All you need to know about some amazing features of IBM WebSphere MQ

IBM WebSphere MQ is one of the amazing network software product that enables applications to communicate under many diverse computing environment. It provides smarter and faster connection to send and receive data between applications over network. It has some unique applications that makes it one of the leading middleware for messaging and queuing. To have an overall idea about this amazing product and its key functionalities, please read our previous blog: Know About Amazing IBM WebSphere MQ. Here we discuss in detail about using IBM WebSphere MQ, its amazing features and its contribution to service oriented architecture.

Using IBM WebSphere MQ

• Develop and administer IBM WebSphere MQ with the IBM WebSphere MQ Explorer GUI or by executing commands from a command window or application. 
• Program applications to send and receive messages by calling one of the programming interfaces. Programming interfaces are provided for various languages, and include the standard JMS programming interface, and classes for the Windows communication baseline. Send and receive IBM WebSphere MQ messages from browsers with the HTTP protocol.

Features of IBM WebSphere MQ

Some of the amazing features of IBM WebSpehere MQ are as follows:

i) MQ gives application designers with a procedure to achieve non-time-dependent architecture. Messages can be sent from one application to another, regardless of whether the applications are running at the same time. If a message receiver application is not working when a sender sends it a message, the queue manager will hold the message until the receiver asks for it. Ordering of all messages is retained, by default this is in FIFO order of receipt at the local queue within precedence of the message. 

ii) It gives a way for transmitting data between different architectures and protocols, such as Big Endian to Little Endian, or EBCDIC to ASCII. This is proficient through the use of message data exits. Exits are compiled applications that run on the queue manager host, and are accomplished by the IBM MQ software at the time data transmission is required. MQ requires to be memorialize that a message in the context of MQ has no ramification other than a collecting of data.

iii) MQ is derived and can be used as a boomed substitute for many forms of intercommunication. MQ channels integrates one queue manager to another over a network. We can develop MQ channels yourself, or a queue manager in a cluster of queue managers develops MQ channels when they are needed.

iv) A system can operates on the same computer as the queue manager, or on a different one. If it operates on the same system, it is a IBM WebSphere MQ server application. If it operates on a different computer, it is a IBM WebSphere MQ client application. Whether it is IBM WebSphere MQ client or server makes no difference to the application. You can develop a client/server application with IBM WebSphere MQ clients or servers.

v) IBM MQ gives guarantee one-time delivery of messages across various platforms. The product prioritises accuracy and clout of message traffic, and provides that a message should never be lost if MQ is appropriately configured.

vi) It artifice the Java Message Service (JMS) standard API, and also has its own bailiwick API, known as the Message Queuing Interface (MQI), which anticipate the JMS several years in continuation. As of version 8.0.0.4, MQ also supports the MQ Light API. Unlike email, MQ itself is authoritive for determining the destination of messages by the definition of queues, so processing of sent messages can be moved to a different application at a different targets. MQ provides a boom routing architecture, permitting messages to be routed via different paths around a network of MQ managers. MQ can be achieve as a cluster, where different MQ operation share the processing of messages to allow greater performance and load balancing.

vii) When your application requires to transmit data to different application, it puts the data into a message. It puts the message onto a queue, or subscribes the message to a topic. Applications communicate with each other by exchanging messages on queues. The main use of IBM WebSphere MQ is to send or exchange messages. One system puts a message on a queue on one computer, and different systems gets the equal message from another queue on a different computer. The queue managers on the different computers work collaborate to transfer the message from the first queue to the second queue. The applications do not connect with each other, the queue managers do. We can have multiple queue manager on one computer. We can have multiple queues and topics on one queue manager.

