  • RE: Enabling LPIM and AWE

    sqlbuddy123 (4/14/2014)


    AWE needs LPIM to be enabled but not vice versa (Ex: 64-bit systems).

    Not true. Once Locked Pages is enabled, memory allocations can be done via the AWE mechanisms,...

    Yeah looks like it was removed.

    No, I linked it wrong.

    If you're going to be around a bit, could you watch that one and this one please?

  • RE: More Memory

    EXEC sp_configure 'AWE Enabled',0

    RECONFIGURE

    It shouldn't be on for a 64-bit process.

    Looks like someone's been playing fast and loose with your config settings.

    My question was Why is this dependency and how can this be justified ?

    It's bit weird bcs they both do different functions and still MS interlinks them.

    No, they don't do different things. MS interlinks them because they're actually the same thing under...

    I'm not sure why MS interlinked both of these settings.

    So is LPIM not a requirement for AWE to function (just a recommendation)?
