本实例测试Oracle 11g使用rman复制数据库。11g的RMAN duplicate 可以通过Active database duplicate和Backup-based duplicate两种方法实现。这里的测试使用的是Backup-based duplicate。

应用场景。基于Active database duplicate参考

1、旧库或网络不可用，但是有备份

实验环境：

target db：

ip 192.168.56.10

oracle_sid=mydb

oracle_version=11.2.0.3

auxiliary db：

ip 192.168.56.150

oracle_sid=oradu

oracle_version=11.2.0.3

1、备份target db

RMAN> backup database include current controlfile plus archivelog delete all input;

2、复制参数文件和创建密码文件

--必须保持target DB和auxiliary DB的密码一致。这里我直接把target db的密码文件复制到auxiliary db对应的目录下

--target db上执行

[oracle@localhost ~]$ cd $ORACLE_HOME/dbs

[oracle@localhost dbs]$ scp orapwmydb oracle@192.168.56.150:/home/oracle

oracle@192.168.56.150's password:

orapwmydb                                    100% 1536    1.5KB/s  00:00   

[oracle@localhost dbs]$ scp initmydb.ora oracle@192.168.56.150:/home/oracle

oracle@192.168.56.150's password:

initmydb.ora                                  100%  193    0.2KB/s  00:00   

3、把旧机器的备份复制到新机器上的对应目录

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/34r0vd8l_1_1 oracle@192.168.56.150:/home/oracle/bak

oracle@192.168.56.150's password:

34r0vd8l_1_1                                  100% 5457KB  5.3MB/s  00:00   

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/35r0vd8m_1_1 oracle@192.168.56.150:/home/oracle/bak

oracle@192.168.56.150's password:

35r0vd8m_1_1                                  100% 1049MB  15.0MB/s  01:10   

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/36r0vdad_1_1 oracle@192.168.56.150:/home/oracle/bak

oracle@192.168.56.150's password:

36r0vdad_1_1                                  100% 9952KB  9.7MB/s  00:00   

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/37r0vdag_1_1 oracle@192.168.56.150:/home/oracle/bak

oracle@192.168.56.150's password:

37r0vdag_1_1                                  100%  10KB  10.0KB/s  00:00   

4、更改密码文件、参数文件的文件名和参数文件中的对应的实例名(实例名不变时不需要执行),

把目录转换参数加入参数文件中(实例名、目录不变时不需要)

本实验中更新实例名为oradu

[oracle@localhost ~]$ mv initmydb.ora initoradu.ora

[oracle@localhost ~]$ mv orapwmydb orapworadu

vi initoradu.ora把所有的旧实例名mydb改为oradu，并加入转换参数

db_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')

log_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')

新建目录

mkdir -p /u01/app/oracle/oradata/oradu/

不改变实例名只需要新建目录

mkdir -p /u01/app/oracle/oradata/mydb/

移动参数文件和密码文件到默认目录中/u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~]$ mv initoradu.ora /u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~]$ mv orapworadu /u01/app/oracle/product/11.2.0/db/dbs/

5、启动到nomount

[oracle@localhost ~]$ export ORACLE_SID=oradu

[oracle@localhost ~]$ sqlplus / as sysdba

6、使用RMAN开始复制
