sysctl: permission denied on key

AWS ec2 ubuntu 서버에

오라클DB 설치과정중 커널파라미터 값 설정을 한후 적용하려고 하니 에러가나왔다.

ubuntu@green:~$ sudo vi /etc/sysctl.conf


fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4056393728
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

#작성후 :wq!

sudo /sbin/sysctl -p 명령어로 적용시킬수있다.
