Re: PKZIP for mainframe

[Skip Robinson]

An update to my own post. Tom Brennan found this on the web:

"In 2002, PKWARE purchased Ascent Solutions, Inc. (ASi), which was founded
in 1993 and had grown to become the leading provider of PKZIP for mid-range
and mainframe systems such as AS400 and MVS. With this acquisition, PKWARE
is now positioned to provide a complete portfolio of PKZIP-enabled secure
data compression solutions across all major enterprise platforms."

The product we trialed is probably now PKWARE. Simplifies the choices, I
guess...

We use the Zip/390 from DATA21 Software, is much cheaper than PKZIP.

Re: PKZIP for mainframe

[Knutson, Sam]

I just posted this under a different subject but there are many choices.
These are just the ones I have at hand and I am sure there are others.
I don't think anyone has mentioned SLiKZiP, ZIP/390, or MegaCryption all
viable alternatives to PKWARE.  Some customers have found the pricing on
PKZIP to be an issue.

Freeware 

Info-Zip

http://www.info-zip.org/pub/infozip/Zip.html#MVS

Mini-Zip included in REVIEW convenience pack

http://www.prycroft6.com.au/REVIEW/index.html

See PDS members MINIUNZ & MINIZIP and minizip.txt note in documentation.


Commercial

SLiKZiP by ASE

http://www.slikzip.com/

ZIP/390 by Data21

http://www.data21.com/products/zip/reports.asp?zip=390

MegaCryption/MVS offers zip and gzip compression features starting with
version 5.3

http://www.megacryption.cc/

SecureZIP and PKZIP by PKWARE

Thanks for all the replies, public and private. I didn't notice the thread

It is.

A Unix platform is probably using tar and gzip, which should work just
fine on your end. Unless you need the extra functionality, Info-Zip is
the obvious alternative to gzip. I don't know which of the two is
faster.

If it's gzipped or zipped but not tarred (there's some, but little, point
in tarring a sequential file) a Rexx script can pipe the output of gunzip
or funzip (the latter from info-ZIP) directly into IEBGENER with SYSUT2
allocated to a Classic data set.  This removes the need for an HFS
intermediate file.

Can that invocation of IEBGENER be done from REXX called under a shell, and
if so is "address TSO" required first?  Or can this only be accomplished
from TSO/batch REXX?

Thanks for helping cure my ignorance.

Yes; no; not necessarily.  There's a splendid example of exactly this
in:

   and dynamic output

Use "address SYSCALL 'pipe stem.'" to create the pipe;  "address
SYSCALL 'spawnp funzip ...'" to execute the unzip process.

Re: PKZIP for mainframe

[Schiradin,Roland HG-Dir itb-db/dc]

Does somebody know I re-port GZIP from Harald with some enhancement.
You can find the source at www.cbttape.org. It's called GZIP/390 

Well it was years ago and so far I know of two clients using them in production.

If I get payed I'll verify if I can imrpove the coding and also provide 
one-day support. So far the two clients haven't request this so it seems
the freewar at cbttape works fine for them or they made some changed outside the
GNU license stuff. 

Regards Roland

You're welcome.  Several years ago, I wrote the code in a pair of
Rexx filters, ReadDD and WriteDD, and placed them on a freenet web
site.  Apparently they're still there:

   Linkname: readDD.zip
URL: http://www.nyx.net/~pgilmart/readDD.zip

Since then, I've rarely used the filters as such, but often used
the technique inline in other EXECs.
