三：问题处理
一头雾水，最后不知道那个操作步骤解决问题，下面记录操作步骤
1.查看mos尝试找到解决方案
根据提示，可能是产品目录表的问题，将产品目录表卸载之后，继续尝试安装，无效
./runInstaller -detachhome ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1/ ORACLE_HOME_NAME=OraDB12Home1
2.怀疑是$ORACLE_HOME/bin/oracle权限问题，修改权限属性无效
3.根据mos，更新节点2OPatch无效
4.修改/u01目录权限
chmod -R 775 /u01
4.将删除的产品目录信息恢复，重新测试，通过
./runInstaller -attachHome ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1/ ORACLE_HOME_NAME=OraDB12Home1
5.应用补丁无报错
