Applications are built on the concept of message queues, senders, and receivers. Each message is send to a specific queue, and receiving systems consume messages from the queues established to hold their messages. Queues retain all messages sent to them until the messages are consumed by the receiver or expire..
Then, what is a JMS queue?
JMS queue. A staging area that contains messages that have been sent and are waiting to be read (by only one consumer). As the name queue suggests, the messages are delivered in the order sent. A JMS queue guarantees that each message is processed only once.
Secondly, how does a message queue work? A message queue is a queue of messages sent between applications. It includes a sequence of work objects that are waiting to be processed. A message is the data transported between the sender and the receiver application; it's essentially a byte array with some headers at the top.
Secondly, what happens when JMS queue is full?
Throttle back the producer. When the queue fills, nothing can put new messages to it. In WebSphere MQ the producing application then receives a return code indicating that the queue is full. If the application distinguishes between fatal and transient errors, it can stop and retry.
How do you create a queue in JMS?
To create a subscriber queue on WebLogic Server: In the WebLogic Administration Console, select the domain into which you want to create the JMS Module. In the right panel click the New button. On Create JMS System Module, enter a value for the name of the JMS module to be created.
