    This is first step for step by step Installation of Oracle RAC Database on single machine using VMWare Server. for overview visit http://becomeappsdba.blogspot.com/2007/07/are-you-scared-of-oracle-rac-database.html

    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 http://rhn.redhat.com/ (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 rac1.focusthread.com 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.

      Check CM log files on why it managers are deactivating

      I am trying to install 10gR2c on my laptop using VMware.
      But I always stuk in last while installing clusterware.
      When I run root.sh . It showd me ” Failure to upgrade Oracle Cluster registry ……”

      I tried to check on internet but didn’t get any help regarding that.
      please help me

      Further please let me know is 1Gm ram is enough for installation or not.


      We replied

      Check logs at $CRS_HOME/crs/log/haystack/client/

      I did it with 2 GB but you can try on 1 GB Laptop as well. Try reducing SGA after install

      I am trying to install 10gR2c on my laptop using VMware.But I always stuk in last while installing clusterware.When I run root.sh . It showd me ” Failure to upgrade Oracle Cluster registry ……”and also unable to load shared libraries libclntsh.10.1.so

    6. Atul says:

      Dear Manjunath,
      Couple of other DBA’s were able to configure RAC successfully so check carefully each step and ensure you are doing word by word or changing your configuration as per doc if you have configured any different . We are planning to launch RAC training soon and review these steps one more time .

    7. KMG says:

      Hi Atul,
      I’ve tried several times as per your document,but its failing at root.sh on second node with “Failure at final check of Oracle CRS stack” while installaing clusterware.
      Any help will be highly appreciated.


    8. Sekaran says:

      Hi Atul,
      Can I Setup RAC in my single PC ?.
      My PC running with Enterprise Linux Operating System 5.

      Thanks for sharing your knowledge.


    9. Atul says:

      Yes, use VMware to build two virtual machine on linux.

      1. Install VMware server on Linux
      2. Build two virtual machines using vmware and install guest o.s.
      3. define shared drive & two network card on each virtual machine
      4. Install & configure RAC

    10. Ram says:

      Hello Atul,

      In the above blog you mentioned that we can download Linux from http://rhn.redhat.com site. Is it a freeware. Can we download freely from that site.


    11. Atul Kumar says:

      Only desktop version is free

      For es (enterprise server) or AS (advanced server) you need to buy license.

      Try Oracle Enterprise Linux (OEL) from Oarcle site

      Hi Atul,

      I have one question reagrding RAC; I am little bit confused about the network settings. my quesiton is can I have rac set up on my laptop at home which is not connected to any network?
      if yes then what will the network type for host and RAC1 and RAC2 virtual mahcines.

      I know you will make it clear for me and all so thanks in advance.

    16. Atul Kumar says:

      @ Muhammad Aqeel,
      If you machine is not connected to any network then define virtual network card as NAT (bridged if you are in network and router can assign IP to VM’s) .

    17. muhammad.aqeel@yahoo.com says:

      Thanks Mr. Atul,

      I will try to do it as per your advice and will update.


    18. adadmin says:

      Hi atul,

      I installed the vmware server and it has three virtual networks
      vmnet0 which is bridged
      vmnet1 which is private virtual network
      vmnet8 is NAT

      so i am going to use vmnet8 for host
      what networking type should i use for the two virtual RAC nodes.

      thanks a lot for your kind help

      We need to do a RAC 2 node upgrade from to
      Do you have steps on what needs to be taken care of before we start the upgrade?
      such as backup scripts of ocr, voting disk and Oracle homes. Kindly let me know since this is urgent
