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
All Integration Servers in the cluster must be the same version, with the same service packs and fixes applied.
Adapter packages
All adapter packages on one Integration Server should be replicated to all other Integration Servers in the cluster.
Adapter connections
If you configure a connection to the database, 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 InsertSQL 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.
Adapter notifications
If you configure a specific Insert notification, this same adapter notification 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 notification, you might not derive the full benefits of clustering. For example, if a notification executes on only one server, and that server is unavailable, the notification cannot be successfully redirected to another server.
For information about replicating adapter packages, connections, adapter services, and adapter notifications across multiple Integration Servers in a cluster, see Replicating Packages to Integration Servers.
