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 Copyright (c) 1982, 2011, Oracle. All rights reserved. |
1.准备需要传输的表空间
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
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
|
1 2 3 4 5 6 7 8 9 10 11 12 |
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
|
1 2 3 4 5 6 7 8 9 |
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
|
1 2 3 4 5 6 7 8 |
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.

2）导出成功
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
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.

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
|
1 2 |
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
|
1 2 3 4 5 6 7 8 |
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
|
1 2 3 4 5 6 |
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 |
|
1 2 3 4 5 6 7 8 9 10 11 12 |
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
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |
