Set Up

This section shows you how to install Oracle Database 10g R2. It will guide you through the

following steps:

Install Prerequisite package

Create required groups and users

Create directories storing oracle file

Set environment for user oracle

Configure Linux Kernel Parameter

Set shell limits for user oracle

Disable SElinux

Install Oracle

1. Install Prerequisite package

Depending on the products that you intend to install, verify that the following software is

installed on the system

Java Runtime Environment j2re-1.4.2.19

make-3.81

binutils-2.17.50.0.6

gcc-4.1.1

libaio-0.3.106

libaio-devel-0.3.106

libstdc++-4.1.1

elfutils-libelf-devel-0.125

sysstat-7.0.0

compat-libstdc++-33-3.2.3

libgcc-4.1.1

libstdc++-devel-4.1.1

unixODBC-2.2.11

unixODBC-devel-2.2.11

pdksh-5.2.14-30

openmotif21-2.1.30-11

compat-db-4.1.25-9

compat-glibc-7.x-2.2.4.32.6

compat-libstdc++-devel-7.3-2.96.128

control-center-2.8.0-12

setarch-1.6-1

libXp-1.0.0-8.1.el5

You want to check whether the packages are installed or not, run the following

command:

# rpm -q make binutils gcc libaio libaio-devel libstdc++

elfutils-libelf-devel sysstat compat-libstdc++ libgcc libstdc++-

devel unixODBC-2.2.11 unixODBC-devel

To install the package, run command:

# yum –y install libXp

2. Create required groups and users

Depending on the Oracle software being installed on this system, you need to create

operating groups and users. The groups and user required to create are dba, oinstall

group and oracle user.

To create these groups and user, enter the following command with user root:

# groupadd oinstall

# groupadd dba

# useradd -m -g oinstall -G dba oracle

# passwd oracle

Check user oracle is belong to oinstall and dba group:

# id oracle

uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

3. Create directories storing oracle files

The system need directory to store data file, configuration. You create the folder /u01 and

assign right to it

# mkdir -p /u01/app/oracle/product/10.2.0

# chown -R oracle:oinstall /u01/app

# chmod -R 775 /u01/app

4. Set environment for user oracle

Log into the oracle user.

If you are using X emulation then set the DISPLAY environmental variable:

DISPLAY=<machine-name>:0.0; export DISPLAY

Edit file /home/oracle/.bash_profile and insert the following line:

#environment for oracle

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

ORACLE_SID=fsrvorcl

PATH=$PATH:$ORACLE_HOME/bin

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/j

lib

export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH

CLASSPATH

5. Configure Linux Kernel Parameter

Using gedit to add below information to file /etc/sysctl.conf

#This lines is for Oracle Installation

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 6553600

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 4194304

net.core.wmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_max = 262144

Checking result, enter command:

#sysctl –p

6. Set shell limits for user oracle To improve the performance of the software on Linux system, you must increase the

following shell limits for the oracle user.

As root, edit file /etc/security/ limits.conf and insert some text before # End of file

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft nproc 2047

oracle hard nproc 16384

Verify file /etc/pam.d/system-auth to check the existing of two following lines:

session required /lib/security/pam_limits.so

session required pam_limits.so

If you don’t see the first line, insert it.

7. Disable the SElinux

Edit file /etc/selinux/config, find SELINUX and change it to

SELINUX=disabled

8. Install Oracle

The oracle 10gR2 is compatible with some linux :Red Hat Enterprise 3, 4 but not

CentOS 5. While installing oracle, the error will prompt in installation check. You

need to edit file /etc/redhat-release and change its content:

redhat-4

Start the Oracle Universal Installer (OUI) by issuing the following command in the

Oracle source directory:

./runInstaller

On installation method screen, choose Basic Installation. Check the Oracle home

# /u01/app/oracle/product/11.1.0/db_1/root.sh

# exit

# exit <- close terminal

Click Ok

Click Exit on End of Installation screen to complete.
