Viewing and working with generation data groups

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

Before you begin

You must 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. The Developer for z/OS GDG support allows for the display and manipulation of GDGs and GDSs in the Remote Systems view. The z/OS Projects and Remote z/OS Search views allow for displaying and working 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.
Search with a GDG: The Search action is disabled for GDGs so that you cannot search in a GDG. Search results do not include GDGs. Search results 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.
