Oracle Installation Prerequisites:
We can manually perform the prerequisites task:
Oracle recommend the following minimum parameter settings
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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
The current values can be tested using the following command.
/sbin/sysctl -a | grep <param-name>
Run the following command to change the current kernel parameters.
