Class Materials:
- CentOS 6.4 64-bit install media
Before we can install Oracle 12cR1 on our new VM, we need to load additional RPM packages that are required by the Oracle database and grid.

Oracle 12cR1 12.1.0.1 2-node RAC on CentOS 6.4 on VMware Workstation 9 – Part I
Time Required: 60 minutes
Class Materials:
- 60GB of free disk
- An operational VMware Workstation 9 or later install
- CentOS 6.4 64-bit ISO install media
To create our Oracle 12c RAC database on VMware Workstation 9, we first need to create a Linux VM.
Oracle 12c will eventually be released for a multitude of platforms, but the initial release only support Solaris SPARC, Solaris x86 and Oracle Linux 6.4.
I don’t own a SPARC machine, so instead I am going to install Oracle 12c RAC on CentOS 6.4.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Intro
A while back I put together a very detailed ten step process to create a simple two-node RAC on VMware Workstation using Red Hat Linux 5.5.
There were already many blog posts on creating RAC systems, including some using VMware, but partly because I felt that none of them were detailed for someone not already an expert in Linux, and partly because I wanted to learn for myself, I created my own.
Oracle 12c RAC runcluvfy.sh error: prerequisites on this operating system distribution
During an install of Oracle 12cR1 RAC Grid Infrastructure on Red Hat or CentOS 6.2, 6.3 or 6.4, you run the runcluvfy.sh script to test node readiness and it fails with the following error:
ERROR: Reference data is not available for verifying prerequisites on this operating system distribution Verification cannot proceed
This is due to bug 15973656 which states that runcluvfy.sh cannot properly detect the Red Hat 6.2 and above operating system. The problem also affects CentOS 6.2 and above.
[INS-41112] Oracle 12c RAC Grid Install error
When installing Oracle 12c RAC, the Grid Installer fails with:
Specified network interface doesn't maintain connectivity across cluster nodes.
This error is caused when the Linux firewall is still operational.
Log in as root, shutdown and disable the firewall on all nodes of the cluster:
[root@ora12a ~]# service iptables stop iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Unloading modules: [ OK ] [root@ora12a ~]# chkconfig iptables off
Now retry the Grid installer step and it should succeed.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Part VIII
Time Required: 60 minutes
Class Materials:
- Oracle 11gR2 Grid Infrastructure software for Windows
Next we are going to install the Oracle Grid Infrastructure software.
The Grid Infrastructure will provide the Cluster software that allows the RAC nodes to communicate, as well as the ASM software to manage the shared disks.
To begin, download the zip file from the Oracle software download website and unzip on Rodolfo.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Part X
Time Required: 10 minutes
Class Materials:
- none
Next we are going to create a new RAC database using DBCA.
Open a new command window to make sure all environment settings are established. Do not re-use the same window you used to install the Grid and Database.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Part IX
Time Required: 60 minutes
Class Materials:
- Oracle 11gR2 Database software for Windows
Next we are going to install the Oracle Database 11gR2 11.2.0.3 software.
To begin, download the two zip files from the MOS and unzip on Rodolfo. Make sure you are logged into Rodolfo as the oracle user.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Part VII
Time Required: 30 minutes
Class Materials:
- 5GB of disk space
- an ASCII text editor
Next we are going to add a shared disk to our two Windows VMs.
VMware Workstation makes the allocation of shared disk to VMs very simple. Shared disk has been the biggest obstacle to create Oracle RAC clusters at home, but VMware gives us a reliable and portable solution that does not require fire-wire hacks, your own NFS server or a SCSI disk array.
Oracle 11gR2 11.2.0.3 2-node RAC on Windows 2008 on VMware Workstation 9 – Part VI
Time Required: 20 minutes
Class Materials:
- none
We are now ready to clone our VM. From this point forward we will have two machines, and we will start to think of them individually.
Make sure your Windows VM is shutdown.
