data synchronization between two machines

[Maciej Szewczykowski]

Hello,

I've got two b2600 workstations, running HPUX 10. My question is quite simple:
how to synchronize data between them? let's say I have a shared folder on machine A. now, everything what's beeing written into it, should also be stored in a copy of this shared folder existing on machine B.
what I actually mean by the above, is some kind of data replication process.
what can I do to realize my idea?

Thank you in advance,

regards,

matthew

Hi Matthew,

rsync is a toll that allows this

Binaries are available through

There is rsync tool that can do this.
Also NFS is there.

And you can use rdist - built in to HP-UX. I use it to sync some info from one server to another for DR purposes:

I use it like so:

Cron:
# Copy prdadm across to the DR site.
05 01 * * * /app/admin/drp/update-binaries.sh


# cat /app/admin/drp/update-binaries.sh
#! /bin/sh

# Keep the DRP copy of the adm up-to-date.
# Currently the files are in:
#
# /home/prdadm/DR
#
# See the rdist(1M) distfile for a list of exclusions.

DRPDIR=/app/admin/drp
DRPHOST=svr031

HOST=`/usr/bin/uname -n`
PRD=`cmviewcl |grep prddbci |awk '{print $5}'`
if [ "$HOST" = "$PRD" ]
then
mount | grep /home > /dev/null 2>&1
if [ $? -eq 0 ]
then
for vg in `ls -d /dev/vg5* |awk -F/ '{print $3}'`
do
/usr/sbin/vgexport -p -s -v -m /home/prddm/DR/$vg.map /dev/$vg
done
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl /home/prdadm/DR/
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl.full /home/prdadm/DR/
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl.mountonly /home/prdadm/DR/
( su - prdadm -c "rdist -f $DRPDIR/distfile prdadm"; ) 2>&1 |\
tee $DRPDIR/drp.log 2>&1 |\
mailx -s "prdadm DRP rdist output" gwild@mydomain.com
fi



# cat /app/admin/drp/distfile
PRDDR = ( svr031 )

#
# File systems to be copied over to the DR host.
# Don't use -R in install - so as not to remove files on destination host
PRDADM = /home/prdadm

prdadm: ( ${PRDADM} ) -> ( ${PRDDR} )
install -w ;
