Regarding software products, can I live without tape? Yes, definitely.
Would I like it? No.
I use tape as an installation medium only for ServerPacs (z/OS and DB2,
and CICS, and NCP in the past).
Other stuff like IBM CBPDO or ISV products come to me via Internet or
via DVD (for ISV's which do not offer Internet download).
Now, why I use tapes for ServerPac.
A couple of reasons:
* Software download is cumbersome, especially for big downloads. I want
to have packing list, MEMOEXT, basic documentation (Installation
Directiories) and some "ISO data". It is much easier to get in in the
box. Note, the same advantage exists for non-tape physical medium (DVD).
Note, the bigger problem exists for non-z/OS code add-ons like
documentation or ISO images (CD, DVD).
* SMP/E and "pre-SMP/E" procedures for software installation. You have
to upload (or download directly) the package to the host - that mean
huge HFS container. Then you have to unpack it (can be combined with
next step), RECEIVE it, then start SMP/E installation. A lot of DASD
space is consumed.
Compare it to ServerPac procedure: two jobs. ALLOCDS creates empty
datasets, next job reads the tape(s) and copies fills the libraries. No
DASD needed for "tape content".
* Procedures. Both CBPDO and ServerPac assume tape as medium.
* Lack of scripts. When I get DVD or Internet-downloaded files I have to
upload it to the host manually. It would be nice to insert first DVD
into the drive run some application - some ftp frontend, choose some
simple options like HFS directory, IP (kept for next uses) and start
copying+restoring.

We see a low and decreasing percentage of our software orders on tape.
If you are still using tape for z/OS platform software delivery (that
is, any product that runs on z/OS, not just z/OS itself), I'd like to
hear from you to understand:
- Why you choose tape for software delivery
- Whether you can use one of the alternatives, DVD or Internet, and if
not, why.
Feel free to either post or send me a note directly. If there's
general interest I can aggregate the responses (both public and
private) and post the result (with any identifying information removed).
Note that *NO* decision has yet been made to set an actual date for
removing tape as a delivery medium. However, it's clear which way the
wind blows, and if you really, really need tape we need to hear from you.
Thanks,
