I started using the JBOSS recently. I have done clustering of the JBOSS 4.3.0 GA CP02 with load balancer using Apache HTTP server

The load balancing and the clustering is working fine. Today I have configured another two machines with JBOSS in the same subnet and I started them using the following command to avoid the old cluster nodes.

I have started the first cluster with the following command
Cluster A:
Machine 1:
F:\jboss-eap-4.3\jboss-as\bin>run -c node1 -b
Machine 2:
F:\jboss-eap-4.3\jboss-as\bin>run -c node2 -b

Cluster B:
F:\jboss-eap-4.3\jboss-as\bin>run -c node1 -g TS63PERF -b
F:\jboss-eap-4.3\jboss-as\bin>run -c node2 -g TS63PERF -b

I am gettign the following errors.

1. In cluster B command prompt window, after entering the run command the following error is getting displayed and then server is getting started. please find the copy of the command prompt window below.
'-Xdebug' is not recognized as an internal or external command,
operable program or batch file.

I don't see an error, I just see the warning to let you know that it received a message from the other cluster, but that it is ignoring it.

but I think you don't want to see those warnings. So check this out

Hi Mark,
ThanQ very much.. Now the warning message is not coming by giving the run command to start jboss as below

run -c <folder name of the server> -b <hostname or IP address of the machine> -u

I agree. Here's the link:
