CRS-4046: Invalid Oracle Clusterware configuration.

适用范围

操作系统版本:7.6

数据库版本：11.2.0.4

问题概述

安装完了grid软件之后，集群无法启动。查看报错信息

CRS-4046: Invalid Oracle Clusterware configuration.
CRS-4000: Command Status

根据报错信息提示，可以看出集群配置无效。

问题原因

查看root.sh执行脚本的输出日志发现了相同的报错信息，root.sh没有执行完成，集群配置中与原环境有冲突，导致集群配置失败，多次执行安装脚本，就容易遇到这个问题。

解决方案

使用./rootcrs.pl脚本工具对集群进行反配置。把残留的配置信息清除了之后，重新执行root.sh脚本对集群进行配置。

[grid@rac11g01 ~]$ cd $ORACLE_HOME/crs/install
执行脚本
./rootcrs.pl -deconfig -force -verbose

-deconfig: 表示进行集群配置的反配置（Deconfiguration）操作，这个操作是为了卸载集群配置，使数据库集群从节点上移除，反配置是在移除Oracle集群环境之前的必要步骤。-force是强制进行反配置操作，忽略过程中会提示的报错信息。-verbose会将执行命令的详细信息输出出来。

在执行脚本之前，需要确保自己操作系统上之后安装了，perl-devel以及perl-Env依赖包，如果没有的话，执行脚本会报以下的错误信息

Can't locate Env.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . .) at crsconfig_lib.pm line 703.
BEGIN failed--compilation aborted at crsconfig_lib.pm line 703.
Compilation failed in require at ./rootcrs.pl line 305.
BEGIN failed--compilation aborted at ./rootcrs.pl line 305.

执行脚本之后，看到了以下输出信息如下：

Using configuration parameter file: ./crsconfig_params

日志中提示了需要kill ohasd进程或者是重启机器，反配置执行完成。

重启了机器之后，重新执行root.sh日志信息如下：
