Each Integration Server in the cluster should contain an identical set of packages that you define using SWIFT Module. To ensure consistency, make sure that you create all packages on one server and replicate these packages to the other servers. If you allow different servers to contain different packages, you will not derive the full benefits of clustering. For example, if a Trading Networks processing rule requests a service that resides in only one server, and that server is unavailable, the request cannot be redirected to another server.
