You can display and work with generation data groups in
the Remote Systems and z/OS® Projects
views.
You need to be connected to a z/OS system
with generation data group resources.
A
generation data group (GDG) is a group of
related data sets. Each data set within a GDG is called a
generation
data set (GDS) or generation. A
GDG base is a
catalog entry for a GDG, and represents a GDG. Rational® Developer for System z® provides GDG support that enables
you to display and manipulate GDGs and GDSs in the Remote Systems
view. The z/OS Projects and
Remote z/OS Search views enable
you to display and work with GDSs.
All functions available for
data sets are available for GDSs, except the following functions:
- Add a GDG to a subproject
- You can add a GDS in a GDG to a subproject and perform any operations
available for a data set, but you cannot add a GDG as a group to a
subproject.
