前几天在虚拟机上面安装了Oracle rac，今天把节点启动起来之后发现rac工作异常 [oracle@node1 bin]$ ./crs_stat -t

尝试启动侦听 [oracle@node1 bin]$ ./crs_start ora.node1.LISTENER_NODE1.lsnr
CRS-1028: Dependency analysis failed because of:
'Resource in UNKNOWN state: ora.node1.LISTENER_NODE1.lsnr'

查看CRS状态 [oracle@node1 bin]$ ./crsctl check crs
CSS appears healthy

EVM appears healthy
查看CSS状态 [oracle@node1 bin]$ ./crsctl check css

首先停止node1上面的nodeapps
然后启动node1上面的nodeapps [oracle@node1 bin]$ ./srvctl start nodeapps -n node1
[oracle@node1 bin]$ ./crs_stat -t

再重启所有资源 [oracle@node1 bin]$./crsctl stop resources
[oracle@node1 bin]$ ./crsctl start resources
然后在node2上面执行同样的操作，最后发现资源都启动起来了 [oracle@node1 bin]$ ./crs_stat -t

在执行一下 [oracle@node1 bin]$ ./crs_stat -l
所有状态都是online了，OK！
如果还有某个资源没有启动起来，手动执行 [oracle@node1 bin]$ ./crs_start ora.orcl.orcl1.inst(资源名称)
