Information in this document applies to any platform.
Coherence geographically spawned (stretched between the data centers) data-grid communications in the WAN is a latency prone environment. For an example, a customer is using stretch cluster for a weblogic domain. Coherence is part of their Weblogic-OAM instances. All nodes are identical in configuration. The nodes between two data-centers are in different VLAN's. In the testing (datagram-test or //iperf, the latency is around ~106ms. Customer wants to know how to ensure better communications.
