Administration of service and endpoint listeners
The administration function of the product is enhanced to support service and endpoint listeners. We can use MBeans such as EndpointManager and the EndpointCentralManager to invoke service and endpoint listeners.
After an application containing a web service is installed, you want to verify that the service is installed correctly. You also want to monitor its service listener state, and update the listener state as needed to control the throughput. One option is to use the collection view of service providers in the administrative console of the product to locate the service provider of interest and observe its listener state.
If you do not want the listener state, then select the service and choose to start or stop the service listener. As the system starts or stops the service listener, the status indicator for the service is updated to show that it is started or stopped. This scenario helps you to throttle back traffic to a specific service as needed but leaves the containing application and other services in the application running. See service providers at the cell level . We can also reference service providers at the application level .
We can only start or stop the service listener .
Another option is to use MBeans. With MBeans, you can invoke the startListener or stopListener operations in the EndpointCentralManager MBean or EndpointManager MBean to start or stop the listener service. The administrative console option does not expose the function of starting or stopping the listening state of a specific endpoint in a service. However, the MBeans option provides this capability. We can use scripting to invoke the MBean operations to start or stop the endpoint listener.
EndpointCentralManager MBean
There is an EndpointCentralManager MBean instance in the dmgr, AdminAgent, and stand-alone server. The EndpointCentralManager MBean provides the administrative convenience to start and stop the service or endpoint listeners across all the deployment targets such as the cluster members in a cluster. You do not have to know the target servers for the service application.
EndpointManager MBean
There is an EndpointManager MBean instance for each web services application module in a server. This MBean instance is created when the application module is started. The MBean instance is deleted when the module is stopped. The MBean provides the start and stop operations to change the service and endpoint listener state. The MBean can also send a Java Management Extension (JMX) notification whenever the listener state has changed.
