installing oracle 11g on scientific linux 6
as root
yum -y install openssh-server
service sshd start
chkconfig sshd on
yum -y install nano
nano /etc/group
make the line look like this
wheel:x:10:root,sourav
save and exit
nano /etc/pam.d/su
uncomment the following two lines to make sourav as powerful
as root
# Uncomment the following line to implicitly trust users in
the "wheel" group.
auth sufficient pam_wheel.so trust use_uid
# Uncomment the following line to require a user to be in the
"wheel" group.
auth required pam_wheel.so use_uid
save and exit
stop and disable iptables by
/etc/rc.d/init.d/iptables stop
chkconfig iptables off
stop and disable ip6tables by
/etc/rc.d/init.d/ip6tables stop
chkconfig ip6tables off
disable selinux
by
nano /etc/sysconfig/selinux
change the line
SELINUX=enforcing to
SELINUX=disabled
save and exit
set the hostname to oracle.sourav by
nano /etc/hosts
127.0.0.1 oracle.sourav sourav localhost.localdomain
localhost
::1 localhost6.localdomain6 localhost6
save and exit
nano /etc/sysconfig/network
make the file look like this
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=oracle.sourav
save and exit
i am using dhcp so my network card file should look like this
nano /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
NM_CONTROLLED=no
PEERDNS=no
DNS1=8.8.8.8
DNS2=4.2.2.2
save and exit
to set the dns
nano /etc/resolv.conf
# Generatedby NetworkManager
search google.com
nameserver 8.8.8.8
nameserver 4.2.2.2
save and exit
to stop the NetworkManager
service NetworkMnager stop
to make sure NetworkManager won't start at the next reboot
chkconfig NetworkManager off
to restart the network
/etc/rc.d/init.d/network restart
chkconfig network on
let's reboot and let's see if everything going just fine
ok everything is fine
one more thing
let us disable ipv6 as it is not needed here
echo "install ipv6 /bin/true" > /etc/modprobe.d/disable-
ipv6.conf
ok everything is set
now let's try to install oracle's dependencies
yum -y install binutils compat-libstdc++-33 elfutils-libelf
elfutils-libelf-devel glibc glibc-common glibc-devel gcc
gcc-c++ libaio libaio-devel libgcc libstdc++ libstdc++-devel
make sysstat unixODBC unixODBC-devel
after installing now let's set some kernel parameters
nano /etc/sysctl.conf
comment out those three lines
#net.bridge.bridge-nf-call-ip6tables = 0
#net.bridge.bridge-nf-call-iptables = 0
#net.bridge.bridge-nf-call-arptables = 0
and also comment out
#kernel.shmmax = 4294967295
and
#kernel.shmall = 268435456
at the end add this section
net.ipv4.ip_local_port_range = 9000 65500
fs.file-max =65536
kernel.shmall = 10523004
kernel.shmmax = 6465333657

net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
save and exit
using the sysctl -p check out the output
it should be like
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1

ok now let's create an user for oracle
groupadd -g 200 oinstall
groupadd -g 201 dba
useradd -u 440 -g oinstall -G dba -d /usr/oracle oracle
passwd oracle
set the password
nano /etc/pam.d/login
add this line

save and exit
nano /etc/security/limits.conf
add these lines at the end
before # End of file
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024

save and exit
nano /etc/profile
at the end add these lines

chmod 775 /usr/oracle/oradata
nano ~/.bash_profile
at the end add these lines
umask 022
export ORACLE_BASE=/usr/oracle/app
save and exit
mkdir tmp
using winscp copy the oracle 11g installation files in the
target machine
ok before trying to install oracle as root you need
to execute the command xhost + in the target machine
unzip linux_11gR2_database_1of2.zip
unzip linux_11gR2_database_2of2.zip
Now to avoid pdksh error
go to

Edit cvu_config and change the following line

you will be presented with an error
environment does not meet minimum requirements error
probably a bug but i still tried installing java and some
more
steps but the same error shows up,so i ignored it and
went on
abiding by the default settings
now when asked
run this script
