Copying Datasets between systems

there are various options to copy files e.g. from a test-plex to a production-plex. we have a few shared volumes and catalogs to copy.

i´m searching for other solutions. i know there are file transfer products that can do this. i do not want to use such a solution.
what about ftp + rexx? is anybody using a self-written utility to copy with ftp in an automated fashion?

what are you using? can you give me a few ideas please?

how can i copy a vsam-dataset from one plex to another one without shared dasd? i think the only option is to create a dfdss dump, copy the sequential file and restore it on the target-system.

thanks

with shared dasd... depends what is shared...
if the dasd volume shared are the final destination of the datasets and proper catalog sharing
a DFDSS copy/rename will do the task nicely

for any other setup local/remote
DFDSS dump
<move things to the other system> using
- shared work dasd
- FTP ( or any other file transmission tool )
- real TAPES
DFDSS restore/rename
are the obvious choices
the smart filtering capabilities of DFDSS make rexx a useless overhead

The last time I tried a binary FTP copy of a DF/DSS dump, it could not be restored at the target system.

Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaargh, my brain has gone.

What is the IBM program used for compressing dumps.

I have fed a DF/dss output through this program, ftp'd to another system, and the unblocked and used the output for a DF/dss restore, and it all worked fine.

I think, but can not be 100% certain that I did specify recfm VB for the DF/dss output.

Someone put me out of my misery and tell me the program name, please.

TRSMAIN is what I wanted

expat: TRSMAIN has been replaced by AMATERSE. I haven't done enough with AMATERSE to be sure what the differences are.

I guess that amaterse is the <official> <thing> and is now part of zOS

terse(trsmain) was an unofficial tool used to compress dumps sent to the IBM software support center .

here is the link to the whole shebang
techsupport.services.ibm.com/390/trsmain.html

as an add on to the initial post
to avoid issues with dfdss, the best thing is to explicitly define the disk blksize as 27998
seen it, done it, withot any side effects

When terse was officially delivered as a part of DFSMS its name changed to AMATERSE, TRSMAIN was kept as an alias of AMATERSE for compatability reasons. Basically it is the same program it has just been re-branded.
