Applies to:Oracle Coherence - Version 220.127.116.11.0 and later
Information in this document applies to any platform.
Coherence uses TCMP, a clustered IP-based protocol, for server discovery, cluster management, service provisioning and data transmission. To ensure true scalability, the TCMP protocol is completely asynchronous, meaning that communication is never blocking, even when many threads on a server are communicating at the same time. Further, the asynchronous nature also means that the latency of the network (for example, on a routed network between two different sites) does not affect cluster throughput, although it affects the speed of certain operations. TCMP uses a combination of UDP/IP multicast, UDP/IP unicast and TCP/IP.
The machines used to host the coherence members are possible configured with IPv4 and IPv6 support and else disabled one of them on the NICs those are used in the coherence.localhost or coherence.wka configuration of the cluster. Therefore, the below question raises sometimes from the customers.
Is it allowed and recommended to use mixed use of IPv4 and IPv6 enabled for the JVMs of the coherence cluster?
