To install Oracle 11g, some of the kernel parameter needs to be fine tuned :
1) Open /etc/sysctl.conf and insert the following data :
kernel.sem = 250 32000 100 128
kernel.shmmax = 536870912
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65500
run sudo /etc/sysctl -p
2) Open /etc/limits.conf and insert the following :
ges hard nofile 65536
ges soft nofile 65536
ges hard nproc 16384
