Manage the message endpoint lifecycle using wsadmin.sh

Use the Jython scripting language to manage your message endpoints with the wsadmin tool. Use this topic to query the configuration for message endpoint properties, and to deactivate or reactivate a message endpoint.

The Java EE Connector Architecture (JCA) allows the application server to link inbound requests from messaging resource adapters to message endpoints. The message endpoint managed bean (MBean) is a Java Management Extensions (JMX) framework MBean that the application server associates with a message endpoint instance.

Use this topic to manage situations where messaging providers fail to deliver messages to their intended destinations. For example, a provider might fail to deliver messages to a message endpoint when its underlying Message Driven Bean attempts to commit transactions against a database server that is not responding. To troubleshoot the problem, use the wsadmin tool to temporarily disable the message endpoint from handling messages. After troubleshooting the issue, use the wsadmin tool to reactivate the message endpoint.

Also use this topic if we are connecting to IBM MQ and we have used the WAS_EndpointInitialState custom property in the activation specification to make a message endpoint start out in a deactivated state. Use the wsadmin tool when we are ready to activate the message endpoint.

The steps in this topic display how to use the AdminControl object and the wsadmin tool to invoke a Message Endpoint MBean to:

For transitioning users: Starting in v7.0, we can use the AdminControl object and the wsadmin tool to deactivate message endpoints to pause the endpoints from receiving messages, and to reactivate message endpoints to resume message handling. If we are connecting to IBM MQ, we can also use the WAS_EndpointInitialState custom property in the IBM MQ messaging provider activation specification to make a message endpoint start out in a deactivated state. Previously, the application server only activated and deactivated message endpoints when the application or resource adapter was started and stopped.trns
