Deleting a multiple VSAM files with different HLQs

Hi!
I have to delete some 1000 VSAM files which have actually over-allocated. The files have different HLQs. I think i can take the list of the VSAM files as input in a file and then delete these files either using a COBOL program or using a JCL. But i dont know how to delete it using either of them!1 Is there a possibility of doing so?? Your help would be greatly appreciated..

Do you want to delete every VSAM file for a given HLQ, or only selected VSAM files ?

I want to delete only selected VSAM files.

How will you know which files are to be deleted and which ones retained

Well, i have to delete all the files which are over-allocated. I have the list, and almost none of the files fall into certain criteria like putting them A.A.B.* or something like that. Hence, i think i can have a PS containing all these VSAM files and delete them one by one either through JCl or by a small program. But then is there a way to do so?? Or is there any other alternative approach??

Hello,

You could read the file containing the names of the datasets to delete and then generate the jcl and control statements to delete them.

One easy way would be to generate IDCAMS steps to delete the files.

A couple of suggestions

If your shop has FDR Compactor from Innovation Data Processing, that will release unused VSAM space.

If your SMS environment is set up with some thought then VSAM free space release is available too.
