Oracle Coherence - Version 3.6.0 and later
Oracle Communications Order and Service Management - Version 7.3.5.0.0 to 7.3.5.0.0 [Release 7.3.0]
Information in this document applies to any platform.

Goal

Coherence 3.6 introduced a new feature implementing death detection on machine level called "IP Monitor".  For a description of this feature please refer to <Note:1526745.1>, What Is The Purpose Of IpMonitor In A Coherence Cluster?

Coherence ships with a simple test utility class:

com.tangosol.net.Ping

which allows to test if the target machines had been setup correctly, so Coherence can use the IP Monitor feature.

This document explains how to use com.tangosol.net.Ping to verify that the target machines have been setup correctly and uses an example of an environment with a problem to demonstrate the type of troubleshooting steps that should be taken.
