题记: 可以使用rman 的duplicate命令直接把asm存储的数据库复制到文件管理的系统,本文就是基于这样的情况。。。。。

  1. duplicate体系结构

搞点英语出来吧,英语不好的哥们就好好翻译翻译吧,这段英语是必须看懂的。。。。

You can duplicate a source database to a destination database, which can be on the same or different computers. The database instance associated with the duplicate database is called the auxiliary instance. All duplication techniques require a connection to the auxiliary instance. The diagram shows you the following techniques for database duplication:

  • From an active database, connected to the target and auxiliary instances
  • From backup, connected to the target and auxiliary instances
  • From backup, connected to the auxiliary instance, not connected to the target, but with recovery catalog connection
  • From backup, connected to the auxiliary instance, not connected to the target and the recovery catalog

Choosing a technique to duplicate your database—always with connection to the auxiliary instance:

采用DUPLICATE 把asm数据库复制到文件系统

简单点就是 ①基于备份 ,而基于备份又分为3种情况 ②基于活动数据库

  1. 本次实验简介

本次实验就是基于备份,但是不连接到目标数据库,也不连接到恢复目录。

When you duplicate a database without a target database connection and without a recovery catalog, RMAN uses a BACKUP LOCATION where all necessary backups and copies reside.

The diagram illustrates backup-based duplication without connections to the target or to the recovery catalog database instance. A disk backup location containing all the backups or copies for duplication must be available to the destination host.

  1. 本次实验原理图

采用DUPLICATE 把asm数据库复制到文件系统

  1. 环境及搭建要求

环境:

  • source host :192.168.59.130 sid:orclasm database:11gR2 文件系统:ASM系统
  • Destination host :192.168.59.135 sid:orcl database:11gR2

注意事项说明:

  • 这里列出source database主要是为了备份
  • 源数据库和辅助数据库的几种不同名称:source/target database ---->>>>>----- (destination host)/duplicate database (auxiliary instance)
  • 源数据库是ASM管理的,目标数据库是文件管理系统的
  • 源数据库开启了数据库闪回,块改变跟踪,属于归档模式

  1. 对辅助数据库的要求

辅助数据库应该提前安装好数据库,配置好环境变量。。。。。

辅助数据库的环境变量配置:

. ~/.bashrc

采用DUPLICATE 把asm数据库复制到文件系统

  1. 连接到auxiliary instance并复制数据库

先准备run块,在source database上:

select 'set newname for datafile '||a.FILE#||' to "'||a.NAME||'";' from v$datafile a

union all

select 'set newname for tempfile '||a.FILE#||' to "'||a.NAME||'";' from v$tempfile a;

采用DUPLICATE 把asm数据库复制到文件系统

修改一下文件名,加入logfile,注意controlfile已经在pfile中指定了:

RUN{

set newname for datafile 1 to "/u01/app/oracle/oradata/system.dbf";

set newname for datafile 2 to "/u01/app/oracle/oradata/sysaux.dbf";

set newname for datafile 3 to "/u01/app/oracle/oradata/undotbs1.dbf";

set newname for datafile 4 to "/u01/app/oracle/oradata/users.dbf";

set newname for datafile 5 to "/u01/app/oracle/oradata/example.dbf";

set newname for datafile 6 to "/u01/app/oracle/oradata/undotbs2.dbf";

set newname for datafile 7 to "/u01/app/oracle/oradata/tbs_rc.dbf";

set newname for datafile 8 to "/u01/app/oracle/oradata/ts_lhr.dbf";

set newname for tempfile 1 to '/u01/app/oracle/oradata/TEMP01.DBF';

duplicate target database to orcl backup location '/home/oracle/ora_bk' nofilenamecheck

LOGFILE

'/u01/app/oracle/oradata/redo01.log' SIZE 20M,

'/u01/app/oracle/oradata/redo02.log' SIZE 20M,

'/u01/app/oracle/oradata/redo03.log' SIZE 20M;

}

在这里也可以多分配几个通道,加快恢复速度:

RUN{

ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;

ALLOCATE AUXILIARY CHANNEL aux2 DEVICE TYPE DISK;

set newname for datafile 1 to "/u01/app/oracle/oradata/system01.dbf";

set newname for datafile 2 to "/u01/app/oracle/oradata/sysaux01.dbf";

set newname for datafile 3 to "/u01/app/oracle/oradata/undotbs1.dbf";

set newname for datafile 4 to "/u01/app/oracle/oradata/users01.dbf";

set newname for datafile 5 to "/u01/app/oracle/oradata/example.dbf";

set newname for datafile 6 to "/u01/app/oracle/oradata/undotbs2.dbf";

set newname for datafile 7 to "/u01/app/oracle/oradata/tbs_rc.dbf";

set newname for datafile 8 to "/u01/app/oracle/oradata/ts_lhr.dbf";

set newname for tempfile 1 to '/u01/app/oracle/oradata/temp01.DBF';

duplicate target database to orcl backup location '/home/oracle/ora_bk' nofilenamecheck

LOGFILE

'/u01/app/oracle/oradata/redo01.log' SIZE 20M,

'/u01/app/oracle/oradata/redo02.log' SIZE 20M,

'/u01/app/oracle/oradata/redo03.log' SIZE 20M;

}

恢复的时候就是2个通道恢复:
