本文主要是介绍oracle 4535,CRS-4535: Cannot communicate with Cluster Ready Services，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
问题描述：在vmware workstation 9上搭建oracle 11g rac环境的时候，grid安装完毕，但是在执行crs_stat -t命令验证安装的时候，只能看见自己节点的信息：
我在执行数据库软件安装的时候，发现只能看见rac1的节点，rac2节点看不见

笔者这里安装了2个节点的rac，2个节点都只能看见自身的crs信息，之前的安装步骤都是执行成功的，于是重启2个节点是系统，尝试是否会正常，但想法太单纯了，当我自动重启2个节点的时候，发现最先启动的那个节点能看见crs信息，而另一个后启动的节点则出现错误：
RAC 2 系统先被拉起：

RAC 1在RAC 2节点后启动：

发现重启后，只要是后启动的那个节点，crs就启动不成功，然后查看一下节点的实例状态

发现rac 1节点的crs还是不能启动，此时安装后没有修改过任何东西，为撒rac 1就启动不来了呢？查看rac 1的实例
grid@rac1:~> echo $ORACLE_SID

grid@rac1:~>echo$ORACLE_SID

实例确实是+ASM1，但刚才看见RAC 2上注册了这个实例，怀疑2个节点实例混乱了，临时修改一下rac 1的实例为+ASM2

然后发现rac 1的crs自动拉起来了，执行数据库软件安装，可以看见所有的节点了。
