某位仁兄新装一套Oracle 11gR2 RAC的过程中，在GI的安装配置阶段遇到了安装目录无法写入的报错，于是他便将$GRID_HOME下所有目录和文件属主改成了grid:oinstall，将$GRID_HOME下所有目录和文件权限改成了757，将$ORACLE_HOME下所有的目录和文件权限改成了757，侥幸过了安装这一关，紧接着麻烦就找上门了：使用srvctl无法启动数据库，症状如下：
$ /oracle/app/oracle/product/11.2.0/db_1/bin/srvctl start database -d shpboss -o open
PRCR-1079 : Failed to start resource ora.shpboss.db
CRS-2503: Resource 'ora.shpboss.db' is in UNKNOWN state and must be stopped first
CRS-2680: Clean of 'ora.shpboss.db' on 'qzp750707b' failed
CRS-5802: Unable to start the agent process <--- 关键在于oracle agent无法启动
---GI的alert.log：$GRID_HOME/log/qzp750707b/alertqzp750707b.log里显示
