oracle 启动报错ORA-27125解决方案

脚本：

oracle@edwdb:~> id
uid=(oracle) gid=(oinstall) groups=(oinstall),(dba)
oracle@edwdb:~> su - root
Password: 

由此可知 dba组的ID是1200，然后把1200加入到配置文件中：

/proc/sys/vm/hugetlb_shm_group 

用root用户执行：

echo  > /proc/sys/vm/hugetlb_shm_group

成功：

oracle@edwdb:~> sqlplus / as sysdba
