FreeKB - Route traffic to the application server with the most availability in a dynamic cluster (weight and DWLM)
Route traffic to the application server with the most availability in a dynamic cluster (weight and DWLM)

Home > Search


This assumes you have created a dynamic cluster. Weight is used to prioritize traffic to an application server in a dynamic cluster. In this example, server1 is configured with a weight of "1" and server2 is configured with a weight of "2", which means the more traffic is going to be routed to server 2. Basically, the higher the weight, the more traffic gets routed to the server.

 

You typically wouldn't have different configured weights. Instead, you'll almost always have a weight of 1 for all of the servers in a cluster. Dynamic Workload Management (DWLM) will then dynamically update the runtime weight in real time to route traffic to the application server with the most availability. By default, Dynamic Workload Management is enabled, which you can see by navigating to Servers > Clusters > Dynamic clusters > your cluster > Dynamic workload management (DWLM). This option should be enabled by default.

 

Notice in this example that both server1 and server2 are configured with a weight of "1", but server2 has a runtime weight of 2. This is an example of Dynamic workload management updating an application server in a cluster to have a certain weight based on availability.
