Every webMethods Integration Server in the cluster should contain an identical set of packages that you define using the Adapter for JMS; that is, you should replicate the Adapter for JMS services and the connections they use. You do not replicate the polling notifications.

To ensure consistency, we recommend that you create all packages on one server, and replicate them to the other servers. If you allow different servers to contain different services, you might not derive the full benefits of clustering. For example, if a client requests a service that resides in only one server, and that server is unavailable, the request cannot be successfully redirected to another server.

For information about replicating packages, see the webMethods Integration Server Administrator’s Guide for your release.
