根据网上说，为$GRID_HOME/bin/oracle权限问题引起：
[grid@rac1 ~]$ cd /u01/grid11g/bin/

修改权限：

[grid@rac1 bin]$ ls -lhrt oracle

ORACLE_HOME目录下文件权限有问题，更改权限：
[oracle@rac1 oracle]$ cd ..
[oracle@rac1 u01]$ chown oracle:oinstall -R oracle
重启服务器：
[root@rac1 u01]# reboot
[root@rac1 u01]# ps -ef|grep ora

奇怪，实例依然无法重启，sqlplus 连接不再报12547，尝试启动实例，报错如下：
[oracle@rac1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Dec 16 17:48:12 2014

ORA-17503: ksfdopn:2 Failed to open file +DATA/RACDB/spfileRACDB.ora
SQL> exit
Disconnected
根据网上说，为$GRID_HOME/bin/oracle权限问题引起：
[grid@rac1 ~]$ cd /u01/grid11g/bin/
[grid@rac1 bin]$ ls -lhrt orac
ls: orac: No such file or directory
[grid@rac1 bin]$ ls -lhrt ora
ls: ora: No such file or directory
[grid@rac1 bin]$ pwd
/u01/grid11g/bin
[grid@rac1 bin]$ ls -lhrt oracle
-rwxr-x--x 1 grid oinstall 195M Aug 20 2013 oracle
[grid@rac1 bin]$ pwd
/u01/grid11g/bin
修改权限：
[grid@rac1 bin]$ chmod 6751 oracle
[grid@rac1 bin]$ ls -lhrt oracle
-rwsr-s--x 1 grid oinstall 195M Aug 20 2013 oracle
[grid@rac1 bin]$ exit
logout
[root@rac1 oracleasm]# su - oracle
[oracle@rac1 ~]$ exit
logout
[root@rac1 oracleasm]# su - grid
正常启动实例：
[grid@rac1 ~]$ srvctl start instance -d racdb -i RACDB1
[grid@rac1 ~]$
[grid@rac1 ~]$ crs_stat -t -v
