使用RAC的時候，經常有朋友問如何修改IP，10.2的我就不說了，修改方法成熟的很，出了問題也很好解決。

從11.2開始，修改IP方法和以前差不多，但是出了問題，有些人不知道如何處理，這裡介紹一個使用gpnp修復的方法（還可以用重建crs的方法），該方法已經在11.2和12c上都實施成功了。

模擬錯誤：

使用oifcfg故意設定錯誤的內部網際網路段（其他使用oficfg錯誤的修改了IP，後果類似）

[[email protected] ~]# oifcfg -help


Name:
        oifcfg - Oracle Interface Configuration Tool. 


Usage:  oifcfg iflist [-p [-n]]
Shows the available interfaces that you can configure with 'setif' by querying the operating system to find which network interfaces are present on this node.


        where -p displays a heuristic assumption of the interface type (PRIVATE, PUBLIC, or UNKNOWN).
        -n displays the netmask.
        oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>

:<if_type>[,<if_type>...]}[,...]
        oifcfg getif [-node <nodename> | -global] [ -if <if_name>[/<subnet>] [-type <if_type>] ]
        oifcfg delif {{-node <nodename> | -global} [<if_name>[/<subnet>]] [-force] | -force}
        oifcfg [-help]


        <nodename> - name of the host, as known to a communications network
        <if_name>  - name by which the interface is configured in the system
        <subnet>   - subnet address of the interface

        <if_type>  - one or more comma-separated interface types { cluster_interconnect | public | asm}


[[email protected] ~]# 
這裡面尤其要注意，setif中寫入的是subnet，我見過不只一次有人這個寫錯了導致crs不能啟動……
