How To Check If Multicast Works On The Network Hosting Mule Cluster

QUESTION

How to check if the multicast works properly on the network hosting Mule Runtime Cluster

ANSWER

If you need to use Multicast for your Mule Runtime Cluster environment and need to troubleshoot the communication issue, please check and ensure the prerequisites are fulfilled.

To check if Multicast works, you can use jgroup.jar and test if the communication works:

1. Download jgroups-4.2.4.Final.jar from javagroups, and save it as jgroups.jar.
2. Run the sender and receiver commands on a different cluster node, and test the communication by typing text messages and see if text messages can be sent and received by each other. 

   Receiver:
   java -cp jgroups.jar org.jgroups.tests.McastReceiverTest -mcast_addr 224.2.2.3 -port 54327
   
   Sender: 
   java -cp jgroups.jar org.jgroups.tests.McastSenderTest -mcast_addr 224.2.2.3 -port 54327
