Oracle 传输表空间-EXP/IMP

Transport_Tablespace-EXP/IMP

 

通过传输表空间(EXP/IMP方式)将192.168.3.199数据库下，chenjc用户下的t1表，导入到192.168.3.198数据库下，chenjc用户下；

 

一 查看操作系统版本，数据库版本

192.168.3.199

[oracle@ogg1 ~]$ cat /etc/issue

Oracle Linux Server release 6.3

 

SQL> select * from v$version where rownum<=2;

BANNER

--------------------------------------------------------------------------------

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

PL/SQL Release 11.2.0.3.0 - Production

 

192.168.3.198

[oracle@ogg2 orcl]$ cat /etc/issue

Oracle Linux Server release 6.3

 

SQL> select * from v$version where rownum<=2;

BANNER

--------------------------------------------------------------------------------

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

PL/SQL Release 11.2.0.3.0 - Production

 

 

二 创建测试表空间，测试用户，测试表

192.168.3.199

 

SQL> create tablespace chenjc datafile '/u01/app/oracle/oradata/orcl/chenjc01.dbf' size 30m autoextend on;

Tablespace created.

 

SQL> create user chenjc identified by chenjc default tablespace chenjc;

User created.

 

SQL> grant connect,resource,dba to chenjc;

Grant succeeded.

 

SQL> conn chenjc/chenjc

Connected.

 

SQL> create table t1 as select level id,sysdate as t_date from dual connect by level<=100000;

Table created.

 

三 检查准备迁移的表空间是否自包含

SQL> conn /as sysdba

Connected.

 

SQL> execute dbms_tts.transport_set_check(ts_list=>'CHENJC',incl_constraints=>TRUE);

PL/SQL procedure successfully completed.

 

SQL> select * from transport_set_violations;

no rows selected

 

四 设置准备传输的表空间为只读

SQL> alter tablespace chenjc read only;

Tablespace altered.

 

五 通过exp工具导出所要传输表空间的原数据

[oracle@ogg1 ~]$ exp "'sys/oracle as sysdba'" file=chenjc.dmp log=chenjc.log transport_tablespace=y tablespaces=chenjc

Export terminated successfully without warnings.

 

 

六 将数据库文件和导出的表空间原文件复制到192.168.3.198服务器

[oracle@ogg1 ~]$ scp chenjc.dmp 192.168.3.198:/home/oracle/

[oracle@ogg1 ~]$ scp /u01/app/oracle/oradata/orcl/chenjc01.dbf 192.168.3.198:/home/oracle/

 

192.168.3.198

[oracle@ogg2 ~]$ mv chenjc* /u01/app/oracle/oradata/orcl/

[oracle@ogg2 ~]$ cd /u01/app/oracle/oradata/orcl/

[oracle@ogg2 orcl]$ ll -rth

......

-rw-r--r-- 1 oracle oinstall  16K Aug  3 09:43 chenjc.dmp

-rw-r----- 1 oracle oinstall  31M Aug  3 09:44 chenjc01.dbf

......

 

七 目标数据库创建用户，指定表空间(目标数据库不能有和将要传输表空间同名的表空间)

SQL> create user chenjc identified by chenjc default tablespace users;

User created.

 

SQL> grant connect,resource,dba to chenjc;

Grant succeeded.

 

八 通过imp工具导入表空间

[oracle@ogg2 orcl]$ imp "'sys/oracle as sysdba'" file=chenjc.dmp log=chenjc.log

tablespaces=chenjc datafiles='/u01/app/oracle/oradata/orcl/chenjc01.dbf' transport_tablespace=y

九 修改用户默认表空间

SQL> alter user chenjc default tablespace chenjc;

User altered.

 

十 查看

SQL> select name from v$dbfile;

NAME

--------------------------------------------------------------------------------

/u01/app/oracle/oradata/orcl/system.dbf

/u01/app/oracle/oradata/orcl/sysaux.dbf

/u01/app/oracle/oradata/orcl/user01.dbf

/u01/app/oracle/oradata/orcl/ggm01.dbf

/u01/app/oracle/oradata/orcl/chenjc01.dbf

 

6 rows selected.

 

SQL> conn chenjc/chenjc

SQL> select id,to_char(t_date,'yyyy-mm-dd hh34:mi:ss') from t1 where rownum<=3;

 

        ID TO_CHAR(T_DATE,'YYY
