Can you get Netezza to dump to the "file" /dev/stdout, and then do
ssh user at netezzahost 'netezza --dump-to=/dev/stdout' | ssh user at bigiron
Similarly, if you're logged-in to netezza host:
netezza --dump-to=/dev/stdout | ssh user at bigiron 'oracle --read-from=/dev/stdin'
You can add '-C' after 'ssh' to add compression to the communication, too,
if you wanted.
You can't cheat an honest man. Never give a sucker an even break or
smarten up a chump.
