RMAN學習筆記

今天大榕樹羣討論了很久win剪頭linux或者linux→win能否通過備份恢復來遷移，
故貼出當年的RMAN學習筆記以供參考：

一.RMAN本機備份與恢復

二.RMAN同平臺，同目錄，同版本備份與異機恢復

複製備份文件到相同目錄

rman target /

start nomount

restore spfile to "D:\oracle\product\10.2.0\db_1\database\SPFILEE1LOCAL.ORA1" from "d:\backups\FULLBACKUP_E1LOCAL_20100926_2_1";
然後把SPFILEE1LOCAL.ORA1 重命名爲SPFILEE1LOCAL.ORA，並替換原來的同名文件（注意備份）

shutdown immediate

startup nomount

restore controlfile from "d:\backups\FULLBACKUP_E1LOCAL_20100926_2_1";
alter databse mount

restore database

alter database open resetlogs;

三.RMAN同平臺，同目錄，不同版本備份與恢復（10.2.0.3-10.2.0.4）

rman target /

start nomount

restore spfile to "D:\oracle\product\10.2.0\db_1\database\SPFILEE1LOCAL.ORA1" from "d:\backups\FULLBACKUP_E1LOCAL_20100926_2_1";
然後把SPFILEE1LOCAL.ORA1 重命名爲SPFILEE1LOCAL.ORA，並替換原來的同名文件（注意備份）

shutdown immediate

startup nomount

set dbid=3764326251

restore controlfile from "d:\backups\FULLBACKUP_E1LOCAL_20100926_2_1";
alter databse mount

restore database

alter database open resetlogs;

sqlplus / as sysdba

startup upgrade

@?\rdbms\admin\catupgrd.sql

shutdowm immediate

startup

@?\rdbms\admin\utlrp.sql

alter system set compatible='10.2.0.4' scope=spfile;

shutdowm immediate

startup

四.RMAN同平臺，不同目錄，同版本備份與恢復

restore spfile to "D:\oracle\product\10.2.0\db_1\database\SPFILEE1LOCAL.ORA1" from "d:\backups\FULLBACKUP_E1LOCAL_20100926_2_1";
restore controlfile from "/oracle/backup/FULLBACKUP_E1LOCAL_20100926_2_1";
RUN

SET NEWNAME FOR DATAFILE 1 TO '/oracle/u02/oradata/E1Local/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/oracle/u02/oradata/E1Local/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/oracle/u02/oradata/E1Local/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 4 TO '/oracle/u02/oradata/E1Local/users01.dbf';
restore database from tag="full_db_backup";}

五.RMAN不同平臺，同版本備份與恢復

六.RMAN與Dataguard。
