Oracle 10g RAC using NFS…


I’ve mentioned it before, but I really like Kevin Closson‘s blog. For some time he’s been evangelizing about Oracle RAC over NFS, so I thought I would give it a go to see what it’s all about and here is the result.

Oracle 10g RAC On Linux Using NFS

I was only using two machines, and I didn’t have access to a NAS that supported NFS, so I was forced to use one of the RAC nodes as my NFS server. I know it’s a dumb idea, but it proves the technology.

If you are just playing about, the nice thing about this solution is you don’t need to worry about “real” shared storage. I prefer it to the VMware approach because you don’t need a single server with loads of memory to fake two virtual machines and the shared storage. Finding two poor machines is always easier than 1 good one. 🙂

  1. Tim,

    Outrageous, excellent job on this step by step setup procedure for RAC on NFS! It is up to date, and very crisp and concise! It also shows how simple it is to get RAC going with NFS and I like that!

  2. Hi

    I got following error while configuring RAC using NFS using two base machines.

    /d01/ocr_configuration, entered for the Oracle Cluster is not shared across all the nodes in the cluster

    Do anyone know why I am getting this error?
    and How can I resolve this?

  3. Hi.

    Please ask questions on my forum, not on the blog or in the comments section of my articles.

    Sounds like you NFS setup isn’t correct. You may just need to click the “Next” button again.

  5. Hi.

    Questions in the forum please!

    It’s hard to answer technical stuff in the blog.

    Your situation doesn’t sound like the others. The fact you mention external redundancy makes me think you are doing an installation using ASM, so you can’t be using NFS, which is the subject of this article.

    Please give more details in a forum post, not in these comments.



  6. Hi Tim,

    Thanks for such a wonderful step by step installation procedure for installing RAC on Linux. Can you please giude if same can be implemented on AIX also by using the given steps ? Many thanks in advance.

  7. I don’t have an AIX environment to perform a RAC installation on, so it would be pretty difficult to write an article on it. 🙂
