对SYS_P11720分区进行备份
SQL> select count(*) from ANONYMOUSUSER_ALL partition(SYS_P11720);

  COUNT(*)
----------
     25240

SQL> select CTIME from ANONYMOUSUSER_ALL where rownum<2;

CTIME
------------
01-JUN-11

使用exp导出SYS_P11720分区
[oracle@hou-test backup]$ exp part/part file=ANONYMOUSUSER_ALL_201106.dmp tables=ANONYMOUSUSER_ALL:SYS_P11720

Export: Release 11.1.0.6.0 - Production on Mon Jul 23 06:56:49 2012

About to export specified tables via Conventional Path ...
EXP-00006: internal inconsistency error

出错,exp不支持11g分区表的新特性(ANONYMOUSUSER_ALL是11g的新特性interval分区),解决办法,采用数据泵expd



一、创建dump目录
create directory dump as '/home/oracle/backup';
grant read,write on directory dump to part;

二、备份
1.分区表全表备份
[oracle@hou-test backup]$ expdp part/part directory=dump dumpfile=ANONYMOUSUSER_ALL.dmp tables=ANONYMOUSUSER_ALL

2备份一个分区
[oracle@hou-test backup]$ expdp part/part directory=dump dumpfile=ANONYMOUSUSER_ALL_201106.dmp tables=ANONYMOUSUSER_ALL:SYS_P11720

3.备份多个分区
SQL> select count(*) from ANONYMOUSUSER_ALL partition(SYS_P11721);

  COUNT(*)
----------
     17762

SQL> select ctime from ANONYMOUSUSER_ALL partition(SYS_P11721) where rownum<2;

三、还原
1.分区表整表还原
[oracle@hou-test backup]$ impdp part/part directory=dump dumpfile=ANONYMOUSUSER_ALL.dmp tables=part.ANONYMOUSUSER_ALL

还原出错,通过metalink查到原因,这是11.1.0.6.0版本bug,升级到11.1.0.7.0能解决这个问题,但是生产库就是这个版本,不允许升级。


看来只有放弃interval partition方案了。

使用普通range分区,每个月一个分区,每个分区在一个表空间上
一、准备普通range分区表

create tablespace p15 datafile '/u01/app/oradata/hou/p15.dbf' size 10M autoextend on next 10M maxsize 31G;


授予part用户使用表空间权限
SQL> select 'alter user part quota unlimited on '|| TABLESPACE_NAME||';' from dba_tablespaces where TABLESPACE_NAME like 'P%';

'ALTERUSERPARTQUOTAUNLIMITEDON'||TABLESPACE_NAME||';'
------------------------------------------------------------------
alter user part quota unlimited on P1;
alter user part quota unlimited on P10;
alter user part quota unlimited on P11;
alter user part quota unlimited on P12;
alter user part quota unlimited on P13;
alter user part quota unlimited on P14;
alter user part quota unlimited on P15;
alter user part quota unlimited on P2;
alter user part quota unlimited on P3;
alter user part quota unlimited on P4;
alter user part quota unlimited on P5;
alter user part quota unlimited on P6;
alter user part quota unlimited on P7;
alter user part quota unlimited on P8;
alter user part quota unlimited on P9;

2.分区表一个分区的备份还原
2.1备份一个分区
比如备份ANONY_ALL_2011_05分区
[oracle@hou-test backup]$ exp part/part file=ANONYMOUSUSER_ALL-ANONY_ALL_2011_05.dmp tables=ANONYMOUSUSER_ALL:ANONY_ALL_2011_05

导出时报错,解决办法1:
指定Linux系统的NLS_LANG环境变量为数据库的数据集
SQL>  select userenv('language') from dual;

USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

[oracle@hou-test backup]$ set NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
[oracle@hou-test backup]$ export set NLS_LANG=AMERICAN_AMERICA.ZHS16GBK


再次导出
[oracle@hou-test backup]$ exp part/part file=ANONYMOUSUSER_ALL-ANONY_ALL_2011_05.dmp tables=ANONYMOUSUSER_ALL:ANONY_ALL_2011_05

依然报错,看来不大适用分区表

解决办法2:使用statistics=none,也就是不导出统计信息。

2.2还原一个分区
truncate ANONY_ALL_2011_05分区
SQL> alter table ANONYMOUSUSER_ALL truncate partition ANONY_ALL_2011_05 update indexes;

Table truncated.

还原
[oracle@hou-test backup]$ imp part/part file=ANONYMOUSUSER_ALL-ANONY_ALL_2011_05.dmp tables=ANONYMOUSUSER_ALL:ANONY_ALL_2011_05 ignore=y

3.同时备份和还原多个分区
2.1备份多个分区,ANONYMOUSUSER_ALL的ANONY_ALL_2011_07和ANONY_ALL_2011_08分区。
[oracle@hou-test backup]$ exp part/part file=ANONY_ALL_2011_07-ANONY_ALL_2011_08.dmp tables=ANONYMOUSUSER_ALL:ANONY_ALL_2011_07,ANONYMOUSUSER_ALL:ANONY_ALL_2011_08  statistics=none

Export terminated successfully without warnings.

2.2导入多个分区
truncate这两个分区
SQL> alter table ANONYMOUSUSER_ALL truncate partition ANONY_ALL_2011_07 update indexes;

Table truncated.

SQL> alter table ANONYMOUSUSER_ALL truncate partition ANONY_ALL_2011_08 update indexes;

Table truncated.

导入
