Oracle not accept the Kurnel-Parameteres

Post by tuxianer » 2006/11/22 15:52:43

Hi together

I installed CentOS 4 on a VMWare-Server-Installation under W2k to "play" a little bit with an Oracle-Database.

Now, as i run the Oracle-Installer, he gave me some warnings:
Checking kernel parameters
Checking for semmsl=250; found semmsl=250. Passed

Check complete. The overall result of this check is: Failed <<<<
Problem: The kernel parameters do not meet the minimum requirements (see above).
Recommendation: Perform operating system specific instructions to update the kernel parameters.

Well, because i'm realy a newbie in the Linux-Administration, i've got no plan how i can change this parameters. I try it in the boot-file /boot/grub.conf. In the line which start with kernel, i placed on the end this parameters, but without sucess.

Can someone help me to describe as easiest as possible how i can change these 8 parameters.

thanks a lot
