I only use a single space between variables, looks like you have multiple spaces or maybe even tabs, try just putting a single space between. Don't know if that will solve the problem or not, but I would start there. Your config: kernel.sem 250 32000 100 128 Suggestion: kernel.sem 250 32000 100 128 Also you setup for ipv4 needs to be corrected Your config: net.ipv4.ip_local_port_range 32768 65000 Suggestion: net.ipv4.ip_local_port_range = 32768 65000 Hope that help! -=Steve -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Dave Martini Sent: Friday, November 10, 2006 1:20 PM To: Red Hat List Subject: sysctl.conf file not being read at bootup? I have an RHEL WS 4.0 host. I'm setting the kernel parameters for Oracle in /etc/sysctl.conf. When I reboot the machine the parameters never get set to what I've specified in my /etc/sysctl.conf file. Is there a reason for this? Notice the net.ipv4.ip_local_port_range is set to 65000 in sysctl.conf but after rebooting shows 61000. And the 3rd. value of kernel.sem is set to 100 in sysctl.conf but shows 32 after reboot.
