Install Oracle in Linux

First create a host name in root user:
vi /etc/sysconfig/network
(write down)
HOSTNAME=dba
save

set in terminal hostname dba

set ip and host in
vi /etc/hosts
192.168.0.104     dba

install rpm in cd /media/RHEL_5.6\ x86_64\ DVD/Server/  directory


rpm -q binutils elfutils-libelf glibc glibc-common libaio libgcc libstdc++ make compat-libstdc++-33 elfutils-libelf-devel glibc-headers glibc-devel libgomp gcc gcc-c++ libaio-devel libstdc++-devel unixODBC unixODBC-devel sysstat kernel-headers kernel ksh libaio libXp make rsh-server


Create group and user for oracle:

/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
id oracle

passwd oracle

Create directory for oracle install:

mkdir -p /u01/app/oracle/product/11.2.0/dbhome_2
mkdir -p /u01/app/oracle/product/11.2.0/grid_1

user ownership and permission:

chown -R oracle:oinstall /u01
chmod -R 775 /u01

setting kernel parameter for the system:

vi /etc/sysctl.conf (write down below value)

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

activate kernel value by

/sbin/sysctl -p


run this value

create a directory Installer:

cd /
mkdir Installer
chmod -R 777 Installer


copy the database and grid software into Installer:
unzip file

grant ownership and permission to oracle or grid and database

chown -R oracle.oinstall /Installer
chmod -R 777 /Installer

shutdown the virtual machine for disk add:
partition the the disk:

DATA1 /dev/sdb1  
DATA2 /dev/sdb2  
DATA3 /dev/sdb3 
DATA4 /dev/sdb5  


FRA1 /dev/sdc1  
FRA2 /dev/sdc2 
FRA3 /dev/sdc3   
FRA4 /dev/sdc5


Install 3 rpm for asm library:

/etc/init.d/oracleasm configure

Configuring the Oracle ASM library driver.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Fix permissions of Oracle ASM disks on boot (y/n) [y]: y

Create disk for asm:

/etc/init.d/oracleasm createdisk DATA1 /dev/sdb1
/etc/init.d/oracleasm createdisk DATA2 /dev/sdb2 (for all)


su - oracle
