RAC重启遭遇ORA-01078、ORA-01565、ORA-17503、ORA-12547错误

问题描述：

上周五下班后把测试rac关闭后，今天早上打开报以下错误：

[oracle@rac1 11.2.0]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Mon Jun 5 09:27:09 2017

Connected to an idle instance.

SQL> startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/rac/spfilerac.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/rac/spfilerac.ora
ORA-12547: TNS:lost contact

解决方法：

1、首先通过crsctl stat res -t命令查看集群服务，发现服务正常；

2、查看grid用户下/u01/grid/app/11.2.0/grid/bin/oracle文件权限变为-rwxr-x--x，其正常权限应为-rwsr-s--x（6751），如下：

[grid@rac1 ~]$ cd /u01/grid/app/11.2.0/bin
[grid@rac1 bin]$ ls -lh oracle
-rwxr-x--x 1 grid oinstall 201M Mar 22 09:15 oracle

3、修改权限为6751
[grid@rac1 bin]$ chmod 6751 oracle

4、查看权限修改正确

[grid@rac1 bin]$ ll -h oracle
