    One last question. I read that when executing the enable RCS command that there can't be any other connections or transactions open in that database.

    Correct

    Also, btw, turn on IFI unless for security reasons you can't. That will dramatically speed up data file growth on all databases, including system ones.

    What is IFI?

    If you can do w/o the direct DupesCount, you can also use an EXISTS check:

  • RE: Data file unused space issue

    For a 500GB db, those are modest amounts of space to be available/reserved.

    I think trying to shrink that db would do far more harm than good.

    Change all filegrowth to fixed amounts rather than %s. That is, change anything like "10%" to a fixed amount instead, such as "1MB".

    You may or may not need partitioning.
