10gRAC系列之10gRAC的网络设置_Oracle教程

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，所以需要预备好网络环境，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。 -The End- 原文地址：http://www.eygle.com/archives/2007/01/10grac_netconfig.Html
