用rman将Oracle迁移到异机

windows环境

oracle 10.2.0.1

源库：192.168.1.81

目标库：192.168.1.2

 

主要流程：

停止源库->备份->恢复->改数据文件位置->resetlogs打开

 

迁移数据库81 到192.168.1.2上

停81库，设置归档路径，将其启动到归档模式，

以administrator身份启动数据库服务oracleserviceorcl

备份测试
C:\>set oracle_sid=orcl
C:\>rman target /
RMAN> backup current controlfile format '\\192.168.1.2\oradata\81\cf_%U';
 

全备

run {
backup as compressed backupset database
 format '\\192.168.1.2\oradata\81\dbfull_%d_%T_%s';
sql 'alter system archive log current';
}

搜集信息
sqlplus "/as sysdba"

set linesize 130 pagesize 2000
set trimspool on
set echo off
set verify off
set timing off
set feedback off
set head off
set echo off

spool renfile.sql

select 'set newname for datafile '''||name||''' to ''d:\oradata\81\'||  substr(name, instr(name, '\', -1) + 1)||'''; ' cmd  from v$datafile
union all
select 'set newname for tempfile '''||name||''' to ''d:\oradata\81\'||  substr(name, instr(name, '\', -1) + 1)||'''; ' cmd  from v$tempfile;

spool off

创建pfile文件，拷贝到目标位置
create pfile from spfile;

 

修改pfile文件中的路径，注意dump目录、控制文件目录、归档位置目录（最好将需要恢复的归档日志拷贝到此目录 以便恢复）

启动实例到nomount状态，恢复控制文件
set oracle_sid=orcl
rman target /
startup nomount
restore controlfile from 'd:\oradata\81\DBFULL_ORCL_20110111_21';  #控制文件得提前知道放哪了
也就是段句柄=\\192.168.1.2\ORADATA\81\DBFULL_ORCL_20110111_21

 

alter database mount;
catalog start with 'e:\oradata\bak' noprompt;  #备份集的位置指定一下

如果缺少归档日志

sqlplus "/as sysdba"

alter database rename file 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\REDO03.LOG' to 'd:\oradata\81\redo03.dbf';

 

检查控制文件、数据文件、日志文件、临时文件位置是否正确。
