    Are you scared of Oracle RAC Database ?
    Tuesday, July 03, 2007
    Register for R12 upgrade
    I saw an interesting post on Oracle Real Application Cluster Database at Kirk'S Blog Who's afraid of the big bad RAC

    Biggest challenge in learning / understanding RAC is lack of hands on experience because of expensive hardware, network cards, interconnect and cluster file system. In this and coming posts I'll cover step by step Oracle RAC installation and configuration on single laptop/desktop using VMWare Server without investing anything extra on hardware (using two virtual machines, virtual network cards and virtual shared disk for Oracle RAC database shared files system ).

    Here are broad level steps for configuring/building Oracle RAC Database on laptop/desktop machine (without investing any thing on hardware).

    -- Install VMWare Server on your desktop or laptop
    -- Create a Virtual Linux Machine RAC1
    -- Install Linux Operating on RAC1
    -- Add virtual shared disk for voting disk, ocr and ASM
    -- Add virtual network card for private interconnect
    -- Configure network card and virtual shared disk
    -- Clone Virtual Machine from RAC1 and RAC2
    -- Configure User Equivalency and other Oracle RAC prereqs.
    -- Download and install Oracle RAC Software (Clusterware)
    -- Download and install RAC Database software using ASM

    Download :
    Download following software required in building your own Oracle RAC Database
    -- Download VMWare Server Console
    -- Download Red Hat Linux ES 3
    -- Download Oracle Database ( & Oracle Clusterware (

      CentOS works just fine. I have now 10G database and application on two different notebooks. Next time I will use WMware on CentOS to install RAC on one + Application on another PC.
      Great site Atul!

      Hi Atul,

      Great site.... i am in the process of installing RAC on Linux ES5 on my laptop. I had on question in mind. Does the RAC setup using VMWare requires 4 GB RAM or is 2 GB sufficient.

    • At 6:49 AM, Blogger vinod said…

      Hi Atul,

      Can I use Red Hat Linux 9?

    • At 1:04 PM, Blogger Subha said…

      HI Atul,
      I saw umpteen number of fabulous comments. Hats off to your work.

      I am working on RAC setup on Windows these dayz to test our product. However, I have few queries:

      1) Do i need to create Voting Disk partition and OCR partition on every node in the cluster? As per my understanding, it is only required on the shared storage machine. Please correct me if i am wrong.

      2) How do i establish a connection between the shared storage and the clustered nodes? Host file entry?

      Thanks in advance.
