Thank you so much for your help.

One more question.

Concerning your statement:

    >Clients will cope with some of the
     >VLDB servers going away from the client perspective *as long as* the Ubik
     >master is one of the ones that doesn't go a way.

Does this mean that I need to keep my current Ubik master ( the server running 
with the lowest ip), around permanantly?
If so should the network IP address ranges for my other new DB servers be 
higher than the current Ubik master?

Thanks,

Greg

You may or may not be able to tell.  For example, Stanford's are on three
different subnets.  We disperse them physically around our campus.  The
VLDB doesn't require much in the way of bandwidth; if you have working
network, you're unlikely to notice.
