测试环境磁盘空间不足,所以drop一些无用的大表,但是发现空间没有变化,df -h还是没有释放出磁盘空间来。

SQL> set line 200

SQL> set pagesize 200

SQL> col name format A150

 

 

1,查看表空间使用情况

SQL> SELECTUPPER(F.TABLESPACE_NAME) "表空间名",
  2          D.TOT_GROOTTE_MB "表空间大小(M)",
  3          D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)",
  4          TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) /D.TOT_GROOTTE_MB * 100,2),‘990.99‘) || ‘%‘ "使用比",
  5          F.TOTAL_BYTES "空闲空间(M)",
  6          F.MAX_BYTES "最大块(M)"
  7          FROM (SELECT TABLESPACE_NAME,
  8          ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,
  9          ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES
 10          FROM SYS.DBA_FREE_SPACE
 11          GROUP BY TABLESPACE_NAME) F,
 12          (SELECT DD.TABLESPACE_NAME,
 13           ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB
 14          FROM SYS.DBA_DATA_FILES DD
 15          GROUP BY DD.TABLESPACE_NAME) D
 16          WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME
 17          ORDER BY 1;

看到ORCTSTU表空间只使用了49%,使用了15G空间,而ORCTSTU表空间占据的总磁盘空间为32G,所以我们可以收缩ORCTSTU到16G左右,这样就释放出了将近16G的空间了。

 

去查看下此表空间所在的数据文件,如下所示:

SQL> SELECT file_id,file_name FROM DBA_DATA_FILES D WHERED.TABLESPACE_NAME = ‘ORCTSTU‘;
   FILE_ID FILE_NAME
------------------------------------------------------------------------------------------
         5D:\ORACLE\ORASERVER\ORADATA\ORCTSTUEX\POWERDES\ORCTSTU01.DBF

2resize收缩报错:

准备收缩到18G,执行如下报错

SQL> alter database datafile‘/home/oradata/powerdes/orctstu01.dbf‘ resize 1800M;              

alter database datafile‘/home/oradata/powerdes/orctstu01.dbf‘ resize 1800M

*

ERROR at line 1:

ORA-03297: file contains used data beyondrequested RESIZE value

 

 

SQL>

 

 

 参考命令:

select file_id,max(block_id+blocks-1)HWM,block_id

            from dba_extents

            where file_id=5

            group by file_id,block_id;

                                                 

 

 

3,去分析情况这个数据文件

可以看到基本没有任何改变,但是根据我的直观感觉,确实没有多少表了,空间也确实都腾出来了。可以简单的验证一下,数据文件是5号,使用dba_extents可以看到占用的空间情况和对应的块的情况。

                                                 

select file_id,max(block_id+blocks-1)HWM,block_id

            from dba_extents

            where file_id=5

            group by file_id,block_id;

                                 

6519       5              4194047                4193920

3469       5              4187263                4186368

8137       5              4186367                4186240

3919       5              4186239                4186112

3033       5              4186111                4185984

9526       5              4185983                4185856

9113       5              4185855                4184832

9669       5              4184775                4184768

1166       5              4184767                4184760

2304       5              4184743                4184736

7215       5              4184735                4184728

4933       5              4184727                4184720

......

 

通过对比HWM和block_id的值,看到有很多都是空间占用差别比较大的。

 

4,查看以下数据文件的最大的block_id

我们来在这个基础上做一个简单的分析。首先得到5号数据文件中,块号最大的数据块block_id。

 

SQL> SELECT MAX(block_id) FROMdba_extents WHERE tablespace_name = ‘ORCTSTU‘;

 

MAX(BLOCK_ID)

-------------

     4193920

 

SQL>    

值为:  4193920

 

再查看下一个block的容量大小

SQL> show parameter db_block_size;

 

NAME                                                         TYPE           VALUE

----------------------------------------------- ------------------------------

db_block_size                                           integer       8192

SQL>

 

5,根据这个值查看对于的数据文件所占据的磁盘空间大小

 SELECT 4193920*8192/1024/1024 FROM dual;

SQL> SELECT 4193920*8192/1024/1024/1024FROM dual;

 

4193920*8192/1024/1024/1024

---------------------------

                                 31.9970703

 

SQL>

计算出来大概是32G左右,再去磁盘看实际的数据文件大小

[oracle@edustu4 ~]$ ll -h/home/oradata/powerdes/orctstu01.dbf

-rw-r-----. 1 oracle oinstall 32G May 1618:06 /home/oradata/powerdes/orctstu01.dbf

[oracle@edustu4 ~]$

 

也是32G左右,和实际的磁盘的数据文件的大小一致,

 

看看这个最大4193920的数据块所在的extent对应的segment信息是否是已经被drop到的table?

select segment_name,owner from dba_extentswhere block_id=3507584;  

SQL> select segment_name,owner fromdba_extents where block_id=1942656; 

 

SEGMENT_NAME

--------------------------------------------------------------------------------

OWNER

------------------------------

RES_APPROVE_SHARE

ORCTSTU

 

 

SQL>

 

6,分析问题所在

这个表不是一件被drop的哪些表记录,表RES_APPROVE_SHARE正在被应用程序使用着,也就说明了报错,所以resize的时候报错ORA-03297: file contains used data beyond requested RESIZE value,block不能释放掉,因为正在被使用。

 

这个时候通过正常的resize已经不能解决问题了,怎么办?可以采用expdp、impdp的方式重新生成新的表空间和数据文件,然后删除旧的表空间和数据文件。

 

7,开始新建表空间

create tablespace ORCTSTU_2 

logging 

datafile ‘/home/oradata/powerdes/orctstu02.dbf‘

size 50m 

autoextend on 

next 50m ;

alter table RES_APPROVE_SHARE move ORCTSTU_2;

 

ORA-14133: ALTER TABLE MOVE cannot becombined with other operations

 

alter table orctstu.RES_APPROVE_SHARE movetablespace ORCTSTU_2;

 

8,使用expdp导出数据

                先建立管道目录

                CREATEOR REPLACE DIRECTORY dir_dump_t1  AS‘/home/oracle/expdpimpdp‘;

               

                开始导出export

                                [oracle@edustu4~]$ expdp  orctstu/testpd2015@PD1directory=dir_dump_t1 schemas=orctstu dumpfile=TEST2_PD_20150518.dmp

9,开始使用import导入数据

9.1 清理旧数据

删除用户

                 drop user orctstu cascade;

                 删除表空间

                 drop tablespace orctstu including contents anddatafiles;

                 然后重启oracle

                 shutdown immediate

                 startup

                 查看磁盘空间,已经释放出来了

9.3 开始导入备份的数据

导入命令:

                impdporctstu/testpd2015@PD1 directory=dir_dump_t1 dumpfile=TEST2_PD_20150518.dmpnologfile=y

 

                导入过程如下:

                ......

                PS:impdp导入的时候,是从最大的表开始导入的,先导入数据,最后重建索引,导入各种其它objects

                 

 

10,报错记录
