manual failover of iprint service

[Bernhard Muehlbauer]

Hi,

I installed box A (OES2SP1) and configured an
iPrint service on it (created driver store and
print manager). The start of rcnovell-ipsmd and
rcnovell-idsd is ok.

Now I installed box B (OES2SP1).
Is it possible to use the iPrint service of box A
on server B?

If I want to start idsd, I receive the
following error message on box B:
"Starting Novell iPrint DriverStore: ... service not
configured"

Now my question:
can I use the iPrint service of box A on box B and
what must I keep in mind for manual failover if
box A crashes (without! NCS)?

Best regards,
Bernhard

Rainer,

thanks for the tip, but our 2 boxes are located
in 2 SANs (different locations).
Therefore I think, hartbeat can't be a solution for us.

But the approach with rsync to keep the driver
store synced is worth the trouble to test.

Thx
Bernhard

... just for those, who are interested in ...
... reached a sub-ordinate target.
Now I can start the iPrint service on box B.

I've done on box B:
- copied iPrint files and folders from box A to box B:
# scp -r <user>@<ip_address_of_box_a>:/etc/opt/novell/iprint/*
/etc/opt/novell/iprint

# scp -r <user>@<ip_address_of_box_a>:/var/opt/novell/iprint/*
/var/opt/novell/iprint

# cd /etc/opt/novell/iprint/conf
# rm ipsmd.conf
# ln -l PrintManager.Context.ipsmd.conf ipsmd.conf

- then changed the DNS entry for the iPrint server.
The DNS entry for the iPrint server points now to box B.

- start services:
# rcnovell-idsd start => ok
# rcnovell-ipsmd start => ok

Next topic will be not to use "scp" for manual copy but
"rsync" for automatical synchronization.
