Requirements for Each Integration Server in a Cluster
The following table describes the requirements of each Integration Server in a given cluster:
All Integration Servers in a given cluster must have identical...
For example...
Integration Server versions
One Integration Server in the cluster cannot be version 7.1 and another Integration Server in the cluster be version 7.1.2 - all servers must be the same version, with the same fixes (updates) and service packs applied.
HL7 Module packages
All HL7 Module packages on one Integration Server should be replicated to all other Integration Servers in the cluster.
HL7 Module versions
All HL7 Modules must be the same version, with the same fixes (updates) and service packs applied.
HL7 Module services
If you configure a specific HL7 Module service, this same service must appear on all servers in the cluster so that any Integration Server in the cluster can handle the request identically.
If you allow different Integration Servers to contain different services, you might not derive the full benefits of clustering. For example, if a client requests a service that resides on only one server, and that server is unavailable, the request cannot be successfully redirected to another server.
