3115.0. "IAD very slow" by ANGLIN::HARRISA (Bicycles need seat belts) Fri Aug 06 1993 23:49

    ALL-IN-1 3.0-1, VMS 5.5-2
    
    This is a 3-node cluster. When trying to do IAD, and leaving the system
    field blank, it takes a very long time for anything to be returned.
    There are 2700 users on the system. Of course when IAD is done in the
    MANAGER account, it just flys and returns all 2815 drawers in seconds.
    
    is this taking a long time for the users because of the size of the
    userbase?  are there nything system parameters that i should have the
    VMS people look at to adjust.
    
    its been 10 minutes now that the IAD has been processing and nothing
    has been displayed yet.  if this is "normal" that's ok, so long as i
    can give the customer an answer.
    
    thanks - ann

3115.1"Normal" behaviour ...AIMTEC::VOLLER_IGordon (T) Gopher for PresidentSat Aug 07 1993 01:4721
    Ann,
    
    I think what you are seeing is "normal".
    
    When a regular user uses IAD to determine which drawers they have
    access to, the FCS needs to check each drawer's ACCESS.DAT to see
    whether they have access or not. Ie, PARTITION.DAT is searched 
    sequentially for each drawer and only those that the user has access 
    to are displayed.
    
    When a MANAGER does the same thing, a check shows that this user
    has the OAFC$SYSMAN identifier and the FCS just returns the drawer
    name (no further access checking).
    
    Suggest to your customer that a check by USERNAME will be very much
    more efficient.
    
    Cheers,
    
    Iain.
