Viewing and working with generation data groups

You can display and work with generation data groups in the Remote Systems and z/OS Projects views.

Before you begin
You need to be connected to a z/OS system with generation data group resources.
About this task
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:
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.
Search with a GDG
The Search action is disabled for GDGs, so that you cannot search in a GDG. Search result do not include GDGs. Search result do include GDSs, and you can perform any operation available for a data set.
Copy a GDG
The Copy action is disabled for GDGs. You cannot copy an entire GDG.
Paste to a GDG
The Paste action is disabled for GDGs. You cannot paste a data set into a GDG.
Rename a GDG
The Rename action is disabled for GDGs. You cannot rename an entire GDG.
See the following topics for more information on displaying and working with GDGs and GDSs.
