异构平台表空间迁移--传输表空间

异构平台表空间迁移--传输表空间

源库
主机系统 Solaris Operating System (x86-64)
oracle 11.2.0.1 

目标库
主机系统 redhat linux 32bit
oracle 11.2.0.1

1、源库操作

在源库将要传递的表空间设置为只读
--说明，tts_user用户的默认表空间为tts
alter tablespace tts read only;

在源库导出表空间的元数据：
expdp system/oracle DIRECTORY=DATA_PUMP_DIR DUMPFILE=tts.dmp TRANSPORT_TABLESPACES=tts

拷贝元数据和表空间对应的文件到目标库主机
tts01.dbf --数据文件
tts.dmp   --表空间元数据

2、目标库操作

查询字节序
set pages 1000
COLUMN PLATFORM_NAME FORMAT A36
SSELECT * FROM V$TRANSPORTABLE_PLATFORM ORDER BY PLATFORM_NAME;

PLATFORM_ID PLATFORM_NAME                        ENDIAN_FORMAT
----------- ------------------------------------ --------------
          6 AIX-Based Systems (64-bit)           Big
         16 Apple Mac OS                         Big
         21 Apple Mac OS (x86-64)                Little
         19 HP IA Open VMS                       Little
         15 HP Open VMS                          Little

          1 Solaris[tm] OE (32-bit)              Big
          2 Solaris[tm] OE (64-bit)              Big

20 rows selected.

在目标库数据库，转化数据
export ORACLE_SID=PROD4
rman target /

CONVERT DATAFILE  '/ora11g/scripts/tts01.dbf'
  DB_FILE_NAME_CONVERT='/ora11g/scripts/tts01.dbf','/ora11g/OracleHomes/oradata/prod4/tts01.dbf'
  FROM PLATFORM 'Solaris Operating System (x86-64)';

创建用户及授权
create user tts_user identified by tts_user; 
grant connect,resource to tts_user;

导入目标库数据库
impdp system/oracle dumpfile='tts.dmp' directory=DATA_PUMP_DIR TRANSPORT_DATAFILES='/ora11g/OracleHomes/oradata/prod4/tts01.dbf'

修改表空间模式
alter tablespace TTS read write;

=========================================================================================
部分操作记录

1、在目标库新建一个用户tts_user

SQL> create user tts_user identified by tts_user; 

User created.

SQL> grant connect,resource to tts_user;

Grant succeeded.

SQL> 
SQL> select username,default_tablespace from dba_users;

USERNAME                       DEFAULT_TABLESPACE
------------------------------ ------------------------------
SYS                               SYSTEM
SYSTEM                         SYSTEM
TTS_USER                       USERS
OUTLN                           SYSTEM
APPQOSSYS                    SYSAUX
DBSNMP                          SYSAUX
WMSYS                           SYSAUX
DIP                                 USERS
ORACLE_OCM                   USERS

9 rows selected.

2、在目标库转化数据

[ora11g@ora11g ~]$ echo $ORACLE_SID
PROD4
[ora11g@ora11g ~]$ 
[ora11g@ora11g ~]$ rman target /

Recovery Manager: Release 11.2.0.1.0 - Production on Sun May 10 00:52:20 2015

connected to target database: PROD4 (DBID=1630404751)

RMAN> CONVERT DATAFILE  '/ora11g/scripts/tts01.dbf'
2>   DB_FILE_NAME_CONVERT
3>   '/ora11g/scripts/tts01.dbf','/ora11g/OracleHomes/oradata/prod4/tts01.dbf'
4>   FROM PLATFORM 'Solaris Operating System (x86-64)';

RMAN> 

RMAN> exit

Recovery Manager complete.
[ora11g@ora11g ~]$ ls -l /ora11g/OracleHomes/oradata/prod4/tts01.dbf

[ora11g@ora11g ~]$

3、使用impdp将数据导入目标库

SQL> set lines 200 pages 10000
SQL> select * from dba_directories;

OWNER  DIRECTORY_NAME        DIRECTORY_PATH
------ --------------------- ------------------------------------
SYS    ORACLE_OCM_CONFIG_DIR /ora11g/OracleHomes/db11g/ccr/state
SYS    DATA_PUMP_DIR         /ora11g/OracleHomes/db11g/rdbms/log/

[ora11g@ora11g ~]$ export ORACLE_SID=PROD4
[ora11g@ora11g ~]$ impdp system/oracle dumpfile='tts.dmp' directory=DATA_PUMP_DIR TRANSPORT_DATAFILES='/ora11g/OracleHomes/oradata/prod4/tts01.dbf'
 
Import: Release 11.2.0.1.0 - Production on Sun May 10 00:56:42 2015

[ora11g@ora11g ~]$ 

4、修改表空间为读写模式

SQL> set lines 120 pages 10000
SQL> select tablespace_name,status from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
SYSAUX                         ONLINE
UNDOTBS1                     ONLINE
TEMP                             ONLINE
USERS                           ONLINE
TTS                               READ ONLY


6 rows selected.


SQL> alter tablespace TTS read write;


Tablespace altered.


SQL> select tablespace_name,status from dba_tablespaces;


TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
SYSAUX                         ONLINE
UNDOTBS1                     ONLINE
TEMP                             ONLINE
USERS                           ONLINE
TTS                               ONLINE


6 rows selected.

至此，异构平台表空间迁移完成。
