How to createing new version of GDG with out loosing the
data in preaves GDG version?
Answer Posted / mani
Generations and versions are two different aspects of a GDG.
Generations is which everyone is aware of and its max limit
is 255.
For creating a new generation if we specify gdg base(+1)
then a new generaion would be created and we would be
specifying the dcb parameters for the new generation.
As per my knowledge generally all the gdg versions have the
same dcb parameters but when they change then we go for
specifying a version which means there is a difference in
the attributes of the gdg.
a version is used to continue the same gdg base with a
different set of attributes and it would be specified as
gdg base.v00 and the next would be gdg base.v01.
