Hi,

The customer wants to reduce LIMIT parameter on GDGs used in production jobs to save DASD cost. We have 328 jobs using GDGs but don't know the LIMIT on each one of them.

Of course, we can use File-Aid or LISTCAT if it is one or two GDGs but here the volume is large.

Is there any way to figure out the LIMIT parameter of 1000+ GDGs by JCL way or something else?

Please help.

TIA.

Kolusu,

Thanks for the help. I have actually found that solution before raising my question in the forum. Since, I have 1000+ GDGs to do, I was not getting how to accommodate them in LISTCAT command. All my GDGs are having different naming conventions and don't start in a standard way. Also, the GDGs we have are not having same number of nodes (qualifiers). Few have three, few have four and few have seven.

Please suggest.

mf_user,

Just include all the GDG base names individual as follows in step010

If the aim of the exercise is to retain the generations but not on DASD then the best approach would be to discuss your requirement with the people responsible for the DFSMS subsystem. A very simple change will automatically migrate the unwanted generations every day, and will not need any extra manipulation for new dataset names that may occur.
