Re: Sending huge file between machines on same subnet

These are very welcome!

What I am trying to do is sending the entire DOMINO data folder in the IFS
to a new machine as the Notes-Domino application is going to be migrated.

So... does *everything* you need to transfer *normally* reside in the
IFS and outside of QSYS.LIB?

The old machine is running on V7R1 end is an 8202-E4D.

Very helpful to know.

I have identified one specific subfolder in the IFS structure I am saving
where there is an enormous amount of data. I am thinking of transferring
that piece separately and possibly piecemeal.

Gavin seems to have provided a good suggestion, which reflects actual
experience in a similar situation as you, so if that works for you, I
suspect that is probably the best, or at the very least, good enough.

I don't speak from direct experience having to transfer that volume of
data, but I have some ideas to throw out there:

If what you are transferring is all stream files, and you are only
using a save file for convenience and compression, then if Gavin's or
other people's suggestions don't work, I think it is worth considering
creating a stream file archive instead of a save file.

The system includes basic compression and archiving utilities (the
commands "compress" and "tar", or the zip-compatible "jar"). I don't
know if these produce a better package for transporting than a save
file, but they might.

An even better archive utility (in terms of compression ratio) is
7-Zip, which is available from IBM for free as an RPM on newer systems
(7.2+), but also for older systems thanks to Scott Klement:

https://www.scottklement.com/p7zip/

So, if you go that route, you would use Scott's version to archive on
the old machine and IBM's (or Scott's) to extract on the new.

Especially if you are going to manually transfer stream files
separately and piecemeal, it is worth using some kind of
stream-file-based archiver.
