Vmware 下Oracle RAC搬家
最近虚拟机下的Oracle 10g RAC搬家，搬家完毕之后，Oracle 集群resource之VIP无法正常启动，收到了CRS-0233: Resource or relatives are currently involved with another operation 错误提示。为为啥呢，原来啊，搬家了地址发生变化了，你得使用你家里的新地址阿....
1、环境描述
Oracle 10g RAC + Suse 10
注，将RAC虚拟机搬家之后，通常情况下我们在添加虚拟机时选择复制(移动这个没试过，不知道是否会有问题)
其次，由于选择了复制，虚拟机要生成一个新的UUID(UUID是指在一台机器上生成的数字，它保证对在同一虚拟环境中的机器唯一性)。
同时MAC地址以及网络接口名也会发生相应的变化(首次启动虚拟机原来的eth0以及eth1不可用)，通常情况下需要对此修改。
不同的Linux系统对新网络接口有不同的处理方法。Oracle Linux以及RedHat可以直接把原来的删除然后将新的网络接口名重命名为原来的。
2、CRS-1006/CRS-0215/CRS-0233错误

3、分析故障
#查看节点bo2dbp主机上的ip地址
oracle@bo2dbp:~> ifconfig #当前系统的网络接口名为eth2, eth5
eth2 Link encap:Ethernet HWaddr 00:0C:29:4A:66:28
inet addr:192.168.7.51 Bcast:192.168.7.255 Mask:255.255.255.0

oracle@bo2dbp:~> oifcfg iflist

oracle@bo2dbp:~> oifcfg getif -global #此处发现网络接口名与实际的网卡名不一致

#从上面的情况来看，各个节点的网络接口名不一致，同时网络集群层的配置信息使用了原来的接口名，应当对其更新
#为了统一网络接口名，下面将其使用统一的名字为bond1, bond2
4、解决故障
#将网卡统一重命名，方法参照:http://blog.csdn.net/robinson_0612/article/details/8131771

oracle@bo2dbs:~> oifcfg iflist

#下面的查询中集群层的public与cluster_interconnect还是之前的配置信息
#应该需要改成一致，此处我们先不改，看看会出现什么错误
oracle@bo2dbp:~> oifcfg getif -global

5、小结
a、对于RAC环境下虚拟机的迁移之后，首选需要更改各个虚拟机配置文件中所有磁盘的路径(local disk,asmdisk,ocr,votingdisk)
b、添加虚拟机方式使用了复制方式(移动方式不确定)后将导致网卡发生变化，主要是保证MAC地址唯一
c、需要对网络重新进行配置，如果希望使用原来的网络接口名，则重命名或命令行下修改相关配置文件使得保留原有网卡名
d、如果使用了X window方式修改网络配置，应注意hosts文件是否发生相应的修改
e、如果使用了新的网络接口名或者新的IP地址，应该重新配置集群网络层
f、同时也需要将新网络接口名或者新的IP地址更新的OCR
g、最后一句，从日志来分析与解决问题是源头，是快速定位问题的最佳途径
