oracle可传输表空间:导入导出
实验环境： 源数据库服务器名：beijing 数据库全局名和SID：orcl
辅助数据库:suzhou 只安装数据库软件，没有新建数据库
在辅助服务器suzhou上复制一个例程名和数据库名都是bj的数据库.

------------------------------------------------------
0.源数据库服务器上新建备份目录
mkdir f:\backup
mkdir f:\dump
1.源数据库和目标数据库检测
set oracle_sid=orcl
col name heading '实例名' for a10 col version heading '数据库版本' for a15 col
platform_name heading '操作系统平台' for a30 col endian_format heading
'字节顺序' for a15
SELECT d.NAME, i.VERSION, d.PLATFORM_NAME, ENDIAN_FORMAT FROM
V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d, V$INSTANCE i WHERE tp.PLATFORM_NAME =
d.PLATFORM_NAME and d.DB_UNIQUE_NAME = i.INSTANCE_NAME;
2.源数据库新建测试表空间和用户
create tablespace ocp datafile 'F:\app\Administrator\oradata\orcl\ocp01.dbf'
size 100m autoextend on next 10m maxsize unlimited extent management local
autoallocate segment space management auto;
create user test identified by password default tablespace ocp temporary
tablespace temp;
grant dba to test;
conn test/password@orcl
create table t1 ( sid int not null primary key, sname varchar2(10) );
insert into t1 values(101,'wind'); insert into t1 values(102,'snow'); insert
into t1 values(103,'apple');
commit;
select table_name from dba_tables where tablespace_name='OCP';
3.源数据库检测是否自包含
conn sys/password@orcl as sysdba --需要sys账户
exec dbms_tts.transport_set_check('OCP', TRUE , TRUE);
SELECT * FROM TRANSPORT_SET_VIOLATIONS;
4.生成可传输表空间集
4.1将表空间置为READ-ONLY
alter tablespace ocp read only;
4.2 使用Data Dump导出表空间集元数据
/** DIRECTORY 指定转储文件和日志文件所在的目录 DIRECTORY=directory_object
Directory_object用于指定目录对象名称.需要注意, 目录对象是使用CREATE
DIRECTORY语句建立的对象,而不是OS目录 Expdp scott/tiger DIRECTORY=dump
DUMPFILE=a.dump */
connect / as sysdba
create directory dump as 'f:\dump'; --必须创建此目录 f:\dump
drop directory dump;--删除
exit;
--在 cmd 中直接 执行此命令
expdp system/password@orcl directory=dump dumpfile=ocp.dmp
transport_tablespaces=ocp
4.3 将生成的文件和表空间的数据文件拷贝到指定目录
copy f:\dump\* f:\backup\
copy F:\app\Administrator\oradata\orcl\ocp01.dbf f:\backup\
4.4 设置表空间为read write
alter tablespace ocp read write;
5.目标数据库
5.1 新建目录
sqlplus / as sysdba
create directory dump as 'e:\dump' --必须创建此目录 e:\dump
exit;
5.2 从源数据库拷贝数据
copy \\192.168.2.188\f$\backup\* e:\dump\
copy e:\dump\ocp01.dbf E:\app\Administrator\oradata\orcl\ocp01.dbf
5.3 检查字符集
select * from nls_database_parameters where parameter='NLS_CHARACTERSET';
5.4 导入元数据:由于目标数据库上没有用户test 因此
remap_schema=test:system迁入了system方案
impdp system/password@orcl directory=dump dumpfile=ocp.dmp
transport_datafiles=E:\app\Administrator\oradata\orcl\ocp01.dbf
remap_schema=test:system
