030 - To show kernel parameters

Submitted by Anonymous on Thu, 12/11/2008 - 18:26

For Oracle instration, You should check the kernel parameters by the following command, though Oracle
installer checks the values, before installation will proceed.

[root@myserver ]# /sbin/sysctl -a | grep 'sem|shm|file-max|ip_local'

net.ipv4.ip_local_port_range = 1024   65000
vm.hugetlb.shm_group =0
kernel.sem = 250     32000   100   128
kernel.shmmni = 4096
kernel.shmmall = 2097152
kernel.shmmax = 2147483648
fs.file-max = 65536

[root@myserver]#

If You want to change these values, you can edit the file /etc/sysctl.conf and immediately bu running
the command /sbin/sysctl -p. These values will be set automatically in the future when your server starts.
