使用RMAN的DUPLICATE克隆Oracle10g R2 数据库


这里我已经有一个安装好的数据库，版本是：10g R2  主机名称：dg1.andylhz.com 实例名dg，另外一台数据库主机，安装Oracle软件和第一台数据库的安装环境一样，但没有安装数据库。主机名称：dg2.andylhz.com，实例名，dgc

1、将dg1的系统参数文件，监听文件，密码文件，拷贝到dg2的相应位置。

编辑初始化参数文件initdg.ora 将文件中的dg全部替换成dgc 保存并重命名为：initdgc.ora

如下：

[oracle@dg2 dbs]$ more /u01/app/oracle/10g/dbs/initdgc.ora

dgc.__db_cache_size=67108864

dgc.__java_pool_size=4194304

dgc.__large_pool_size=4194304

dgc.__shared_pool_size=88080384

dgc.__streams_pool_size=0

*.audit_file_dest='/u01/app/oracle/admin/dgc/adump'

*.background_dump_dest='/u01/app/oracle/admin/dgc/bdump'

*.compatible='10.2.0.1.0'

*.control_files='/u01/app/oracle/oradata/dgc/control01.ctl','/u01/app/oracle/oradata/dgc/control02.ctl','/u01/app/oracle/oradata/dgc

/control03.ctl'

*.core_dump_dest='/u01/app/oracle/admin/dgc/cdump'

*.db_block_size=8192

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_name='dgc'

*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.dispatchers='(PROTOCOL=TCP) (SERVICE=dgXDB)'

*.job_queue_processes=10

*.log_archive_format='%t_%s_%r.dbf'

*.open_cursors=300

*.pga_aggregate_target=16777216

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=167772160

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/u01/app/oracle/admin/dgc/udump'

*.db_file_name_convert='/u01/app/oracle/oradata/dg','/u01/app/oracle/oradata/dgc'

*.log_file_name_convert='/u01/app/oracle/oradata/dg','/u01/app/oracle/oradata/dgc'   

#红色字体的参数需要设置好，否则在执行duplicate命令的时候报告辅助数据库和目标数据库的文件命冲突。

 

2、将密码文件重命名：mv orapwdg  orapwdgc

3、将监听文件中的主机名改成 dg2.andylhz.com 实例名改成dgc

如下：

#注意，这里的监听文件需要使用静态注册，否则客户端连接辅助数据库连接不上。所以不能使用动态链接方式。

#listener.ora

[oracle@dg2 admin]$ more /u01/app/oracle/10g/network/admin/listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/10g/network/admin/listener.ora

# Generated by Oracle configuration tools.

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /u01/app/oracle/10g)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = dgc)

      (ORACLE_HOME = /u01/app/oracle/10g)

      (SID_NAME = dgc)

  )
