安装数据库后,启动数据库报错:ORA-27125。
Oracle文档上关于ORA-27125错误的描述为:
ORA-27125: unable to create shared memory segment
Cause: shmget() call failed
Action: contact Oracle support
查询了一下,发现问题和linux上的hugetbl有关。
解决方法也很简单,首先检查oracle用户的组信息:
[[email protected] ~]$ id oracle
uid=500(oracle) gid=502(oinstall) groups=502(oinstall),501(dba)
[[email protected] ~]$ more /proc/sys/vm/hugetlb_shm_group
0
下面用root执行下面的命令,将dba组添加到系统内核中:
# echo 501 > /proc/sys/vm/hugetlb_shm_group
然后启动数据库,问题消失。
但以上这种方式在重启操作系统后失效, /proc/sys/vm/hugetlb_shm_group又变为了0,建议采用以下方式解决:
加入vm.hugetlb_shm_group = 501 到/etc/sysctl.conf中来解决:
# vi /etc/sysctl.conf
加入如下的内容,其中501为dba组号,需要根据你实际的情况进行改变。
vm.hugetlb_shm_group = 501
# sysctl -p
