Oracle 10g RMAN 跨平台迁移

RMAN异构平台迁移


1．实验环境简介
1.1  SOA生产系统

数据库名    comSOA
实例名      Comsoa
DBID        4133565260
数据库版本	Windows 32bit 10.2.R2
数据文件目录	E:\ORASOA\ORADATA\COMSOA\
Pfile	 Initcomsoa.ora

1.2  待恢SOA系统
数据库名    comSOA
实例名      Comsoa
DBID        4133565260
数据库版本	Linux 64it 10.2R2
数据文件目录	/U01/ORADATA/COMSOA/
Pfile	 Initcomsoa.ora

2  备份 
2.1  备份注意事项
  
1. 迁移库只能在同字节顺序平台之间(即ENDIAN_FORMAT相同)且得是ORACLE所支持的平台，可以在V$TRANSPORTABLE_PLATFORM中查看。 
2. 传输前需要将源库置为只读。 
3. 生成的2个脚本文件要仔细根据需要修改。

2.2  源库操作
2.2.1  将库只读，并检查是否支持迁移

一．将库只读，并检查是否支持迁移
SQL> startup mount
SQL> alter database open read only;

2.2.2  检查支持迁移平台
 SQL> select * from v$transportable_platform;
PLATFORM_ID PLATFORM_NAME                      ENDIAN_FORMAT
----------- --------------------------------  --------------
          2 Solaris[tm] OE (64-bit)               Big
          7 Microsoft Windows IA (32-bit)         Little
          10 Linux IA (32-bit)                    Little
          6 AIX-Based Systems (64-bit)            Big
          4 HP-UX IA (64-bit)                     Big
          11 Linux IA (64-bit)                    Little
          15 HP Open VMS                          Little
          8 Microsoft Windows IA (64-bit)         Little
17 rows selected.

2.2.3  利用dbms_tdb 包检查数据库
二．利用dbms_tdb 包检查数据库能否被传输以及列出外部表和DIRECTORY 等无法传输的对象信息，分别在windows平台数据库通过SQLPLUS执行以下两个存储过程

SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 /* db_ready is ignored, but with SERVEROUTPUT set to ON any
5 * conditions preventing transport will be output to console */
6 db_ready := dbms_tdb.check_db('Microsoft Windows IA (32-bit)',
7 dbms_tdb.skip_none);
8 end;
9 /

PL/SQL procedure successfully completed.
 
SQL> declare
2 external boolean;
3 begin
4 /* value of external is ignored, but with SERVEROUTPUT set to ON
5 * dbms_tdb.check_external displays report of external objects
6 * on console */
7 external := dbms_tdb.check_external;
8 end;
9 /

PL/SQL procedure successfully completed.

2.2.4  RMAN  ConvertDB
连接target database 查看数据库打开模式
C:\ Administrator > set oracle_sid=comsoa
C:\ Administrator > sqlplus / as sysdba
SQL> select open_mode from v$database;

OPEN_MODE
----------
READ ONLY

利用RMAN convertDB 转化数据库

C:\ Administrator > rman target /
RMAN>  convert database new database 'comsoa'
2>   transport script 'f:\transdb.sql'
3>   to platform 'Linux IA (64-bit)'
4>   db_file_name_convert 'e:\orasoa\oradata\comsoa\','f:\trans_dir\';
注：
'f:\transdb.sql'：数据库转化脚本生产位置
'Linux IA (64-bit)'：被转化的平台
e:\orasoa\oradata\comsoa\：源数据库数据文件位置
'f:\trans_dir\'：转化后生成新的数据文件位置
启动 convert 于 08-12月-11
使用目标数据库控制文件替代恢复目录
分配的通道: ORA_DISK_1
通道 ORA_DISK_1: sid=318 devtype=DISK
在数据库中找到目录 SYS.WORK_DIR
在数据库中找到目录 SYS.ADMIN_DIR
在数据库中找到目录 SYS.DATA_PUMP_DIR
………
……….
………..
通道 ORA_DISK_1: 数据文件转换完毕, 经过时间: 00:00:01
在目标平台上运行 SQL 脚本 F:\TRANSDB.SQL 以创建数据库
编辑 init.ora 文件 E:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\INIT_00MTMNQN_1_0.ORA。
此 PFILE 将用于在目标平台上创建数据库据
要重新编译所有 PL/SQL 模块, 请在目标平台上运行 utlirp.sql 和 utlrp.sql
要更改内部数据库标识符, 请使用 DBNEWID 实用程序
完成 backup 于 03-12月-11
2.2.5  修改pfile参数文件
修改在E:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\INIT_00MTMNQN_1_0.ORA 生成的参数文件并重新命名为initcomsoa.ora

2.2.6  重建控制文件脚本TRANSDB.SQL

根据linux主机路径修改相应的数据文件目录

注：在此文件中注意Linux目标数据库的路径要保证正确，目录属主权限要正确
2.3  Linux平台主机操作
2.3.1  安装oracle数据库软件,建立相关文件夹 
安装好oracle后根据pfile文件内容来创建相关的目录

$mkdir –p /u01/app/oracle/comsoa/admin/adump
$mkdir –p /u01/app/oracle/comsoa/admin/bdump
$mkdir –p /u01/app/oracle/comsoa/admin/cdump
$mkdir –p /u01/app/oracle/comsoa/admin/udump
$mkdir –p /u01/app/oracle/flash_recovery_area
$mkdir –p /u01/orasoa/archive/comsoa
$mkdir –p /u01/app/oracle/oradata/comsoa/
2.3.2  迁移转化
将在windows环境中生成的文件拷贝到linux主机下包括以下文件

1.	f:\trans_dir\目录下的转化后的所有数据文件，还有幻化脚本TRANSDB.SQL拷贝到/u01/app/oracle/oradata/comsoa/目录下，
2.	将修改后的initcomsoa.ora拷贝到/u01/app/oracle/product/10.2.0/db_1/dbs/目录下
2.3.3	 创建实例comsoa 执行转化脚本
$cd  /u01/app/oracle/oradata/comsoa
[oracle@SOA comsoa]$export ORACLE_SID=comsoa
[oracle@SOA comsoa]$ sqlplus / as sysdba
SQL > @TRANSDB.SQL
SQL脚本执行完成后提示以下信息

2.5	 迁移注意事项
1.	确保源库与目标数据库的字符集一致
2.	数据库32bit迁移到64位后要把无效的数据库对象重新编译，确保正确执行utlrp.sql,utlirp.sql
3.	数据库迁移后，确保应用系统用户可以正确连接，登陆有效
4.	监听要重新配置，检查临时表空间的属主与可用性
5.	迁移完成后要立即进行一次全备份
