How to createing new version of GDG with out loosing the data in preaves GDG version?..

Answer / 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.

Answer / guest

Hi,

The question speaks more about VERSION of GDG.

As of now the version will be always zero only.
If you want a versino in you GDG you need to specify,

dd DSN=A.B.D(0001)V01 and other parameters.

or rename the Generation.
