What is a GDG? How is it referenced? How is it defined? What
is a MODELDSCB?
Answer Posted / krithiga hari
Generation Data Groups or GDGs are a group of data sets
which are related to each other chronologically and
functionally.
Generation 0 references the current generation.
Generation -1 references the generation just before the
current generation.
Generation +1 references the generation just after the
current generation.
MODELDSCB is a model prototype which contains the
specification for the DCB subparameters for all data sets
that will belong to the GDG. Each time a data set belonging
to that GDG is created, it will use the DCB subparameters
specified in the model prototype.
