数据库迁移(分享101续集)

          上集主要讲解了oracle本人导入导出功用,本集讲解rman那几个工具。

           Oracle 1一g福睿斯二 使用奥德赛MAN Duplicate复制数据库、通过备份苏醒措施来搬迁数据库。

 

Active database duplicate
作用强大,不需求先把目的数据库举办rman备份,只要指标数据库处于归档方式下即可间接通过网络对数据库进行copy,且copy完成后自行open数据库。那对于大数量尤其是T级其他数据库来说优点10分显眼,复制前不须求开始展览备份,减少了备份和传递备份的时光,同时节约备份空间。上边来展开实际的duplicate操作。

运用场景:

 

 

Oracle 1

           Active database duplicate
功用强大,不需求先把对象数据库进行rman备份,只要指标数据库处于归档形式下即可直接通过互连网对数据库进行copy,且copy完毕后自动open数据库。那对于大数目尤其是T级其他数据库来说优点卓殊显然,复制前不要求实行备份,收缩了备份和传递备份的时间,同时节约备份空间。上面来进行具体的duplicate操作。

行使场景:文件路径壹样,旧库能够使用并且互联网顺遂**

尝试环境:

target db:

ip 192.168.56.1

oracle_sid=test

oracle_version=11.2.0.3

auxiliary db:

ip 192.168.56.2

oracle_sid=test

oracle_version=11.2.0.3

在新库创造参数文件并运行实例到nomount状态

–auxiliary db上执行

[oracle@localhost ~]$ cat initoradu.ora

db_name=test

db_block_size=8192

 

[oracle@localhost ~]$ export ORACLE_SID=test

[oracle@localhost ~]$ sqlplus / as sysdba

二、创立密码文件

–必须维持target DB和auxiliary DB的密码1致。那里自个儿平素把target
db的密码文件复制到auxiliary db对应的目录下一视同仁命名

–target db上执行

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

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必须接纳静态监听,不然报错奇骏MAN-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=test)

    )

  )

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

  test =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.1)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = test)

      (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 = test)

    )

  )

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

  test =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.2)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = test)

      (SERVER = DEDICATED)

    )

  )

  –重启两台机械的监听

  lsnrctl stop

  lsnrctl start

4、开头复制

–在target db上执行

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