[Users] sysctl. error: permission denied on key 'fs.file-max'

[José Miguel Gago Huguet]

I started to install Oracle 10g on a virtualized CentOs 5.4. The CentOS is
running over a openvz container. I have followed the steps of this link:
http://wiki.openvz.org/Oracle_10g_VE. And I get the following errors

 /sbin/sysctl -p
net.ipv4.ip_forward = 0
error: permission denied on key 'net.ipv4.tcp_syncookies'
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
error: permission denied on key 'fs.file-max'
error: permission denied on key 'net.ipv4.ip_local_port_range'
error: permission denied on key 'net.core.rmem_default'
error: permission denied on key 'net.core.wmem_default'
error: permission denied on key 'net.core.rmem_max'
error: permission denied on key 'net.core.wmem_max'

Does anybody knows about the problem?
