Create VirtualBox Image OEL73 as our RAC Provisioning Server
After basic OS Installation install some helpful YUM packages
[root@ractw21 ~]# yum install system-config-users
[root@ractw21 ~]# yum install wireshark
[root@ractw21 ~]# yum install wireshark-gnome
Install X11 applications like xclock
[root@ractw21 ~]# yum install xorg-x11-apps
[root@ractw21 ~]# yum install telnet
Use the “oracle-database-server-12cR2-preinstall” package to perform all your prerequisite setup
[root@ractw21 ~]# yum install oracle-database-server-12cR2-preinstall -y
Perpare Network
Change the setting of SELinux to permissive by editing the "/etc/selinux/config" file, i
making sure the SELINUX flag is set as follows.
SELINUX=permissive
If you have the Linux firewall enabled, you will need to disable or configure it, as shown
here or here. The following is an example of disabling the firewall.
Disable AVAHI daemon [ only if running ]
# /etc/init.d/avahi-daemon stop
To disable it:
# /sbin/chkconfig avahi-daemon off
Stop Firewall
[root@ractw21 ~]# systemctl stop firewalld
[root@ractw21 ~]# systemctl disable firewalld
[root@ractw21 ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Potential Nameserver issues
Make sure the "/etc/resolv.conf" file includes a nameserver entry that points to the correct nameserver.
Also, if the "domain" and "search" entries are both present, comment out one of them. For the OS installation
my "/etc/resolv.conf" looked like this.
#domain localdomain
search localdomain
nameserver 192.168.1.1
The changes to the "resolv.conf" will be overwritten by the network manager, due to the presence of the
NAT interface. For this reason, this interface should now be disabled on startup. You can enable it manually
if you need to access the internet from the VMs. Edit the "/etc/sysconfig/network-scripts/ifcfg-enp0s3" (eth0)
file, making the following change. This will take effect after the next restart.
ONBOOT=no
Modify resolv.conf and reboot the system:
# Generated by Helmut
search example.com
nameserver 192.168.5.50
Afer a reboot we have following IP setting and Nameserver loopup should working fine
[root@ractw21 ~]# ifconfig

Switching between RAC and Internet ACCESS Networking
RAC Networking
- enp0s3 down - No IP V4 address assigned
- /etc/resolv.conf points to our RAC Nameserver 192.168.5.50
- RAC Nameserver is working
- BUT Internet access is disabled
[root@ractw21 ~]# ifdown enp0s3
Device 'enp0s3' successfully disconnected.
[root@ractw21 ~]# ifconfig
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Address: 192.168.5.141
Internet Access Networking
Note we may need to have Internet access for running yum, ...
- activate enp0s3
- /etc/resolv.conf points to our Router Gateway 192.168.1.1
- RAC Nameserver is NOT working
- Internet access is enabled
[root@ractw21 ~]# ifup enp0s3
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)
[root@ractw21 ~]# ifconfig enp0s3

Note if ping google.de does not work you may need to add following entrry to

Creating Installation directories
Oracle GridHome restrictions
It must not be placed under one of the Oracle base directories, including the Oracle base
directory of the Oracle Grid Infrastructure installation owner.
It must not be placed in the home directory of an installation owner. These requirements
are specific to Oracle Grid Infrastructure for a cluster installations.
Create Directories:
- Have a separate ORACLE_BASE for both GRID and RDBMS install !
Create the Oracle Inventory Directory
To create the Oracle Inventory directory, enter the following commands as the root user:
[root@ractw21 ~]# mkdir -p /u01/app/oraInventory
[root@ractw21 ~]# chown -R grid:oinstall /u01/app/oraInventory
Creating the Oracle Grid Infrastructure Home Directory
To create the Grid Infrastructure home directory, enter the following commands as the root user:
Creating the Oracle Base Directory for Grid User
[root@ractw21 ~]# mkdir -p /u01/app/grid
[root@ractw21 ~]# chown -R grid:oinstall /u01/app/grid
[root@ractw21 ~]# chmod -R 775 /u01/app/grid
Creating GridHome
[root@ractw21 ~]# mkdir -p /u01/app/122/grid
[root@ractw21 ~]# chown -R grid:oinstall /u01/app/122/grid
[root@ractw21 ~]# chmod -R 775 /u01/app/122/grid
Creating the Oracle Base Directory for Database Software
To create the Oracle Base directory, enter the following commands as the root user:
[root@ractw21 ~]# mkdir -p /u01/app/oracle
[root@ractw21 ~]# chown -R oracle:oinstall /u01/app/oracle
[root@ractw21 ~]# chmod -R 775 /u01/app/oracle
Create file /etc/oraInst.loc wiht following content
<inventory_loc=/u01/app/oraInventory
inst_group=oinstall
Modify .bashrc scripts for users oracle and grid
Add following lines to grid user .bashrc script
export ORACLE_BASE=/u01/app/grid
export ORACLE_SID=+ASM1
export GRID_HOME=/u01/app/122/grid
export ORACLE_HOME=$GRID_HOME

Verify our newly created VM with cluvfy
Prepare 12.2 Clufy Usage and Cluvfy log File Location
Create a shared Folder and mount the Installation media
[root@ractw21 ~]# mkdir /kits
[root@ractw21 ~]# mount -t vboxsf kits /kits
[root@ractw21 ~]# su - grid
Extract the GRID Zip file on your VBox Host Computer ot get access to Cluvfy Tool ./runcluvfy.sh
The runcluvfy.sh script contains temporary variable definitions which enable it to
run before you install Oracle Grid Infrastructure or Oracle Database.
After you install Oracle Grid Infrastructure, use the cluvfy command to check
prerequisites and perform other system readiness checks.
Add the proper protections for grid and oracle user to get access to the GRID media
[root@ractw21 ~]# usermod -G vboxsf -a grid
[root@ractw21 ~]# usermod -G vboxsf -a oracle
Run Cluvfy from 12.2 Installation Media and print the cluvfy version number
Clufy logs [ very usefull ] are found under $ORACLE_BASE of our grid user
[grid@ractw21 ~]$ ls -ld $ORACLE_BASE
