YoucanalsouseRMANtotransportanentiredatabasetoadifferentplatformsolongasthetwoplatformshavethesameendianformat具体过程如下:一convert前提条件1检查两平


You can also use RMAN to transport an entire database to a different platform so long as the two platforms have the same endian format


具体过程如下:


一 convert前提条件

1 检查两平台是否有相同的字节顺序


linux 平台如下:

SQL> select platform_name,endian_format from v$transportable_platform where platform_id=(select platform_id from v$database);

PLATFORM_NAME ENDIAN_FORMAT

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

Linux x86 64-bit Little


windows 平台如下:

SQL> select platform_name,endian_format from v$transportable_platform where plat

form_id=(select platform_id from v$database);


PLATFORM_NAME ENDIAN_FORMAT

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

Microsoft Windows x86 64-bit Little




2 检查数据库是否支持整体convert (需要在sqlplus下开启serveroutput)

由于本次convert a database是从‘Linux x86 64-bit’ --->‘Microsoft Windows x86 64-bit’所以有如下:


SQL> set serveroutput on

SQL> DECLARE

2 db_ready BOOLEAN;

3 BEGIN

4 db_ready :=

5 DBMS_TDB.CHECK_DB('Microsoft Windows x86 64-bit',DBMS_TDB.SKIP_NONE);

6 END;

7 /


注意SKIP_NONE (or 0), 表示检测所有表空间


PL/SQL procedure successfully completed.

检查是否出现警告信息,,如果没有出现警告信息则表示可以转换整个数据库。


如下则表示不能转换整个数据库

SQL> DECLARE

2 db_ready BOOLEAN;

3 BEGIN

4 db_ready :=

5 DBMS_TDB.CHECK_DB('HP-UX (64-bit)',DBMS_TDB.SKIP_READONLY);

6 END;

7 /

The specified target platform name 'HP-UX (64-bit)' is invalid or the target

platform is not transportable.


PL/SQL procedure successfully completed.


3 确定两平台有相同的数据库版本

linux 平台如下:

SQL> select * from v$version;


BANNER

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

Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production

PL/SQL Release 11.2.0.2.0 - Production

CORE 11.2.0.2.0 Production

TNS for Linux: Version 11.2.0.2.0 - Production

NLSRTL Version 11.2.0.2.0 - Production


windows平台如下:

SQL> select * from v$version;


BANNER

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


Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production

PL/SQL Release 11.2.0.2.0 - Production

CORE 11.2.0.2.0 Production

TNS for 64-bit Windows: Version 11.2.0.2.0 - Production

NLSRTL Version 11.2.0.2.0 - Production


二 操作步骤

1 以sysdba连接数据库

[oracle@source ~]$ sqlplus / as sysdba


SQL*Plus: Release 11.2.0.2.0 Production on Fri Nov 15 19:28:45 2013


Copyright (c) 1982, 2010, Oracle. All rights reserved.


Connected to an idle instance.


2 以只读方式打开数据库


SQL> startup mount

ORACLE instance started.


Total System Global Area 1252663296 bytes

Fixed Size 2226072 bytes

Variable Size 973080680 bytes

Database Buffers 268435456 bytes

Redo Buffers 8921088 bytes

Database mounted.

SQL> alter database open read only;


Database altered.

SQL> select open_mode from v$database;


OPEN_MODE

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

READ ONLY


3 用rman连接到源数据库作为target

QL> host;

[oracle@source ~]$ rman target /


Recovery Manager: Release 11.2.0.2.0 - Production on Fri Nov 15 19:46:16 2013

connected to target database: CRM (DBID=3599153036)


4 转换数据库

RMAN> CONVERT DATABASE NEW DATABASE 'newdb'

TRANSPORT SCRIPT '/backup/convertdb/transportscript.sql'

TO PLATFORM 'Microsoft Windows x86 64-bit'

DB_FILE_NAME_CONVERT '/oracle/CRM/' '/backup/convertdb';


过程如下:


RMAN> CONVERT DATABASE NEW DATABASE 'newdb'

2> TRANSPORT SCRIPT '/backup/convertdb/transportscript.sql'

3> TO PLATFORM 'Microsoft Windows x86 64-bit'

4> DB_FILE_NAME_CONVERT '/oracle/CRM/' '/backup/convertdb';

Edit init.ora file /oracle/app/db1/dbs/init_00op1uot_1_0.ora. This PFILE will be used to create the database on the target platform

Run SQL script /backup/convertdb/transportscript.sql on the target platform to create database

To recompile all PL/SQL modules, run utlirp.sql and utlrp.sql on the target platform

To change the internal database identifier, use DBNEWID Utility

Finished conversion at source at 15-NOV-13

注意:红色部分为要拷贝到目标平台的文件

6 拷贝转换后的数据文件,参数文件,transportscript.sql 到目标平台


7 更改参数文件和transportscript.sql的内容
