Integration Server versions

One Integration Server in the cluster cannot be version 7.1 and another Integration Server in the cluster be version 7.1.1-all servers must be the same version, with the same service packs and fixes (updates) applied.

ebXML Module packages

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

ebXML Module versions

One Integration Server in the cluster cannot have ebXML Module Version 7.1 SP1 and another Integration Server in the cluster have ebXML Module Version 6.0.1-all ebXML Module must be the same version, with the same fixes (updates) applied.

ebXML Module services

If you configure a specific ebXML Module service, this same adapter 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.
