Hi Krishna,
 Ok if I understand this correctly are you saying that I only need the
server spec file on server1?  Or do I need one on all servers?
And I would need a slightly different client spec file on each client?
If so, is there a way to write the client spec file so that the same
client spec file could be copied to each node?

Gerry
