<html> <body> I am trying to change the default values for kernel parameters rmem_default, rmem_max, wmem_default and wmem_max. I modify the /etc/sysctl.conf file and add rows: rmem_default = 262144 rmem_max = 262144 wmem_default = 262144 wmem_max = 262144 In case this looks familiar, I am doing this to install an Oracle database. I have set the values of other kernel parameters in this way, however, when I try to set these and execute sysctl -p, these four return a message of error: 'rmem_default' is an unknown key error: 'rmem_max' is an unknown key error: 'wmem_default' is an unknown key error: 'wmem_max' is an unknown key Do any of you have any ideas as to why these parameters will not be set? I run the command "/sbin/sysctl -a | grep rmem_default" and have a message return the current value of each of these as expected. My guess is that while I am using the specific string that the Oracle Documentation guide suggests to use to change the values of these parameters, I probably need a different syntax. Thank you, Craig</body> </html>
