Oracle的数据库快速复制 (2)

  总算回来了。今天讲述数据库快速复制第二章。

一：首先准备一台服务器A，里面安装了callcenter数据库

二：再准备第二台服务器B，里面安装了aaa数据库

三：目的，将A的callcenter数据库复制到服务器B去，使得服务器B启动oracle就可以启动callcenter数据库跟aaa数据库。

方法如下：

  一：进入到数据库服务器A

[root@learnin9_callcenter oradata]# pwd
/var/oracle/app/oracle/oradata

[root@learnin9_callcenter oradata]# ls

callcenter

[root@learnin9_callcenter oradata]# tar cvzf oradata.callcenter.tar.gz ./callcenter            (将callcenter目录打包)

  二：进入到数据库服务器A

[root@learnin9_callcenter admin]# pwd

[root@learnin9_callcenter admin]# ls

callcenter

[root@learnin9_callcenter oradata]# tar cvzf admin.callcenter.tar.gz ./callcenter            (将callcenter目录打包)

 

  三：注意打包的文件所放的各自目录

将以上两个压缩的文件oradata.callcenter.tar.gz admin.callcenter.tar.gz SCP到数据库服务器B的各自目录。然后tar -xvzf 解压缩 (这些不再烦述)

 

  四：修改oracle 8i的监听文件

[root@learnin9_callcenter admin]# pwd

 /var/oracle/app/oracle/product/8.1.7/network/admin

[root@learnin9_callcenter admin]#vi listener.ora

# LISTENER.ORA Network Configuration File: /var/oracle/app/oracle/product/8.1.7/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
      )
    )
    (DESCRIPTION =
      (PROTOCOL_STACK =
        (PRESENTATION = GIOP)
        (SESSION = RAW)
      )
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 2481))
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /var/oracle/app/oracle/product/8.1.7)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = callcenter)
      (ORACLE_HOME = /var/oracle/app/oracle/product/8.1.7)
      (SID_NAME = callcenter)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = aaa)
      (ORACLE_HOME = /var/oracle/app/oracle/product/8.1.7)
      (SID_NAME = aaa)
    )
  )

 

修改tnsnames文件属性，增加callcenter数据库监听配置

[root@learnin9_callcenter admin]#vi tnsnames.ora

CALLCENTER.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = callcenter)
    )
  )

AAA.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = aaa)
    )
  )

INST1_HTTP.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = SHARED)
      (SERVICE_NAME = aaa)
      (PRESENTATION = http://admin)
    )
  )

EXTPROC_CONNECTION_DATA.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

 

五：修改完毕后，然后lsnrctl start，不过要注意先stop哦，然后再start

六：最为重要的一点要记住，启动这两个数据库之前，一定要先去这个目录看看文件

    [root@learnin9_callcenter dbs]# pwd

    /var/oracle/product/8.1.7/dbs

    [root@learnin9_callcenter dbs]# ls

    [root@learnin9_callcenter dbs]# ls -al
