    Hi ronny,
    I was wondering if you can advise me of buying a hardware for me to install oracle Application with 10gRAC on OEL 5.3 with oracle vmware.
    is this system need to be bare bone or if there is window OS installed that can be wipedout and Linux can be installed?
    I have implemented oracle apps and middleware on several unix system which was already configured by OS sysAdmin but never have done by myself on any bare bone Pc or server !!

    Hi Nikhil,
    at least i will try.
    I understand from your question that you want to build a 10g RAC with OEL 5.3 as operating system with some kind of virtualization (either VMWARE or Oracle VM).

    So let me starting with some remarks:
    - RAC mean at least TWO nodes (or systems); if you use virtualization you might get away with one system but that should be used for educational purposes only
    - VMWARE (ESX or ESXi) is an operating system on it´s own. It is installed on the server (plus some management interface) just like an operating system. With the
    VMWARE Management Console you create your virtual machines, start them and install the operating system there.
    - Oracle VM is also installed like an operating system. If you installed OEL or Red Hat before you will notice the installer is the same and asking the same questions.
    After installation you need to create VMs and install an operating system there.
    - Note that RAC in virtualized environments is only supported on Oracle VM!

    The Hardware needed for running a RAC is low: at least 2 Cores (one for each node) and at least 4 GB memory (2 GB for each node).
    The 2 GB memory for each node are required for the operating system itself (1 GB) plus the clusterware components (1 GB). If you
    need a database instance (of course you do) just add the amount of memory you need to each node. For the oracle application
    component you also need some memory.

    So my basic recommendation for starting would be: a Quad-Core-CPU with 16 GB memory for a two-node rac cluster.
    Required space per node is approx 100 GB plus database size.

    Ronny
