    Solaris File sizes


    According to Note 62409.1on Metalink:
    'There is a generic limit on the maximum Oracle datafile size of 4million Oracle data blocks. The exact limit is 4194303 * DB_BLOCK_SIZE.....'

    Solaris size limits are:
    Release Max file-system size Max OS File size
    < Solaris 2.6 1Tb (UFS) 2Gb
    >= Solaris 2.6 1Tb (40 bits) 1Tb

    Hope this helps

    However, even with Solaris 2.6, you must enable LARGEFILES support when you create your filesystem or you will be stuck with 2G with a UFS file system. You will be stuck with a 2G-2K file size if you are using Veritas Filesystem without their LARGEFILES option.

    I personally don't like to create datafiles > 2G anyway. You get into situations where your data is more difficult to distribute. Of course, your mileage may vary....
