oracle传输表空间功能测试（含详细过程）

最近做数据迁移，之前有一篇迁移思路思考的文章，这里继续做具体的测试，主题问表空间传输。

一、源服务器上导出表空间

源服务器:   10.1.122.55
目标服务器：10.1.122.54

0.设置字符集

注意，这里不设置字符集在导入的时候会报错，详细情况见文章的最后。
suse11sp2:~ # export LANG=AMERICAN_AMERICA.AL32UTF8
suse11sp2:~> export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

suse11sp2:~> sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jul 24 14:45:47 2013

1.准备需要传输的表空间

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create tablespace aaa datafile '/oracle/oradata/aa.dbf' size 100M ;

Tablespace created.

SQL> CREATE USER aaa  IDENTIFIED BY aaa
DEFAULT TABLESPACE aaa
TEMPORARY TABLESPACE  temp;   2    3

User created.

SQL> GRANT CONNECT,RESOURCE TO aaa;

Grant succeeded.

SQL> REVOKE UNLIMITED TABLESPACE FROM aaa;

Revoke succeeded.

SQL> ALTER USER aaa QUOTA UNLIMITED ON aaa;

User altered.

SQL> conn aaa/aaa;
Connected.
SQL> create table a1(id varchar2(10),name varchar2(20));

Table created.

SQL> insert into a1 values('01','lurou');

1 row created.

SQL> insert into a1 values('02','hello,DBA!');

1 row created.

SQL> COMMIT;

Commit complete.

SQL> select * from a1;

ID         NAME
---------- --------------------
01         lurou
02         hello,DBA!

SQL>
SQL>
SQL>

2.做传输前检查

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

PL/SQL procedure successfully completed.

SQL>
SQL> select * from sys.transport_set_violations;

no rows selected

SQL>

3.设置表空间为只读

SQL>
SQL> alter tablespace aaa read only;

Tablespace altered.

SQL>
SQL> commit;

Commit complete.

SQL>

4.导出表空间

1）遇到个小插曲，必须使用sys dba
suse11sp2:~> exp system/its7888$ tablespaces=aaa file=/tmp/aaatts.dmp  transport_tablespace=y

Export: Release 11.2.0.3.0 - Production on Wed Jul 24 14:58:19 2013

Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
EXP-00044: must be connected 'AS SYSDBA' to do Point-in-time Recovery or Transportable Tablespace import
EXP-00000: Export terminated unsuccessfully

2）导出成功
suse11sp2:~> exp \'sys/its7888$ as sysdba\' tablespaces=aaa file=/tmp/aaatts.dmp transport_tablespace=y

Export: Release 11.2.0.3.0 - Production on Wed Jul 24 14:59:13 2013

Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.

Note: table data (rows) will not be exported

For tablespace AAA ...
. exporting cluster definitions
. exporting table definitions
. . exporting table                             A1
. exporting referential integrity constraints
. exporting triggers
. end transportable tablespace metadata export
Export terminated successfully without warnings.
suse11sp2:~>

二、目标服务器上导入表空间

5.将导出的dmp文件和数据文件拷贝到目标服务器

scp /oracle/oradata/aa.dbf oracle@10.1.122.54:/oracle/oradata
scp /tmp/aaatts.dmp  oracle@10.1.122.54:/tmp

6.创建用户

SQL> create user bbb identified by bbb;

User created.

SQL> grant connect,resource to bbb;

Grant succeeded.

SQL> commit;

Commit complete.

7.导入表空间

imp \'sys/its7888$ as sysdba\'  tablespaces=aaa transport_tablespace=y file=/tmp/aaatts.dmp  datafiles=/oracle/oradata/aa.dbf  fromuser=aaa touser=bbb

SQL> conn aaa/aaa
Connected.
SQL> select * from a1
  2  ;

ID         NAME
---------- --------------------
01         lurou
02         hello,DBA!

SQL>
SQL>
SQL> conn / as sysdba
Connected.
SQL> drop tablespace aaa including contents and datafiles;

Tablespace dropped.

三、之前遭遇的报错

未设置字符集的操作过程中，遭遇报错

suse11sp2:~> exp \'sys/its7888$ as sysdba\' tablespaces=aaa file=/tmp/aaatts.dmp transport_tablespace=y

Export: Release 11.2.0.3.0 - Production on Wed Jul 24 15:31:57 2013
