2003.0. "initial number of ALL-IN-1 users" by YUPPY::DEWINTER (Chocolate?, Yeah!) Tue Dec 22 1992 10:39

    Could somebody (Graham perhaps!!!) explain to me what the importance is 
    of the question during the installation about the HOW MANY ALL-IN-1 USERS
    there will be? Is this for the initial file size allocation, does the 
    customer need to reset this if the number exceeds the one initially set 
    during the installation?
    
    My customer is worried about this!
    
    Thanks for any help

2003.1Only used to set global bufferingIOSG::SHOVEDave Shove -- REO2-G/M6Tue Dec 22 1992 11:059
    It's used to set the global buffering on various system files.
    
    It's done only to improve performance. Nothing will go wrong if the
    number is too low. 
    
    I think the formula used to calculate the global buffering from the
    <number of users> is documented somewhere. (Performance guide?) Given
    that, the customer can simply do $SET FILE/GLOBAL_BUFFER=... to vhange
    the values. ($DIR/FULL shows the currently set values).

    However, set the number too high and the install process may (should??)
    calculate that you've insufficient GLOBAL PAGES to support the
    required number of global buffers - and fail.

    I think the formulae used to calculate the global buffer counts are in
    the Installation Guide.
    
    If not, ask again and I'll dig them out of the code for you.

    PS Dave was certainly better than me to answer this question, since he
    wrote that code, probably unchnaged, since before I took over
    installation in V2.2!

    Describes the suggested global buffer counts on the main shared data
    files and the reason for the settings.
