Set File or FileGroup to READ_ONLY on a busy system.

    According to Books Online and some testing, I think the answer is probably "NO" but I thought I'd ask just in case someone has an oolie to do it. The question is,

    Is there a way to set a File (NDF, in this case) or FileGroup (I have one file per filegroup in this case) to READ ONLY on a busy system without having to temporarily gain exclusive access to the database by setting the SINGLE_USER mode?

    Thanks folks.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.

    I would imagine not, alter database usually requires an exclusive database lock.
