QUESTION
Where can the Oracle 11.2.0.4 Client for Windows 32-bit be located or downloaded?
All that exists are Database Server patch sets.
This is due to the fact that the Database was recently upgraded to 12.2 and so any Clients less than 11.2.0.3 are not certified to connect.

This article describes the installation of Oracle Database 11g release 2 (11.2.0.3 64-bit) RAC on Linux (Oracle Linux 6.3 64-bit) using VirtualBox (4.2.6) with no additional shared disk devices.

Oracle Installation Prerequisites

Introduction

One of the biggest obstacles preventing people from setting up test RAC environments is the requirement for shared storage. In a production environment, shared storage is often provided by a SAN or high-end NAS device, but both of these options are very expensive when all you want to do is get some experience installing and using RAC. A cheaper alternative is to use a FireWire disk enclosure to allow two machines to access the same disk(s), but that still costs money and requires two servers. A third option is to use virtualization to fake the shared storage.

Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine. In addition, it allows you to set up shared virtual disks, overcoming the obstacle of expensive shared storage.

Before you launch into this installation, here are a few things to consider.

The finished system includes the host operating system, two guest operating systems, two sets of Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server. As you can imagine, this requires a significant amount of disk space, CPU and memory.
Following on from the last point, the VMs will each need at least 3G of RAM, preferably 4G if you don't want the VMs to swap like crazy. As you can see, 11gR2 RAC requires much more memory than 11gR1 RAC. Don't assume you will be able to run this on a small PC or laptop. You won't.
This procedure provides a bare bones installation to get the RAC working. There is no redundancy in the Grid Infrastructure installation or the ASM installation. To add this, simply create double the amount of shared disks and select the 'Normal' redundancy option when it is offered. Of course, this will take more disk space.
During the virtual disk creation, I always choose not to preallocate the disk space. This makes virtual disk access slower during the installation, but saves on wasted disk space. The shared disks must have their space preallocated.
This is not, and should not be considered, a production-ready system. It's simply to allow you to get used to installing and using RAC.
The Single Client Access Name (SCAN) should be defined in the DNS or GNS and round-robin between one of 3 addresses, which are on the same subnet as the public and virtual IPs. Prior to 11.2.0.2 it could be defined as a single IP address in the '/etc/hosts' file, which is wrong and will cause the cluster verification to fail, but it allowed you to complete the install without the presence of a DNS. This does not seem to work for 11.2.0.2 onward.
The virtual machines can be limited to 2Gig of swap, which causes a prerequisite check failure, but doesn't prevent the installation working. If you want to avoid this, define 3+Gig of swap.
This article uses the 64-bit versions of Oracle Linux and Oracle 11g Release 2.
When doing this installation on my server, I split the virtual disks on to different physical disks ('/u02', '/u03', '/u04'). This is not necessary, but makes things run a bit faster.

Download Software

How ot download old updates mac. Download the following software.

VirtualBox Installation

First, install the VirtualBox software. On RHEL and its clones you do this with the following type of command as the root user.

The package name will vary depending on the host distribution you are using. Once complete, VirtualBox is started from the 'Applications > System Tools > Oracle VM VirtualBox' menu option.

Virtual Machine Setup

Now we must define the two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed.

Download Oracle Client 11.2.0.3 Windows 32 Bit Download

Start VirtualBox and click the 'New' button on the toolbar. Enter the name 'ol6-112-rac1', OS 'Linux' and Version 'Oracle (64 bit)', then click the 'Next' button.

Enter '4096' as the base memory size, then click the 'Next' button.

Accept the default option to create a new virtual hard disk by clicking the 'Create' button.

Acccept the default hard drive file type by clicking the 'Next' button.

Acccept the 'Dynamically allocated' option by clicking the 'Next' button.

Accept the default location and set the size to '30G', then click the 'Create' button. If you can spread the virtual disks onto different physical disks, that will improve performance.

The 'ol6-112-rac1' VM will appear on the left hand pane. Scroll down the 'Details' tab on the right and click on the 'Network' link.

Make sure 'Adapter 1' is enabled, set to 'Bridged Adapter', then click on the 'Adapter 2' tab.

Make sure 'Adapter 2' is enabled, set to 'Bridged Adapter' or 'Internal Network', then click on the 'System' section.

Move 'Hard Disk' to the top of the boot order and uncheck the 'Floppy' option, then click the 'OK' button.

The virtual machine is now configured so we can start the guest operating system installation.

Guest Operating System Installation

With the new VM highlighted, click the 'Start' button on the toolbar. On the 'Select start-updisk' screen, choose the relevant Oracle Linux ISO image and click the 'Start' button.

The resulting console window will contain the Oracle Linux boot screen.

Continue through the Oracle Linux 6 installation as you would for a basic server. A general pictorial guide to the installation can be found here. More specifically, it should be a server installation with a minimum of 4G+ swap, firewall disabled, SELinux set to permissive and the following package groups installed:

Base System > Base
Base System > Client management tools
Base System > Compatibili
