内容简介：Oracle 12r2 数据库之间传输表，分区或子分区
在Oracle 12cr2中，可以使用传输表功能来从一个数据库中复制一组表，分区或子分区到另一个数据库中。传输表操作将会指定表，分区或子分区的元数据移到另一个数据库中。传输表操作会自动识别所指定表所在的表空间。为了移动数据，需要将这些表所在表空间的所有数据文件复制到目标数据库。Data Pump导入会自动释放由表，分区或子分区所占有的数据块，这些数据块不是传输表操作的一部分。
可以使用以下方法来传输表，分区或子分区:
.使用导出dump文件
在执行导出时，指定tables参数并且设置transportable参数为always。在执行导入时，不需要指定transportable参数。Data Pump导入会自动识别传输表操作。
.跨网络
在执行导入时，指定tables参数并且设置transportable参数为always,并且指定network_link参数来指定数据链路
传输表操作的限制
.不能将相同方案中相同表名的表传输到目标数据库中。然而可以使用remap_table导入参数来将表中的数据导入到不同的表中。另外，在传输操作执行之前，可以重命名被传输表或目标表。
.对于加密有以下限制:
–不能传输加密表空间中的表
–不能包含加密列的表
.不能在使用不同的time zone文件版本的不同平台之间传输使用timestamp with timezone的表
使用导出dump文件方式来传输表，分区，或子分区
在数据库之间使用志出dump文件来传输表需要执行以下步骤。
1.选择一组表，分区或子分区。
如果是要传输分区，那么在传输表操作中可以指定一个表的分区，并且在同一操作中没有其它的表将被传输。如果在传输表操作中中只有表分区的子集被导出，那么在导入后每个分区将变成非分区表。
2.在源数据库中，将要被传输的表，分区或子分区所在表空间设置为只读模式。为了查询表所在的表空间可以查询dba_tables视图，为了查询表空间的所有文件可以查询dba_data_files视图。
3.执行Data Pump导出
4.传输导出的dump文件，将导出的dump文件复制到目标数据库并且让其可以访问。
5.传输表，分区或子分区所在表空间的所有数据文件到目标数据库。如果源平台与目标平台的字节编码不一样，那么可以使用以下任何一种方法来转换数据文件。
–使用dbms_file_transfer包中的get_file或put_file过程来传输数据文件，它们会自动将数据文件转换为目标平台的字节编码。
–使用rman的convert命令来将数据文件转换为目标平台的字节编码。
6.可选操作，将源数据库中的表空间设置为读写模式
7.在目标数据库上执行导入操作
下面的例子将分区表sh.sales_test表中的部分分区(sales_test_q1_2000,sales_test_q2_2000)传输到目标数据库中。源平台与目标平台字节编码一样，都是 linux 64位操作系统
1.先创建分区表sales_test
SQL> create tablespace sales_test datafile '+DATADG/jyrac/datafile/sales_test_01.dbf' size 100M autoextend off extent management local segment space management auto;
Tablespace created
-- Create table
create table SH.SALES_TEST

prod_id /* NUMBER not null*/,
cust_id /*NUMBER not null*/,
time_id /*DATE not null*/,
channel_id /*NUMBER not null*/,
promo_id /*NUMBER not null*/,
quantity_sold /*NUMBER(10,2) not null*/,
amount_sold /*NUMBER(10,2) not null*/
)
partition by range (TIME_ID)
