Oracle Database Discussions

Dear Experts,
I am in the process of installing the Oracle Database 10g Release 2 on Enterprise Linux Enterprise Linux AS release 4. I Configured the Kernel Parameters as given in the instruction manual:

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

However, I got the following error when I ran this command:
[root@testdb ~]# /sbin/sysctl –p

net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.core_uses_pid = 1
error: unknown error 22 setting key 'fs.file-max'
kernel.msgmni = 2878
kernel.msgmax = 8192
kernel.msgmnb = 65536
error: unknown error 22 setting key 'kernel.sem'
kernel.shmmni = 4096
error: unknown error 22 setting key 'kernel.shmall'
kernel.sysrq = 1
error: unknown error 22 setting key 'net.core.rmem_default'
error: unknown error 22 setting key 'net.core.rmem_max'
error: unknown error 22 setting key 'net.core.wmem_default'
net.core.wmem_max = 262144
fs.aio-max-nr = 3145728
net.ipv4.ip_local_port_range = 1024 65000
vm.lower_zone_protection = 100
error: unknown error 22 setting key 'kernel.shmmax'

Please help me know why is there an error. What does the error message indicate?

Thanks in advance.
