I am having problem in installing oracle xe 11g on centos 5.7 hosted on OpenVz

The server didnt have any swap space , and the oracle installation was refusing because of the swap=0
now its has been resolved. I am having problem to set the following oracle specific kernel params

# rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
Preparing...                ########################################### [100%]
error: "Operation not permitted" setting key "fs.file-max"
error: "Operation not permitted" setting key "net.ipv4.tcp_syncookies"
error: %pre(oracle-xe-11.2.0-1.0.x86_64) scriptlet failed, exit status 255
error:   install: %pre scriptlet failed (2), skipping oracle-xe-11.2.0-1.0

How can I solve this?

    You should change this kernel parameters yourself manually and them rerun the rpm install:-

    vi /etc/sysctl.conf and add the following lines:-

    fs.file-max = 6815744
net.ipv4.tcp_syncookies = 1

    Then run

    sysctl -p

    You can see the kernel parameter settings in the Install Guide in Section 2.13, although net.ipv4.tcp_syncookies seems to be an additional setting for CENTOS
