Answer 1

          You need an IP for every instance you want to run regardless
          of managed or admin.
          So from the sounds of it, you need 3.
          You don't need separate NIC cards, only IP's.
          These can be virtual.
          Here is a for example. Call Box X ren call Box Y stimpy
          This will be the machine names in the admin console.
          Set up Servers in the console.
          There should be one called myserver (unless you changed it)
          DO NOT CLONE!!! there appears to be a bug.
          Call server 1 app1 and server 2 app2.
          app1 is box x (ren)
          app2 is box y (stimpy)
          Assign listen address ips (these will be the machine ip's for
          this, real or virtual)
          listen port, keep it 7001. all three will run on this.
          Also set up a cluster in the machine console.
          Assgin the cluster address as ren,stimpy or whatever the real
          mahcine names are.
          set multicast (237.0.0.1) works.
          There are limits for this, I am unsure what they are exactly (range)
          that is it
          startManagedWebLogic.cmd app1 http://10.255.2.98:7001
          startManagedWebLogic.cmd app2 http://10.255.2.98:7001
          where 10.255.2.98 is the admin server.
          wala, you are running a cluster.
          see if that all works.
          later,
