Start a listener port
Use this task to start a listener port on an application server, to enable the listeners for message-driven beans associated with the port to retrieve messages.
A listener port defines the association between a connection factory, a destination, and a deployed message-driven bean. See Message-driven beans - listener port components.
A listener is active, that is able to receive messages from a destination, if the deployed message-driven bean, listener port, and message listener service are all started. Although you can start these components in any order, they must all be in a started state before the listener can retrieve messages.
If you set the initial state of a listener port to Started, the listener port is started automatically when a message-driven bean associated with that port is installed. We can also start a listener port manually.
When a listener port is started, the listener manager tries to start the listeners for each message-driven bean associated with the port. If a message-driven bean is stopped, the port is started but the listener is not started, and remains stopped. If you start a message-driven bean, the related listener is started.
Procedure
- Start the admin console.
- If you want the listener for a deployed message-driven bean to be able to receive messages at the port, check that the message-driven bean has been started.
- In the navigation pane, click...
> Server Types > WebSphere application servers ->server_name
> [Communications] Messaging > Message listener service > [Additional Properties] Listener Ports
The Message listener port collection panel is displayed.
- Select the check box for the listener port that you want to start.
- Click Start.
- Save your changes to the master configuration.
