How to delete all versions of a GDG?
I know two ways
1) Delete all the known members explicitly like DELETE XYZ.GDG.G101v001
2) Issue a generic delete DELETE XYZ.GDG.*, which is of course fast but risky.

Is there some other safe & reliable excluding the above mentioned 2 ways?

Gore,

You can use an IDCAMS "ALTER GDG" to reset the number of generations to 1 by specifying LIMIT(1). That will automatically delete all but the latest generation.Then delete that one remaining generation.Once again reset the LIMIT count to whatever it was to start with.

The following is a sample JCL for Alter

The following will delete all versions of a GDG keeping the gdg base. userid.mygdg is the gdg base name.
