    Unanswered: Are Raw devices still required for RAC ?

    On Windows and AIX servers,
    does Oracle 9I clustering still require using Raw Devices
    instead of traditional filesystem I/O ?

    Thank you for your help!

    After a lot of searching, I found that oracle cluster file system (OCFS)
    is supported by Linux and Windows since late 2002...

    but I can't find such references anywhere for AIX,
    so I assume AIX still only allows Raw devices.

    If anyone knows, please reply.

    Thank you!!

    I was told that veritas would port the veritas cluster filesystem to aix later this year. Currently it is only available on Solaris.

    You have that on Linux and Solaris. Windows clustering is available as well. Not yet for AIX.

    The best is the Linux one. Two more vendors are offering file cluster systems except Oracle, so you have choice. I believe the Oracle's one is even open source.


    Hope that helps,
