Setting up dynamic routing for Liberty collectives
The Dynamic Routing feature routes application
requests to all application instances when the application is deployed in multiple collectives.
Previously, when routing to multiple collectives, a particular application could exist in only one
of the collectives.
The Dynamic Routing feature can use rules to route
requests to a smaller set of servers than can handle the request. You can configure rules to permit
the request, reject the request, or redirect the request. If a request is permitted, it can be
configured to load balance across a set of servers or clusters, and to fail over between servers or
clusters.
Before you begin
For the Dynamic Routing function to work, the dynamicRouting-1.0 feature is required in collective controllers only. There is no requirement to upgrade every collective member. Dynamic Routing can be used to route to applications installed in any Liberty server in a collective, including WebSphere® Application Server Network Deployment Liberty, WebSphere Application Server Liberty Core, and WebSphere Application Server (base) Liberty editions.
