10gRAC系列之四-10gRAC的网络设置

在Oracle10g RAC的安装过程中,网络的设置需要谨慎,也极其重要。
以下将我的Oracle10g RAC环境的网络配置列举一下,供参考。

1.hosts文件的设置
由于RAC要设置多个地址,所以需要准备好网络环境,我的hosts文件设置如下:

#

# Internet host table
#
127.0.0.1       localhost      
172.16.19.11    db210-rac1          db210-rac1.hurray.com.cn     loghost
172.16.19.211   db210-rac1vip       db210-rac1vip.hurray.com.cn
192.168.18.11   db210-rac1priv      db210-rac1priv.hurray.com.cn
192.168.19.11   db210-rac1hb        db210-rac1hb.hurray.com.cn


172.16.19.12    db210-rac2          db210-rac2.hurray.com.cn      
172.16.19.212   db210-rac2vip       db210-rac2vip.hurray.com.cn
192.168.18.12   db210-rac2priv      db210-rac2priv.hurray.com.cn
192.168.19.12   db210-rac2hb        db210-rac2hb.hurray.com.cn

2.监听器的配置
我的监听器文件配置如下:


bash-2.05$ cat listener.ora
# listener.ora.db210-rac1 Network Configuration File: /opt/oracle/product/10.2.0/db/network/admin/listener.ora.db210-rac1
# Generated by Oracle configuration tools.


LISTENER_DB210-RAC1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521)(IP = FIRST))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.19.11)(PORT = 1521)(IP = FIRST))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
    )
  )


3.tnsnames.ora文件配置
网络服务名等配置如下:

bash-2.05$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /opt/oracle/product/10.2.0/db/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.


EYGLE2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = eygle)
      (INSTANCE_NAME = eygle2)
    )
  )


EYGLE1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = eygle)
      (INSTANCE_NAME = eygle1)
    )
  )


EYGLE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = eygle)
      (FAILOVER_MODE =
        (TYPE = SELECT)
        (METHOD = BASIC)
        (RETRIES = 180)
        (DELAY = 5)
      )
    )
  )


LISTENERS_EYGLE =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521))
  )

这就是主要的一些配置文件,其中,Oracle的相关配置文件都是自动生成的,VIP可以实现故障时的自动切换。

db210-rac1hb ,db210-rac2hb 是干嘛用的啊? 我们就没有这个

这个是心跳地址,不设ip也是可以的,但是网卡肯定是有的。

那和db210-rac1priv,db210-rac2priv有什么区别

对啊, 这个心跳地址和private网有什么区别?!
我一直都没有设置过这个
