How To Verify that Multicast Communication Works Correctly Between Machines the Coherence Cluster Members Are Running On
Last updated on MARCH 13, 2017
Applies to:Oracle Coherence - Version 3.4.0 and later
Information in this document applies to any platform.
This document explains by example how to use the multicast test utility shipping with Coherence.
By default Coherence uses multicast communication for messages supposed to be sent to more than 25% of the cluster members.
Coherence switches off multicast communication if well-known addresses (WKAs) had been configured.
So, it is not required to run the multicast test if well-known addresses are going to be used in the target environment.
Further details about the Coherence multicast test utility and about troubleshooting multicast issues can be found at: Oracle Fusion Middleware Administering Oracle Coherence, 12c (12.1.3), 4 Performing a Multicast Connectivity Test
