How to ftp the cbttape from cbttape.org


 

Does anyone have a sample of how to download the latest CBTTAPE to a version of z/OS. I am trying to follow the example from the CBT website, and, having never used the z/OS FTP facility, I'm at a loss. I have everything set up on my z/OS system, but I'm falling deeper down a rabbit hole. I've downloaded the files before, using my PC as intermediate storage and then sending the file to z/OS using my 3270 emulator (VISTA3270), but that seems like an added unnecessary step.
?
Thanks...
Frank

Don't you mean upload?

FTPing to/from z/OS is just like FTPing to/from anywhere else. The only difference is, because it's z/OS, its file system structure is quite different from most other FTP sites you've probably interacted with before.

With most other FTP site, their file system is likely identical to the way files are organized on most personal computers: files within a hierarchy of directories (e.g. /foo/bar/file). On z/OS however, they're organized by a hierarchy of period separated dataset names.

Because of that, the FTP client you are using needs to know how to properly tell the z/OS FTP server where the given file should be placed. It needs to "know" about z/OS's file system structure.

I do FTP to/from z/OS from my Windows system all the time with FileZilla (which thankfully *does* understand and support "MVS" FTP servers. I can help you with FileZilla if you need it.

(Urk!) Okay. I lied. I've never used z/OS's FTP *client* before. I apologize for the misunderstanding.

If I understand you correctly, you are wanting to use z/OS's FTP *client* to connect to some FTP web site out there on the internet (in your case, the CBTTAPE site) and DOWNLOAD one or more of their files directly to your z/OS system! Yes?

Sorry. Can't help you there. I've never done that in my life. :(

I always download the file to my PC, and then UPLOAD it from my PC to z/OS.

I didn't even know z/OS *had* an FTP client! Where is it? How do I get to it? How do I run it? Or is it something lame like a batch job you have to run?

I'm with you, Frank! I too would very much like to learn how to do that!

Folks? Anyone out there know how to do this? Any helpful web page or IBM manual you could point us to?

Sorry for wasting your time with this unhelpful reply, Frank. :(

By far the best way to use CBT is via the CBT dialog available on file 43 of the CBTTAPE.ORG files.?
?
It allows you to browse and download (via FTP internally) directly to your z/OS system from the ISPF interface panels.? It keeps track of when files change on the site and you can update your local copy and also keep the old version around.?
?
It's actually a really simple and great way to work with the files.? I have been using it for a couple years now and while occasionally I still download things from CBT to my PC, I very rarely use that copy for anything except viewing it on the PC, it's much easier to just bring up the rexx exec on the mainframe and get the files directly.? You can also view data about what's inside each of the files, but I honestly don't tend to use that part very much at all.
?
It appears to be exactly what you are looking for because it goes directly from the CBTTAPE.ORG site to your z/OS instance.? Give it a try, you'll like it and likely never think about downloading a single file and then uploading it to your z/OS again.

Thanks, Frank! Much appreciated!

Now all I have to do is find the time to give it a try and play around with it. :)

(which at the rate I'm going won't be until sometime around the heat death of the universe.)
