3. 表空间传输:
更多关于表空间传输的内容:http://blog.csdn.net/bamuta/article/category/1138527验证表空间的自包含:
SQL> exec dbms_tts.transport_set_check('TAN_2013_9',TRUE);
PL/SQL procedure successfully completed.
SQL> select * from transport_set_violations;
no rows selected
另外表空间传输需要两端库的字符集一致。
导出无数据:
SQL> alter tablespace tan_2013_9 read only;
[oracle@OEL63 ~]$ exp \'sys/oracle as sysdba\' tablespaces=tan_2013_9 transport_tablespace=y file=exp_tan_2013_9.dmp拷贝文件
[oracle@OEL63 ~]$ scp exp_tan_2013_9.dmp 192.168.114.174:/home/oracle/
[oracle@OEL63 ~]$ scp /data01/qing/QING/datafile/o1_mf_tan_2013_9tht2cgh_.dbf 192.168.114.174:/data01/vm603/VM603/datafile/
在目标库导入元数据
[oracle@vm603 ~]$ imp \'sys/oracle as sysdba\' transport_tablespace=y file=exp_tan_2013_9.dmp log=imp.log tablespaces=tan_2013_9 datafiles='/data01/vm603/VM603/datafile/o1_mf_tan_2013_9tht2cgh_.dbf'
将两端库的该表空间read write
SQL> alter tablespace tan_2013_9 read write;
4.目标库再做分区交换
目标库对就表增加分区:SQL> alter table tan add partition tan_2013_9 values less than (to_date('2013-10-01','yyyy-mm-dd')) tablespace tan_2013_9;
Table altered.
SQL> select count(*) from tan partition(tan_2013_9);
COUNT(*)
----------0
在目标库做一次分区交换。
SQL> alter table tan exchange partition tan_2013_9 with table tmp_tan_2013_9 including indexes with validation;
Table altered.
检查
SQL> select count(*) from tan partition(tan_2013_9);
COUNT(*)
----------
833
SQL> select table_name,partition_name,tablespace_name from user_tab_partitions;
TABLE_NAME PARTITION_NAME TABLESPACE_NAME
------------------------------ ------------------------------ ------------------------------
TAN TAN_2013_8 TAN_2013_8
TAN TAN_2013_7 TAN_2013_7
TAN TAN_2013_9 TAN_2013_9
SQL> select index_name,partition_name,tablespace_name from user_ind_partitions;
INDEX_NAME PARTITION_NAME TABLESPACE_NAME
------------------------------ ------------------------------ ------------------------------
IND_TAN IND_TAN_2013_8 TAN_2013_8
IND_TAN IND_TAN_2013_7 TAN_2013_7
IND_TAN TAN_2013_9 TAN_2013_9
5.源库删掉已经迁移走的分区:
SQL> select table_name,partition_name,tablespace_name from user_tab_partitions; TABLE_NAME PARTITION_NAME TABLESPACE_NAME ------------------------------ ------------------------------ ------------------------------ TAN TAN_2014_3 TAN_2014_3 TAN TAN_2014_2 TAN_2014_2 TAN TAN_2014_4 TAN_2014_4 TAN TAN_2014_5 TAN_2014_5 TAN TAN_2014_6 TAN_2014_6 TAN TAN_2014_7 TAN_2014_7 TAN TAN_2014_8 TAN_2014_8 TAN TAN_2013_10 TAN_2013_10 TAN TAN_2013_11 TAN_2013_11 TAN TAN_2013_12 TAN_2013_12 TAN TAN_201
