The GDKUTIL utility does allow an Upload of something with RECFM=U.
This was done at the behest of a customer that was using ftp to put SMF data
out for processing by the SAS tool. Apparently, they are able to decipher the
RDW records resulting from uploading a RECFM=VBS as a RECFM=U.
I would be slightly surprised if SAS can't read VB records properly
formatted with the RDW. RECFM U was a workaround for the problem where
FTP stripped out the RDW. So GDKUTIL seems to be reproducing the
brokenness of FTP, then providing the same workaround as a feature.
It would be preferable if it retained the RDW in VB records by default.
GDKUTIL seems new enough that the default could be changed without too
much impact. I doubt there is anyone using variable length binary
transfers currently who needs the data without the RDW. (However there
might be people uploading data who haven't discovered the resulting data
is unusable.)
I have been working with SMF data myself for many years, and this
problem with FTP causes a LOT of customer confusion and frustration.
