oracle下convert a database

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

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';

Starting conversion at source at 15-NOV-13

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=131 device type=DISK

Directory SYS.ORACLE_OCM_CONFIG_DIR found in the database

Directory SYS.DATA_PUMP_DIR found in the database

Directory SYS.XMLDIR found in the database

Directory SYS.DUMP found in the database

Directory SYS.TSPITR_DIROBJ_DPDIR found in the database

User SYS with SYSDBA and SYSOPER privilege found in password file
