Did you modify /etc/sysctl.conf according to Oracle's docs?

If not you might seriously consider logging in as root, pasting this into a terminal window, and then reading the docs for the other essential changes you didn't make.

cat >> /etc/sysctl.conf <<EOF
fs.file-max = 65536

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 1
net.ipv4.ip_local_port_range = 1024 65000 EOF
