G'day, folks. We need to move about 46GB of oracle files -
distribution plus the database - across the web to another
host, to be installed on the secondary host as a copy of
our oracle server. We've been trying making tapes with
vdump piped to an rsh to a tape host (DLT), and then overnighting
the tapes, but have met with repeated problems with the
tapes themselves, making it a painful process.
We've also tried tars, dds, etc. directly to the remote
machine, but the transfer rate is painful - on the order of 431KB/sec.
We have T3 access to the net on both ends and 100Mbit from the servers
to the routers, but we just aren't able to get the speed up
to where it is reasonable to move this much data while having the
database in a hot backup mode. Nonetheless, given the problems
with the tapes, I'm wondering if we are missing something.
Has anyone done anything like this and achieved decent speeds?
What techniques did you use? Did you use compression? It seems that
with those sparsely populated database files, compression would help,
but I don't know any good ways to do it???
Many TIA for any advice you can send. This is on Tru64 v4.0F,
servers involved are GS140s.
Regards,
Judith Reed
