    Step by Step build RAC : Part 1 : Install VMWare and Linux
    Monday, July 09, 2007
    Register for R12 upgrade
    This is first step for step by step Installation of Oracle RAC Database on single machine using VMWare Server. for overview visit

    Broad level for Part I Install VMWare and Linux
    - Download, Register and Install VMWare Server
    - Download and Install Red Hat Linux ES 3
    - Add virtual network card for interconnect
    - Add virtual shared shared disk (voting disk, ocr and ASM)

    1.1 Install VMWare Server on Windows Machine

    Download and install VMWare Server from VMWare Site (click here) (Download windows version as we are installing on windows desktop/laptop). You have to register for VMware Server on site mentioned above to recieve licence key used in installation of VMWare Server

    1.2 Create Virtual Machine

    --Start VM Ware server console from Start Menu on your windows operating system

    --Create a New Virtual Machine by “Ctrl + N” or File -> New -> Virtual Machine (From Console Tool Bar)

    Since we are installing Red Hat Enterprise Linux 3 so I have selected Version Red Hat Enterprise Linux 3

    Select location where you wish to keep this RAC Machine Configuration and Linux Disks

    Create this Linux Machine of size 15 GB, we will add another 5GB each for voting disk, ocr and ASM for data files.

    1.3 Download/Order and install Red Hat Linux E.S. 3

    Download red hat enterprise server linux version 3 from (You can install any other linux version or operating system depending on availability. For this step by step Oracle RAC installation, I used Red Hat ES 3)

    If you have downloaded Red Hat ES burn them as iso images.

    Insert Disk1 of Red Hat Linux ES3 in your desktop/laptop and start RAC1 virtual Machine created above

    During Disk Setup select Automatic Disk Partition and when you get this screen edit by clicking edit button and change swap space to 1500 MB

    During Package Selection, Select Customize Package list and Add KDE Desktop Environment and Development Tools from list

    Select No Firewall

    During hostname enter machine name as this you can change later as well

    1.4 Create User oracle:oracle

    Create operating system user oracle (By default it will create group oracle and assign this to user oracle). You can use GUI as shown below or command useradd

    Coming Next

    Adding Virtual Network Card , Virtual Disks, install RPMs, Cloning RAC1 to RAC2 Machine, Configure User Equivalency ........

      We have just upgraded to 2 nodes RAC but the concurrent manager status keeps changing to inactive manager intermittently.

      The System profile
      Concurrent:OPS Request Partitioning is OFF and Concurrent:PCP Instance Check is ON

      Any advise on what else to check or do.

      I had downloaded Latest VMServer and VmServer Console.

      I installed both on WindowsXp.

      After installing, i restarted the System, then started the Vmware Server Console.

      Got two Options in the screen,
      Local Host
      Remote Host.

      I selected Local Host and click on the connect.
      But Getting Error .. ??

      I tried the Same scenario on Windows 2003 Server, But the same problem exists.

      Then downloaded the VMware Workstation.

      Installed Both the VMWorkstatio and VMware Server Console.

      This time the Error was different.
      finally unable to connect to local host.

      If VMWare products are successsfully installed then we can test the installation of RAC as sepecified the above.

      Please help in this regard.
      Any one...??

      hi atul.
      first of all thanks for compiling the docs in such a great fashion.
      I have one proble:
      I did all the preparatory steps fpr RAC installation. I did all the tests for user equivalency and cluster verify, ssh login without fail:
      now my /etc/hosts file had host localhost entry
      i added all the network details in this file
      during ./runInstaller of clusterware
      it shows that nodes are not cluster configured.
      i did a lot of R&D and modifie the /etc/hosts file like anything
      even then i am not able to install the clusterware

      any idea on this
