I used mkisofs and cdrecord under Linux. The AWS files were compressed and stored along with companion files that contain the original DCB and allocation characteristics. A postgresql index kept track of MVS datasets and the CD serials. It was an interesting project, and I learned more about bash than I ever wanted to. Last time I touched it I got a wild hair and started to recode the bash stuff in SBCL Lisp. Then I thought it would be useful to have an inotify library and worked on that. Time ran out on me before I got the Lisp code running to my satisfaction. As I said, it was proof-of-concept more than anything else. Lots of things I'd do to it: I would have liked to operate a CD changer - write on one drive, read from another. I'd have liked a web interface to the server. I'd have liked to do encryption. > Has mkisofs been ported to z/OS? Hmmmm, unknown. In my implementation it was on the CD server. The bash script would accumulate datasets until it reached a threshold, then create the iso. (But the server could be told to cut the CD regardless of the current queue size.) > Which DSORGs will this handle? PS, of course. What about PDS, > PDSE, Program Objects, HFS, zFS, *SDS VSAM? I only did sequential datasets. > What AWS utilities do you recommend? I used AWSSL, which had some limitations three years ago. I remember that it didn't handle spanned records, so I always told AWSSL that the dataset to be offloaded was RECFM=U. As I mentioned above, when I transport the AWS dataset it is paired with a characteristics dataset that contained the real DCB information. -- David Andrews A.
