Checking the message delivery status and the action to be taken for accumulated messages (Procedure for pausing CJMSP Broker)

This subsection describes the procedure for checking the message delivery status of Cosminexus JMS Provider and the procedure of action when the messages accumulate.

With this method, an exception might occur due to the occurrence of application timeout after CJMSP Broker is paused.

To delete the messages safely, see Appendix E.10 Checking the message delivery status and the action to be taken for accumulated messages (Procedure for stopping an application).

The following figure shows the procedure for checking the message delivery status and the action to be taken for accumulated messages (procedure for pausing CJMSP Broker).
