Oracle 傳輸表空間-EXP/IMP

Transport_Tablespace-EXP/IMP

通過傳輸表空間(EXP/IMP方式)將192.168.3.199數據庫下，chenjc用戶下的t1表，導入到192.168.3.198數據庫下，chenjc用戶下；

一 查看操作系統版本，數據庫版本

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 創建測試表空間，測試用戶，測試表

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 檢查準備遷移的表空間是否自包含

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

/*無返回記錄，說明符合傳輸表空間條件*/

四 設置準備傳輸的表空間為只讀

SQL> alter tablespace chenjc read only;

Tablespace altered.

五 通過exp工具導出所要傳輸表空間的原數據

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

Export: Release 11.2.0.3.0 - Production on Mon Aug 3 09:40:25 2015

With the Partitioning, OLAP, Data Mining and Real Application Testing options

Export done in ZHS16GBK character set and AL16UTF16 NCHAR character set

Note: table data (rows) will not be exported

About to export transportable tablespace metadata...

/*雙引號+單引號*/

/*

模擬平臺轉換（同一平臺傳輸不需要這步）

SQL> col platform_name for a35

SQL> select * from v$transportable_platform order by platform_id;

RMAN>convert tablespace "TESTSPACE" to platform 'Microsoft Windows IA (32-bit)' format 'd:\TESTSPACE01.DBF'  --這個是轉換的目標地址

*/

六 將數據庫文件和導出的表空間原文件復制到192.168.3.198服務器

[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 目標數據庫創建用戶，指定表空間(目標數據庫不能有和將要傳輸表空間同名的表空間)

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

User created.

SQL> grant connect,resource,dba to chenjc;

Grant succeeded.

八 通過imp工具導入表空間

[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

Import: Release 11.2.0.3.0 - Production on Mon Aug 3 10:14:15 2015

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

Export file created by EXPORT:V11.02.00 via conventional path

About to import transportable tablespace(s) metadata...

. . importing table                           "T1"

Import terminated successfully without warnings.

/*datafiles必須絕對路徑*/

九 修改用戶默認表空間

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/undotbs01.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
