Error while starting managed servers in a cluster

Question

Hi,
          I have Weblogic 8.1.3 deployed on my system. We've have a Ant script that set's up the project domain etc. We have an admin server and two other managed servers which are part of a cluster. I am able to start the admin server and access the admin console without any errors. However when I start any of the managed servers in the cluster, using the following command (startManagedWebLogic.cmd Reactor-1 http://localhost:80 OR startManagedWebLogic.cmd Reactor-2 http://localhost:80)
          I get the error listed below. The same Ant script was used to setup the project on another system and it worked but I haven't been able to set it up on my system.
          The error says that it could be due to servers having duplicate names in the cluster but thats not the case here, the managed servers are named Reactor-1 and 2.
          Also, the IP address being accessed, 192.168.141.50:81 is not my system, its another system on the network. I've done a full text search for the IP address but I've not been able to find it in ANY file under c:\bea.
          Can someone please tell me if I've missed something? I'd appreciated any help with this.
          Thanks
          Ameeth

Answer 1

make sure you use a unique cluster multicast ip address. are you sure that your etc/hosts file has proper entries for localhost?
