It seems that while the pethN and ethN in a dom0 can be set to support jumbo frames the bridge that connects them cannot. Some symptoms are ssh works but scp does not, pings the size flag set to overflow the standard 1500 mtu fail, ifconfig xenbr0 mtu 9000 fails. This was tested with xen 3.1 and rhel5.
When moving bulk data from postgres to monetdb you can use the psql \copy directive and the mclient copy like so:
psql: \copy gftp_packets to 'my dump file' with csv mclient: copy into gram_packets from 'my dump file' delimiters ',','\n' ;
Booleans don't work, but a little python will fix it up:
fin = open('my dump file', 'r') fout = open('my new dump file', 'w') falserep = (x.replace(',f,',',0,') for x in fin) truerep = (x.replace(',t,',',1,') for x in falserep) for line in truerep: fout.write(line)
I was too lazy to fix the problem with successive booleans, so I just rinsed and repeated until all the t's and f's were 0's and 1's.
