表空间传输

方法介绍:

实现表空间的传输的条件:操作系统和数据库版本最好一致。

表空间传输的速度就是复制文件的速度。

表空间类的数据对象不可以跨越表空间。

 

要求：

表空间中的对象不能与其他表空间中的对象有关联关系。

 

环境说明:               

源头:机器A 表空间:TEST_DB

目标:机器B 表空间:TEST_DB

 

1 测试表空间是否可以传输。                                                                                                                                            

  execute dbms_tts.transport_set_check('TEST_DB', true);                                                                                                       

  若报过程dbms_tts.transport_set_check不存在,                                                                                                                        

  则用sys的数据库用户执行脚本"$ORACLE_HOME/rdbms/admin/dbmsplts.sql"，进行创建。                                                                                         

 

2 select * from transport_set_violations;                                                                                                                            

  SQL> select * from transport_set_violations;                                                                                                                       

  no rows selected                                                                                                                                                   

  --可以进行传输。                                                                                                                                                          

 

3 设置表空间TEST_DB 为只读.                                                                                                                                          

  alter tablespace TEST_DB read only;    

                                                                                                                            

4 表空间导出.                                                                                                                                                        

  exp \'sys/sys@A as sysdba\' transport_tablespace=y tablespaces=TEST_DB file=/home/oracle/test.dmp log=/home/oracle/test.log                                                                                                         

 

5 复制源表空间的数据文件(注意文件要只读)                                                                                                                             

  cp /ora9/oracle/oradata/testdb2/TEST_DB.dbf TEST_DB.DBF                                                                                                      

 

  复制完成后把源表空间设置可读写。                                                                                                                                  

  alter tablespace TEST_DB read write;  

 

6 把导出的dmp文件和数据文件,复制到目标数据库目录下。                                                                                                                  

  scp TEST_DB.DBF and test.dmp                                                                                                                                      

 

7 目标数据库上建立一个和源表空间的相同的表空间,然后建立用户,指定表空间到TEST_DB。                                                                                    

  然后删除目标数据库上建立的表空间TEST_DB。                                                                                                                       

 

8 复制源数据库的数据文件到目标目录下.                                                                                                                                

  cp TEST_DB.DBF /ora9/oracle/oradata/testdb1/TEST_DB.DBF                                                                                                            

 

9 把导出的dmp和数据文件为基础,倒入数据到目标表空间下即可.                                                                                                            

  imp \'sys/szmeiton@B as sysdba\' transport_tablespace=y   tablespaces=TEST_DB file='test.dmp' datafiles='/ora9/oracle/oradata/testdb1/TEST_DB.DBF' tts_owners=test
