centos 5.3 kernel parameters missing, how to change/set?

Hello Experts,

I just tried to install Oracle 11g (2 attempt). The install failed because these parameters were missing or not set (I am not sure)
semopm=100; semopm=32
ip_local_port_range=1024 - 65000; ip_local_port_rage=32768 - 6100
rnem_default=4194304; rnem_default=126976
rnem_max=4194304; rnem_max=131071
wnem_default=262144; wnem_default=126976
wnem_max=262144; wnem_max=131071

how do I change/set these parameters?

thx,

regards,

The values you show are sysctl values. One would add them to /etc/sysctl.conf to have them configured centrally. The values are then read on boot or when restarting networking or manually when issuing 'sysctl -e -p /etc/sysctl.conf'. Manually changing values can be done with 'sysctl -w keynname=value' but those changes won't survive a machine reboot.

* When using Oracle products their knowledge base, called Metalink, should be your first source of information. I'm suggesting this because you're listing malformed keynames (net.core.wmem_default, not rnem) and odd values (for  net.ipv4.ip_local_port_range the range is defined as "lowvalue highvalue" so no dashes and lowest int first).
