IBM 2016#MOM IntroductionMOM Message-oriented middlewareIBM MQ, IBM MessageSight (MQTT), Tuxedo, TIBCO, HiveMQ (MQTT), RabbitMQ (MQTT/AMQP), ActiveMQ (AMQP), Microsoft MSMQ - BrokersAsynchronous communication Message Sender does not need to wait for response from Message Receiver (fire-and-forget / non-blocking)Loose coupling message producer does not need to know the details of message consumer, they do not need to be active at the same timePoint-to-point (queue), Publish-subscribe (topic)

IBM 2016#MOM IntroductionMOM Message-oriented middlewareTransactions atomicity, consistency, isolation, durability, scalability, security, acknowledgment, routing, transformation, filtering, priority, data enrichment, data aggregation (async request, delayed response), persistence (QoS)Message Binary or Character dataQueue Managed object that implements the point-to-point messaging model and can receive and store messages in a MOMTopic Managed object that implements the publish-subscribe messaging model and receive and store messages in a MOM

IBM 2016#MOM Message Oriented Middleware

IBM 2016#MOM Message Oriented MiddlewarePoint-to-Point (Queue)One to one (11), many to one (*1)One queue per receiver, one message received by one receiver

IBM 2016#MOM Message Oriented MiddlewarePublish-Subscribe (Topic)One to Many (1*), Many to Many (**)Topic, same message may be received by many receivers

IBM 2016#MOM Message Oriented MiddlewarePoint-to-Point (FIFO Queue)All messages have the same priorityMessages are delivered in the order they enter the queue - FIFO

IBM 2016#MOM Message Oriented MiddlewarePoint-to-Point (Priority Messages / Queue)Queue buffers the messages and orders them according to their priority when they enter the queue (priority applied at point T in time)Messages are delivered in the order they enter the queue - FIFO

IBM 2016#IBM MQ MQ ObjectsIBM Message Queue Objects Queue Manager (QMGR)Queue Manager - Manager, orchestrator for a given message queue scheme. The QM coordinates the MQ objects, sends messages to other queue managers over a message channel. The queue manager may be co-located with an application or located in a separate server host.

IBM 2016#MOM Message Oriented MiddlewareIBM Message Queue Objects Queue TypesApplication: Local, Remote, Alias, Model, DynamicMQ internal: Dead-letter, Initiation, Transmission, Cluster, Comand, Event, Reply-to

IBM 2016#IBM MQ MQ ObjectsIBM Message Queue ObjectsProcess Definition - Defines a feature that can start an application in response to a trigger event. Attributes include application type, application ID (path) and data (MIME type) to the applicationChannels - Logical communication link provides communication path from one MQM to another or from external client to MQM. It shields applications from underlying protocols.Listeners They listen and accept remote connections and start inbound channels.
