Configuring the Forwarding Mode
A cluster gateway maintains a subscription list that identifies the types of documents the remote cluster wants to receive. This subscription list tells the cluster gateway which documents it must forward to the remote cluster. The forwarding mode determines how the cluster gateway populates and maintains this subscription list.
*In dynamic forwarding mode, a cluster gateway maintains the subscription list for a remote cluster based on subscription events that the remote cluster gateway issues when clients in its cluster add and drop subscriptions to a document type that the clusters share. Broker Servers version 6.5 and earlier use only dynamic forwarding mode.
*In static forwarding mode, a cluster gateway automatically populates the subscription list based on the document types that the cluster gateway is permitted to forward to the remote cluster. Static forwarding mode is the default mode in Broker Servers version 6.5 and later.
In static mode, it is important to configure the allow-forward permissions carefully. If the list includes document types for which there are no actual subscribers in the remote cluster, those documents will be forwarded to the remote cluster unnecessarily, wasting processing time, queue space, and network bandwidth. For information about configuring the allow-forward permissions, see Exchanging Document Types across a Cluster Gateway.
If you are running Broker Server that supports both modes, we recommend that you use static forwarding mode (the default). This mode is less prone to subscription propagation failures related to network outages and timing factors.
*To view or configure the forwarding mode
1. In My webMethods: Messaging > Broker Clusters > Cluster Gateways.
2. Click Details for the cluster gateway whose forwarding option you want to view or configure.
3. On the Configuration tab, select or clear the Static Gateway Forwarding check box.
If the cluster gateway is running on a Broker Server that does not support static cluster gateway forwarding, you will not be able to enable this option.
