    The dll for resorucedb can be found under

  • RE: Clear DMV Stats

    That only works for 2 DMVs - sys.dm_os_latch_stats and sys.dm_os_wait_stats. No other DMV can be cleared using that.

    eg

    DBCC SQLPERF("dm_io_virtual_file_stats" , CLEAR)

    Msg 2526, Level 16, State 12, Line 1

  • RE: Clear DMV Stats

    Other than for the sys.dm_os_wait_stats and sys.dm_os_latch_stats, there's no way.

    Edit: added the other DMV that can be cleared
