只从成功在虚拟机安装了双节点RAC后 能全部启动起来 STATE ONLINE. 可每次重启机器后 总是有几个UNKNOWN的,如果手工就能启动.crs_start ora.xxxxx, 或则是crs_start -f xxxxx

如果不报错都能成功启动起来. 然后网上寻找了下,有人说可能是时间同步问题,如果10秒就没有问题. 想下时间同步,可虚拟机做了时间同步机制啊. 当这个10秒钟的差距,在虚拟机上启动系统本来就有些慢,而且同时启动的时候总有先后区别. 估计两个节点之间因为启动资源快慢程度而导致10秒以上超时.

那么如果一个个节点启动会如何呢?

先启动节点1的机器

[Oracle@node1 ~]$ cd $DBSRCIPTHOME
[oracle@node1 dbsrcipt]$ sh crs_stat_unknow.sh

--结果节点1的 ONS VIP ASM1都起来了,而其他的正在启动中,可以看到VIP2已经挂在节点1上

[oracle@node1 dbsrcipt]$ sh crs_stat_unknow.sh      

--在过几分钟看看,发现节点1的服务全部起来了,GSD和LSNR并没有同时启动的UNKNOWS状态
