cd /etc
ls
gedit sysctl.conf à File open on editor mode add the following parameters

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

Run the following command to change the kernel parameters

/sbin/sysctl –p

STEP # 2:  SET PARAMETERS on LIMITS.CONF file

STEP # 3:    INSTALL REQUIRED RPM FROM LINUX CD’S 

To see which versions of these packages are installed on your system, run the following commands:
rpm -q binutils compat-db control-center gcc gcc-c++ glibc glibc-common

rpm –q gnome-libs libstdc++ libstdc++-devel make pdksh sysstat xscreensaver libaio

From CD # 2
Cd /media/cdrom/Server

rpm –Uvh gcc-3*
rpm –Uvh gcc-c++-3*
rpm –Uvh libstdc++-*

From CD # 3
Cd /media/cdrom/Server

rpm –Uvh libaio-0*  à Cd 3

 STEP # 4:    Now Perform Following Steps on ROOT User

Create 2 groups:   
groupadd oinstall
groupadd dba

Create a user and assign the above groups to user
useradd –g oinstall –G dba oracle
passwd oracle

Create directories using mkdir command
mkdir –p /u01/app/oracle

Change the ownership of above directories and allow permissions
chown  –R oracle:oinstall  /u01/app
chmod  –R 775  /u01/app

  STEP # 5:              Login As Oracle User
Gedit .bash_profile

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=ORCL; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/ jlib; export CLASSPATH

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi    fi

logout from Oracle user ….

  STEP # 8:              Login As Root User  

create folder @ /u01/app named “10g”
copy all files from cdrom to /u01/app/10g

chmod –R 775 /u01/app/10g