A Cornerstone in Service Oriented Architecture

IBM MQ is a cornerstone in IBM's Service Oriented Architecture (SOA) strategy, subject to the universal messaging backbone across 80 different platform. The growing importance of SOA and the growth of Web Services and other connectivity mechanisms are clearly important developments. Because of the roughly coupled nature of the message queuing model, a large number of existing MQ customers feel that they are already adopting SOA principles. The MQ Service definition support pack MA93 permits MQ applications to be catalogued as software assets that can be reused and composed as Web Services.

IBM WebSphere MQ that enables applications to communicate at diverse computing environment

In the year 1993, on the December IBM launched for the first time a group of network software products known as IBM MQ. It was primitively known as MQ Series and later in the year 2002 it was renamed as the WebSphere MQ, when it joined the suite of WebSphere products. Down the line in the year 2014 on April it was again renamed as IBM MQ. There are various products that are included in the MQ group and those are IBM MQ, IBM MQ Advanced, IBM MQ Appliance and IBM MQ for z/OS. We can use IBM WebSphere MQ to readily use applications to communicate at different times and in many diverse computing environments:

• IBM MQ, is IBM's Messaging solution for Enterprise and IBM's Message Oriented Middleware atonement. IBM WebSphere MQ is messaging for applications. It sends messages to networks of diverse components. Your application joins to IBM WebSphere MQ  to send or receive a message . 
• IBM WebSphere MQ knobs the different processors, operating systems, subsystems, and communication protocols it rendezvous in transferring the message. If a processor is temporarily unavailable,  IBM WebSphere MQ queues the message and forwards it when the connection is back online. 
• It is a middleware for messaging and queuing, with point-to-point, publish/subscribe and file transmission way of operation. Applications can promulgate messages to many endorser over multicast. An application has a choice of programming interfaces, and programming languages to connect to IBM WebSphere MQ.

Some of the key points on WebSphere MQ

Messaging: Programs connects by sending each other data in messages rather than by calling each other precisely.

Queuing: Messages are placed on queues, so that programs can run freely of each other, at distinct speeds and times, in different locations, and without having a direct communication between them.

Point-to-point: Applications send messages to a queue, or to a list of queues. The sender must identify the name of the destination, but not where it is.

Publish or subscribe: Applications publish a message on a topic, such as the output of a game played by a team. IBM WebSphere MQ sends simulation of the message to applications that subscribe to the results topic. They receive the message with the output of games played by the team. The publisher does not know the names of subscribers, or where they are.

Multicast: Multicast is an productive form of publish/subscribe messaging that scales to many subscribers. It transmits the effort of sending a copy of a publication to each subscriber from IBM WebSphere MQ to the network. Once a way for the publication is built between the publisher and subscriber, IBM WebSphere MQ is not engaged in forwarding the publication.

File Transfer: Files are transmitted in messages. IBM WebSphere MQ File Transfer Edition administers the transfer of files and the administration to set up automated transfers and log the results. You can sum up the file transfer with other file transfer systems,  with IBM WebSphere MQ messaging, and the web.

Telemetry: IBM WebSphere MQ Telemetry is messaging for devices. IBM WebSphere MQ integrates device and application messaging all together. It joins the internet, applications, services, and decision makers with networks of instrumented devices. IBM WebSphere MQ Telemetry has an capable messaging protocol that integrates a large numbers of devices over a network. The messaging protocol is published, so that it can be assimilated into devices. You can also develop device programs with one of the published programming interfaces for the protocol.

How does it help?

IBM WebSphere MQ sends and receives data between your applications, and over networks. Message delivery is confirmed and decoupled from the application. Assured, because IBM WebSphere MQ exchanges messages transferable and decoupled, because applications do not have to check that messages they sent are conveyed safely. You can secure message delivery between queue managers with SSL/TLS. With Advanced Message Security (AMS), you can secure and sign messages between being put by one application and bring back by another. Application programmers do not need to have communications programming knowledge. Conclusive connections are generally faster and smarter, but client connections allow for a more robust, easily changeable application design. For instance, with a client connection, the physical location of the queue manager is irrelevant, as long as it is reachable over the network.
