kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65535

Hi,
   For editing /etc/sysctl.conf, you need root privileges. Please login as root or ask your system administrator to do so.
If you are in ubuntu, may be, you can edit using
sudo vi /etc/sysctl.conf , it will ask you password and then you can proceed.

There is a '#' sign after sysctl.conf file

if I want to edit that file I have to update next line or same line...
what is the meaning of '#' sign in that file..

here is the file
===================================================
#
# /etc/sysctl.conf - Configuration file for setting system variables
# See /etc/sysctl.d/ for additional system variables.
# See sysctl.conf (5) for information.
#

#kernel.domainname = example.com

# Uncomment the following to stop low-level messages on console
#kernel.printk = 3 4 1 3

#net.ipv4.conf.all.log_martians = 1

# is a comment in most of the Unix configuration files. When you see a # in the start of the line, it means it is commented and the system ignores the line.

Let me please explain  the problem in details.....

mathew@mathew-Inspiron-1501:/etc$ ls -l sysctl.conf
-rw-r--r-- 1 root root 2084 2010-06-08 11:38 sysctl.conf

according to this the file is read write that means we can edit and save.
And I tried to do so..

Following is the result:

according to the installation step I have to add and save the following part to the sysctl.conf file
here is the part
---------------------------------
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 1048576
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65535
--------------------------------------------------------

When I edited and save here is the message I get..

used the short cut ZZ(shift + zz)

Here is the message at the bottom
# Do not accept IP source route packets (we are not a router)
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv6.conf.all.accept_source_route = 0
#
io-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 1048576
net.core.wmem_max = 1048576

E45: 'readonly' option is set (add ! to override)

Could you please help me to solve this issue

Thanks in advance..

that issue was taken care of /etc did not have permissions it was taken care of..
Now the issue is run installer error

it shows the error like this..
mathew@mathew-Inspiron-1501:~/Desktop/database$ ./runInstaller
/home/mathew/Desktop/database/install/.oui: 2: Syntax error: ")" unexpected
mathew@mathew-Inspiron-1501:~/Desktop/database$ ./runInstaller
/home/mathew/Desktop/database/install/.oui: 2: Syntax error: ")" unexpected
mathew@mathew-Inspiron-1501:~/Desktop/database$ "./runInstaller"

/home/mathew/Desktop/database/install/.oui: 2: Syntax error: ")" unexpected
mathew@mathew-Inspiron-1501:~/Desktop/database$

what is the expected syntax what could be the error here.

Thank you in advance.
