is a Generation Data Group (GDG)? A1) Generation Data Group is a group of chronologically or functionally related datasets. GDGs are processed periodically, often by adding a new generation, retaining previous generations, and sometimes discarding the oldest generation. Q2) How is a GDG base created? A2) A GDG base is created in the system catalog and keeps track of the generation numbers used for datasets in the group. IDCAMS utility is used to define the GDG base. Q3) What is model dataset label(Model DSCB)? A3) A model dataset label is a pattern for the dataset label created for any dataset named as a part of the GDG group.
