How To Verify That Peer-To-Peer UDP Communication Does Work Well Between Machines Coherence Cluster Members Are Supposed To Be Running On (Doc ID 1936575.1)

Last updated on JULY 25, 2018

Applies to:

Oracle Coherence - Version 3.6.0 and later
Information in this document applies to any platform.

Goal

This document explains by example how to use the datagram test utility shipping with Coherence by demonstrating some problems that might be uncovered by the tests.

By default Coherence uses UDP unicast for sending data between cluster member to cluster member (peer-to-peer).

It is essential that UDP communication works with a degree of reliability and throughput that must be expected from the infrastructure it is running on, compute nodes, NICs, network switches, routers and bridges.

Further details on how to use the Coherence datagram test utility can be found in the Coherence documentation: Oracle Fusion Middleware Administering Oracle Coherence, 12c (12.1.3), 3 Performing a Network Performance Test
