Let’s play with Oracle RAC 11g and Oracle Enterprise Linux 5- Part I

2. The Software

You can download all software you will need to this project at the following urls:

• https://www.vmware.com/tryvmware/?p=workstation-w
• http://www.oracle.com/technology/software/products/database/index.html
• http://edelivery.oracle.com/linux
• http://oss.oracle.com/projects/ocfs2

3. Virtual Machine Rac1 Setup

We are going to create 2 virtual machines (Rac1 and Rac2) that will share 5 disks (asm1, asm2, asm3, ocfs2 and local disk).

First we will create the windows folders to have the virtual machines and the shared storage.

• C:\Users\francisco\Documents\labs-virtual-machines\RAC\rac1
• C:\Users\francisco\Documents\labs-virtual-machines\RAC\rac2
• C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage

1. Then Double-click on the VMware Icon your desktop to bring up the application:

2.   Click on the New Virtual Machine Icon.

3. New Virtual Machine Wizard: Click on Next.

4. In the Select the Appropriate Configuration Window Select Custom and then press next.

5. Press Next in the Compatibility Window.

6. Select a Guest Operating System:

• a. Guest operating system: Select Linux.
• b. Version: Select Red Hat Enterprise Linux 5.

c. Press Next

7. Name the Virtual Machine:

• a. Virtual machine name: Enter rac1
• b. Location: En
  ter C:\Users\francisco\Documents\labs-virtual-machines\RAC\rac1\
• c. Press Next

8. Processor Configuration

• a. Number of processors: Select Two
• b. Press Next

9. Memory for the Virtual Machine

• a. Memory: Enter 860 MB
• b. Press Next

10. Network Type

• a. Network Connection: Select Use bridged networking
• b. Press Next

11. Select I/O Adapter Types

• a. SCSI Adapters: Select LSI Logic
• b. Press Next

12. Select a Disk:

• a. Disk: Select create a new virtual disk.
• b. Press Next

13. Select a Disk Type:

• a. Virtual Disk Type: Select SCSI (Recommended).
• b. Press Next

14. Specify Disk Capacity:

• a. Disk capacity: Enter 8GB and Select Allocate all disk space now.
• b. Press Next

15. Specify Disk File:

• a. Disk file: Enter localdisk
• b. Click on Finish.

16. Now we will create the rest of shared disks:

• a. VMware Server Console: Click on Edit virtual machine settings.

17. Add Hardware Wizard: Click on Next.

18. On Hardware Type:

• a. Hardware types: Select Hard Disk
• b. Then click on Next

19. Select a Disk:

• a. Disk: Select Create a new virtual disk.
• b. Then Click Next

20. Select a Disk Type:

• a. Virtual Disk Type: Select SCSI (Recommended).
• b. Mode: Select Independent
• c. Mode: Select Persistent
• d. Then Click Next

21. Specify Disk File:

• a. Disk file: Enter “C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage\ocfs2.vmdk”
• b. Then Click Next

22. Specify Disk Capacity:

• a. Disk capacity: Enter “1.0GB”
• b. Select Allocate all disk space now.
• c. Then Click Finish

Repeat steps 16 to 22 to create all the other virtual SCSI hard disks:

• asm1.vmdk, C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage\asm1.vmdk (3GB),
• asm2.vmdk, C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage\asm2.vmdk (3GB),
• asm3.vmdk, C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage\asm3.vmdk (3GB).

Then when finish you will have something like this:

Add an additional virtual network card for the private interconnects:

• a. VMware Server Console: Click on Edit virtual machine settings.
• b. Hardware types: Ethernet Adapter.
• c. Then Click Next

On Network Type:

• a. On Network Connection Select Bridget: Connect directly to the physical network
• b. Click on Finish.

Then Select Floppy then:

• a. click on Remove
• b. Then OK.

Like you see the hard drives are showing:

• Hard Disk (SCSI 0:0) 8 GB
• Hard Disk (SCSI 0:1) 1 GB
• Hard Disk (SCSI 0:2) 3 GB
• Hard Disk (SCSI 0:3) 3 GB
• Hard Disk (SCSI 0:4) 3 GB

Now we need to change them to look like this:

• Hard Disk (SCSI 0:0) 8 GB
• Hard Disk (SCSI 1:0) 1 GB
• Hard Disk (SCSI 1:1) 3 GB
• Hard Disk (SCSI 1:2) 3 GB
• Hard Disk (SCSI 1:3) 3 GB

To make this possible we will give double-click over the hard disk showing SCSI 0:1

• a. Then Click on Advanced

Then Change Virtual Device node

• a. From SCSI 0:1 Hard Disk (SCSI 0:1)
• b To SCSI 1:0
• c. Then Click OK
• d. Then Click OK one more time

Repeat these steps to change:

• Hard Disk (SCSI 0:2) 3 GB to SCSI 1:1
• Hard Disk (SCSI 0:3) 3 GB to SCSI 1:2
• Hard Disk (SCSI 0:4) 3 GB to SCSI 1:3

Now to finish this virtual machine, edit the file C:\Users\francisco\Documents\labs-virtual-machines\RAC\Red Hat Enterprise Linux 4.vmx.

               a. Then add the following lines to it like the example bellow:

disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
scsi1.sharedBus = "virtual"

scsi1:1.mode = "independent-persistent"

scsi1:2.present = "TRUE"

scsi1:2.fileName = "C:\Users\francisco\Documents\labs-virtual-machines\RAC\shared_storage\asm2.vmdk"

Ok, let’s finish here for today folks. Tomorrow I’ll explain how to create the second node and to install the Oracle Enterprise Linux 5
