OEL 6.3 Minimal Install VirtualBox for Database

Filed under: 11g,linux,oracle,VirtualBox — mdinh @ 4:15 am

I am a lazy DBA. The less configuration I do the less chance I have to make a mistake.

Surprisingly, oracle-rdbms-server-11gR2-preinstall does not configure pam.d/login and selinux.

Here’s how to create kernel panic with incorrect configuration.


NOTE: Configuration should be SELINUX=disabled NOT SELINUXTYPE=disabled

At the same time, I need to slow down and read more carefully.

Here is the super condensed version since there are already many blogs on how to install Linux on VirtuaBox.

Customize Minimal Install

Base System
> Base
> Client Management Tools
> Desktop
> Desktop Platform
> Graphical Administration Tools
> X Window System

NTP not configured


Disable Firewall/Disable Software Updates

yum install oracle-rdbms-server-11gR2-preinstall

Note: I did not have to modify public-yum-ol6.repo for OEL 6.3

Read more about it here

Modify /etc/grub.conf to include: divider=10

Read more about it here via @rmoff

Modify /etc/pam.d/login to include: session required

Modify /etc/selinux/config: SELINUX=disabled

Install Guest Additions.

yum clean all

Configure /etc/hosts accordingly.


As root, Configure oracle:

passwd oracle
usermod -G dba,vboxsf oracle
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oraInventory
mkdir -p /u01/app/oracle/cfgtoollogs
mkdir -p /u01/app/oracle/product/
chown -R oracle:oinstall /u01
chmod -R 775 /u01

As oracle, Modify /home/oracle/.bash_profile to include:

# User specific environment and startup programs
if [ $USER = “oracle” ]; then
if [ $SHELL = “/bin/ksh” ]; then
ulimit -p 16384
ulimit -n 65536
ulimit -u 16384 -n 65536
umask 022

export TEMP=/tmp
export ORACLE_TERM=xterm;
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/
export LD_LIBRARY_PATH=/lib:/usr/lib
export ORACLE_HOSTNAME=gg1.localdomain
export PS1=”
${LOGNAME}@`hostname -a`:\${ORACLE_SID}:\${PWD}
> ”

Install oracle software only
