[经验分享] Oracle11gR2使用RMAN duplicate复制数据库——active database duplicate

11gR2的RMAN duplicate 个人感觉比10g的先进了很多，10G需要在rman备份的基础上进行复制，使用 RMAN duplicate 创建一个数据完全相同但DBID不同的数据库。而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Active database duplicate，因为Active database duplicate 功能强大，不需要先把目标数据库进行rman备份，只要目标数据库处于归档模式下即可直接通过网络对数据库进行copy，且copy完成后自动open数据库。这对于大数据特别是T级别的数据库来说优点非常明显，复制前不需要进行备份，减少了备份和传送备份的时间，同时节省备份空间。下面来进行具体的duplicate操作。

应用场景：

  1、旧库可以使用并且网络顺畅

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、在新库创建参数文件并启动实例到nomount状态

--auxiliary db上执行

[oracle@localhost ~]$ cat initoradu.ora

db_name=oradu

db_block_size=8192

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/')

--由于这里使用的是不同实例，所以必须添加db_file_name_convert和log_file_name_convert，否则在复制的时候会报错无法创建数据文件，如果是同实例名复制，且两数据目录完全一样的情况下，这两个参数可省略。

--在auxiliary db 上创建新库的数据文件在存放的目录

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

[oracle@localhost ~]$ export ORACLE_SID=oradu

[oracle@localhost ~]$ sqlplus / as sysdba

2、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对应的目录下并重命名

--target db上执行

[oracle@localhost ~]$ scp /u01/app/oracle/product/11.2.0/db/dbs/orapwmydb oracle@192.168.56.150:/u01/app/oracle/product/11.2.0/db/dbs/orapworadu

The authenticity of host '192.168.56.150 (192.168.56.150)' can't be established.

RSA key fingerprint is 58:71:ed:0c:e0:2a:57:68:3e:fe:79:52:8b:72:2e:00.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added '192.168.56.150' (RSA) to the list of known hosts.

oracle@192.168.56.150's password:

orapwmydb                                     100% 1536     1.5KB/s   00:00   

3、配置target db 和auxiliary db的监听

--auxiliary db必须使用静态监听，否则报错RMAN-04006: error from auxiliary database: ORA-12528: TNS:listener: all appropriate instances are blocking new connections

--auxiliary db

vi /u01/app/oracle/product/11.2.0/db/network/admin/listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db)

      (SID_NAME=oradu)

    )

  )

  vi /u01/app/oracle/product/11.2.0/db/network/admin/tnsnames.ora

  mydb =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.10)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = mydb)

      (SERVER = DEDICATED)

    )

  )

--target db

vi /u01/app/oracle/product/11.2.0/db/network/admin/listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db)

      (ORACLE_SID = mydb)

    )

  )

  vi /u01/app/oracle/product/11.2.0/db/network/admin/tnsnames.ora

  oradu =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.150)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = oradu)

      (SERVER = DEDICATED)

    )

  )

  --重启两台机器的监听

  lsnrctl stop

  lsnrctl start

4、开始复制

--在target db上执行

[oracle@localhost ~]$ rman target / auxiliary sys/123456@oradu
