使用exp导出SYS_P11720分区

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

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
创建表空间

创建表空间
create tablespace p6 datafile '/u01/app/oradata/hou/p6.dbf' size 10M autoextend on next 10M maxsize 31G;
create tablespace p7 datafile '/u01/app/oradata/hou/p7.dbf' size 10M autoextend on next 10M maxsize 31G;

create tablespace p12 datafile '/u01/app/oradata/hou/p12.dbf' size 10M autoextend on next 10M maxsize 31G;
create tablespace p13 datafile '/u01/app/oradata/hou/p13.dbf' size 10M autoextend on next 10M maxsize 31G;
create tablespace p14 datafile '/u01/app/oradata/hou/p14.dbf' size 10M autoextend on next 10M maxsize 31G;
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 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

EXP-00091: Exporting questionable statistics.

Export terminated successfully with warnings.
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。
[oracle@hou-test backup]$ exp part/part file=ANONYMOUSUSER_ALL-ANONY_ALL_2011_05.dmp tables=ANONYMOUSUSER_ALL:ANONY_ALL_2011_05 statistics=none

Export terminated successfully without warnings.
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

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
[oracle@hou-test backup]$ imp 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 ignore=y
