Integration Server versions

All Integration Servers within the cluster must be identical. Every server must be the same version and have the same service packs and fixes (updates) applied. For example, one Integration Server cannot be version 8.0 and another Integration Server version 8.2.

Additionally, all Integration Servers should use the same clustering implementation, either Coherence or Terracotta.

FIX Module packages

All FIX Module packages on one Integration Server should be replicated to all other Integration Servers in the cluster.

FIX Module versions

All FIX Module servers within the cluster must be identical. They must all be the same version, with the same fixes (updates) applied.

FIX Module services

If you configure a specific FIX Module service, this same service must be installed on all servers in the cluster so that any Integration Server in the cluster can handle requests identically.
