EJB workload management behavior
The BeenThere workload management demonstration can be used to view workload management behavior. BeenThere is composed of a servlet and a stateless session EJB. The purpose of BeenThere is to collect information about the execution environment. The servlet retrieves information from the Web container, and the EJB retrieves information from the EJB container. The information retrieved is the server name, Web or EJB container name, and Java process ID.
The BeenThere example can be used to demonstrate workload management behavior for a Web client. We added several EJBs and a J2EE application client to the example so we could more comprehensively demonstrate EJB WLM behavior.
Note We used the topology shown in Figure 6-10 to demonstrate the WLM policies. This topology is not intended to be used as is for a production environment. This topology was used so we could show all the various features of EJB workload management. |

Table 6-2 lists the cluster members weight values we used for our examples:

| EJB1a | 2 |
| EJB1b | 2 |
| EJB2 | 3 |
