and you are using a load balancer for your Interact runtime servers, you should enable some type of persistence for the load balancer (also known as sticky sessions). If that is not possible, or if you are not using a load balancer, configure the Interact servers session management for a distributed cacheType. If you are using a distributed cache, all the Interact runtime servers must be able to communicate via multicast. You may need to tune your network so that the communication between Interact servers using the same multicast IP address and port does not impede system performance. A load balancer with sticky sessions has better performance than using a distributed cache.
If you have multiple server groups using a distributed cacheType, each should use a unique multicast port. Using both a unique multicast port and address for each server group is better.
