Oracle Installation Prerequisites on Linux

Automatic setup As root user perform the prerequisite setup. Issue the command

yum install oracle-rdbms-server-12cR1-preinstall -y


Configure /etc/resolv.conf file

Search workgroup Nameserver 192.168.56.1

Write protecting /etc/resolv.conf file

The changes to /etc/resolv.conf can be overwritten by the network manager due to NAT interface. To avoid this you can write protect this file. you can make the file readonly as below

# chattr +i /etc/resolv.conf

+i attribute write protect etc/resolv.conf file under Linux so that no one can modify it. But root can

Configure /etc/security/limits.d/90-nproc.conf

# Change this

* soft nproc 1024 # To this

* - nproc 16384

Change the setting of SELinux to disabled by editing /etc/selinux/config file

SELINUX=disabled

Add the local addressed on /etc/hosts and also other addresses for reference.

The Virtual machine setup is now complete. Before installing Oracle, shutdown the VMs and take snapshots of them as you can always rollback to this Restore point if any issue with Grid installation. Just rollback to this point, cleanup the disks and start the install again. Alternatively you can backup the whole RAC VM Group and replace them in the event of failure. Create a Backup for both nodes and clone a 3rd Node if required Create a Snaphot ( Restore Point 1) for both Nodes Shutdown both nodes

Shutdown –h now

Ol6-121-rac1 – OS Restore Point 1 Ol6-121-rac2 – OS Restore Point 1 Select Node1, click snapshots

Take Snapshot for Node1


Provide a snapshot name for ol6-121-rac1 and click OK

Take snapshot for Node2
