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 SQL*Plus: Release 10.2.0.1. - Production on Tue Mar :: Copyright (c) , , Oracle. All rights reserved. Connected to an idle instance. SQL> startup
