Integration Server versions

One Integration Server in the cluster cannot be version 6.5 and another Integration Server in the cluster be version 8.0 - all servers must be the same version, with the same service packs and fixes (updates) applied.

Adapter packages

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

Adapter versions

In the cluster, all Remedy Adapters must be the same version, with the same fixes (updates) applied.

Adapter connections

If you configure a connection to the AR System Server, this connection must appear on all servers in the cluster so that any Integration Server in the cluster can handle a given request identically.

If you plan to use connection pools in a clustered environment, see Considerations When Configuring Connections with Connection Pooling Enabled.

Adapter services

If you configure a specific adapter 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.
