客户有一台服务器，上面建了两个实例，打算整合成一个库，两个库没有同名的用户、表空间、数据文件，这就很好弄了，EXP/EXPDP导入导出就可以，传输表空间(TTS transport tablespace)也可以，考虑到客户的服务器没有存放备份的空闲空间，所以使用传输表空间(TTS transport tablespace)来做这个事情。
由于客户环境表空间较多，单个表空间传输肯定不行，所以，把需要的表空间一起迁移过去。而且，两个实例的block szie不一样，需要设置参数。
测试环境：OEL5.7 ORACLE10.2.0.4.0
迁出实例EOSP，block szie 16K
迁入实例source，block szie 8K
下面进行测试，EOSP数据库创建测试用户和表空间。

SQL> create tablespace test1 datafile '/data/eosp/test01.dbf' size 10M;

Tablespace created.

SQL> create tablespace test2 datafile '/data/eosp/test02.dbf' size 10M;

Tablespace created.

SQL> create tablespace test3 datafile '/data/eosp/test03.dbf' size 10M;

Tablespace created.

SQL> create tablespace test4 datafile '/data/eosp/test04.dbf' size 10M;

Tablespace created.

SQL> create tablespace index1 datafile '/data/eosp/index01.dbf' size 10M;

Tablespace created.

SQL> create user user1 identified by user1 default tablespace test1;

User created.

SQL> create user user2 identified by user2 default tablespace test2;

User created.

SQL> grant connect,resource to user1;

Grant succeeded.

SQL> grant connect,resource to user2;

Grant succeeded.

user1用户创建测试数据，创建分区表分布在test1、test2、test3、test4表空间上。

SQL> conn user1/user1
Connected.

SQL> create table test1(id number,name varchar2(10))
  2  partition by list(id)
  3  (partition p1 values(1) tablespace test1,
  4  partition p2 values(2) tablespace test2,
  5  partition p3 values(3) tablespace test3,
  6  partition p4 values(default) tablespace test4);

Table created.

SQL> insert into test1 values(1,'zhangsan');

1 row created.

SQL> insert into test1 values(2,'lisi');

1 row created.

SQL> insert into test1 values(3,'wangwu');

1 row created.

SQL> insert into test1 values(4,'zhaoliu');

1 row created.

SQL> commit;

Commit complete.

SQL> select * from test1 partition(p1);

        ID NAME
---------- ----------
         1 zhangsan

SQL> select * from test1 partition(p2);

        ID NAME
---------- ----------
         2 lisi

SQL> select * from test1 partition(p3);

        ID NAME
---------- ----------
         3 wangwu

SQL> select * from test1 partition(p4);

        ID NAME
---------- ----------
         4 zhaoliu


SQL> create index ind1 on test1(id) local tablespace index1;

Index created.

SQL> select segment_name,partition_name,tablespace_name from dba_segments where owner='USER1';

SEGMENT_NAME         PARTITION_NAME                 TABLESPACE_NAME
-------------------- ------------------------------ ------------------------------
TEST1                P1                             TEST1
TEST1                P2                             TEST2
TEST1                P3                             TEST3
TEST1                P4                             TEST4
IND1                 P4                             INDEX1
IND1                 P3                             INDEX1
IND1                 P2                             INDEX1
IND1                 P1                             INDEX1

user2用户重复上面的操作即可，同样数据会分散到所有的这些表空间上。

SQL> conn user2/user2
Connected.
SQL>
SQL>
SQL> create table test1(id number,name varchar2(10))
  2  partition by list(id)
  3  (partition p1 values(1) tablespace test1,
  4  partition p2 values(2) tablespace test2,
  5  partition p3 values(3) tablespace test3,
  6  partition p4 values(default) tablespace test4);

Table created.

SQL> insert into test1 values(1,'zhangsan');

1 row created.

SQL> insert into test1 values(2,'lisi');

1 row created.

SQL> insert into test1 values(3,'wangwu');

1 row created.

SQL> insert into test1 values(4,'zhaoliu');

1 row created.

SQL> commit;

Commit complete.

SQL>
SQL>
SQL>
SQL> create index ind1 on test1(id) local tablespace index1;

Index created.

这时候如果只迁移一个表空间是不可以的，检查时就会给出提示。

SQL> conn / as sysdba
Connected.
SQL> exec sys.dbms_tts.transport_set_check('test1',true);

PL/SQL procedure successfully completed.

SQL> select * from sys.transport_set_violations;

VIOLATIONS
----------------------------------------------------------------------------------------------------
Default Partition (Table) Tablespace TEST2 for TEST1 not contained in transportable set
Partitioned table USER1.TEST1 is partially contained in the transportable set: check table partition
s by querying sys.dba_tab_partitions

Default Partition (Table) Tablespace TEST3 for TEST1 not contained in transportable set
Default Partition (Table) Tablespace TEST2 for TEST1 not contained in transportable set
Default Partition (Table) Tablespace TEST4 for TEST1 not contained in transportable set
Partitioned table USER2.TEST1 is partially contained in the transportable set: check table partition
s by querying sys.dba_tab_partitions

所以，需要将这些表空间一起传输过去才可以，一起传输校验，就不会有问题。

SQL> exec sys.dbms_tts.transport_set_check('TEST1,TEST2,TEST3,TEST4,INDEX1',TRUE,TRUE);

PL/SQL procedure successfully completed.

SQL> select * from sys.transport_set_violations;

no rows selected

下面开始测试，迁移前，需要把需要迁移的表空间设置成只读模式，防止数据文件在迁移过程中被修改。

SQL> alter tablespace test1 read only;

Tablespace altered.

SQL> alter tablespace test2 read only;

Tablespace altered.

SQL> alter tablespace test3 read only;

Tablespace altered.

SQL> alter tablespace test4 read only;

Tablespace altered.

SQL> alter tablespace index1 read write

Tablespace altered.

然后就可以通过exp或expdp导出这些表空间的元数据了。

[oracle@source ~]$ export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

将这些表空间对应的数据文件复制(或者move)到迁入数据库(source)的目录下(也可以在当前路径下)。

[oracle@source source]$ cd /u01/app/oracle/oradata/source
[oracle@source source]$ cp /data/eosp/test0* .
[oracle@source source]$ cp /data/eosp/index01.dbf .

迁入数据库创建用户并授权。

SQL> create user user1 identified by user1;

User created.

SQL> create user user2 identified by user2;

User created.

SQL> grant connect,resource to user1;

Grant succeeded.

SQL> grant connect,resource to user2;

Grant succeeded.

开始迁入表空间。

迁出库(EOSP)将表空间设置为读写模式。

SQL> alter tablespace test1 read write;

Tablespace altered.

SQL> alter tablespace test2 read write;

Tablespace altered.

SQL> alter tablespace test3 read write

Tablespace altered.

SQL> alter tablespace test4 read write

Tablespace altered.

SQL> alter tablespace index1 read write

Tablespace altered.

然后关闭迁出库(EOSP)，修改应用连接的服务名，验证应用是否可正常访问数据库。
