    Hello All:

    Does anyone have anything for calculating how much disk space would be
    needed for an unload and reload of a CAS 3.0 Data Base? The calculations
    almost
    seem impossible except for a MIT Trained Mathematician.

    I would not think that CAS would be any different than an ordinary IDMS
    database - you just have to deal with each database area as its own
    entity. The generic formula for sizing for an unload/reload is

    NewSpace = ( CurrentSpace * PercentFullNow ) / PercentFullDesired

    NewSpace and CurrentSpace can be in tracks, bytes, GB, same-sized-pages,
    as long as both are in the same unit.

    "Bill,

    Are you talking about the CAS sizing program that took in functional
    information and spit out the area sizes?
