
