[Oracle] - Install Oracle12cR1 on Oracle Linux 6.5 in VirtualBox

My Oralce Linux 6.5 is running on VirtualBox. Basic settings is 4G memory, 50G hard-disk, auto partition when install OL6.5.

 

** Following series of operations need root privilege.

1. Edit /etc/hosts

Add your hostname. For example, you host name ol65.localdomain then

127.0.0.1   localhost localhost.localdomain ol65 ol65.localdomain
::1              localhost localhost.localdomain ol65 ol65.localdomain

When you install oracle linux6.5 there is one step ask domain name. You should add it into /etc/hosts before you start installing. If there is no this domain name there will be an error, installation can't continue.

PRVF-00002: Could not retrieve local nodename

Cause: Unable to determine local host name
using Java network functions.

Action: Ensure that hostname is defined correctly using the 'hostname' command.

2. Add or amend the following lines to the /etc/sysctl.conf

fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

3. Run the following command to change the current kernel parameters

/sbin/sysctl -p

4. Add the following lines to the /etc/security/limits.conf

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    2047
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768

6. Create new group and user

**I install Oracle for learning so I simplified this, only created one new user who will be in charge of all oracle related operations. This's not suitable to product environment.

groupadd -g 54321 oracle
useradd -u 54321 -g oracle oracle
passwd oracle

7. Amend the /etc/security/limits.d/90-nproc.conf

# Change this
*          soft    nproc    1024

# To this
* - nproc 16384

8. Change the setting of SELinux to permissive by editing the /etc/selinux/config

SELINUX=permissive

9. Set firewall to enable Oracle DB ports

Open 1521 and 5500, up to you.

10. Create a new file and change its owner

touch /etc/oratab
chown -R oracle:oracle /etc/oratab

11. Create install directory

mkdir -p /u01
chown -R oracle:oracle /u01

** Login as oracle

12. Unzip installer and run installer

Unzip linuxamd64_12102_database_1of2.zip and linuxamd64_12102_database_2of2.zip

Go into database folder

Run ./runInstaller

13. Install

** Stop here! Open console, login as root, run these two scripts

1) /u01/app/oraInventory/orainstRoot.sh

[root@ol65 oraInventory]# ./orainstRoot.sh

Completed!

14. Access EM Database Express URL to test

15. Login as oracle and edit ~/.bash_profile

Add below part inside

# Oracle12c Settings
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=oracle12c.localdomain
export ORACLE_UNQNAME=oracle12c
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1
export ORACLE_SID=orcl
export PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

16. Set auto startup

Login as root

1) Edit /etc/oratab, change N to Y as below

orcl:/u01/app/oracle/product/12.1.0/dbhome_1:Y

2) Create file /etc/init.d/dbora and add following content

#!/bin/sh
# chkconfig: 345 99 10
# description: Service to start and stop Oracle Database and Listener
#
# processname: oracle
# config: /etc/oratab
# pidfile: /var/run/oracle.pid

# Source function library.
. /etc/init.d/functions

RETVAL=0
ORA_OWNER="oracle"
ORA_HOME="/u01/app/oracle/product/12.1.0/dbhome_1"

# See how we were called.

prog="oracle"

start() {
echo -n $"Starting $prog: "
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart $ORA_HOME"
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/dbora

return $RETVAL
}

stop() {
echo -n $"Stopping $prog: "
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut $ORA_HOME"
RETVAL=$?

echo
[ $RETVAL -eq 0 ] && rm -r /var/lock/subsys/dbora

return $RETVAL
}

restart() {
stop
start
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac

exit $?

ORA-OWNER and ORA_HOME should math your own condition.

Next you need to run the following commands to change permissions and make the service active.

chgrp oracle /etc/init.d/dbora
chmod 755 /etc/init.d/dbora
chkconfig --level 345 dbora on

3) Reboot server

reboot

Congratulation!
