  • Universal Messaging with IBM MQ V8 IBM Redbooks Solution Guide
    ® Universal Messaging with IBM MQ V8 IBM Redbooks Solution Guide By implementing messaging technologies, businesses can use a consistent approach to connectivity, decoupling the business application from the complex tasks of handling failures, error recovery, transaction integrity, security, and scalability. IBM® MQ® provides the universal messaging backbone for service-oriented architecture (SOA) connectivity (Figure 1). It connects virtually any commercial IT system, with support for more than 80 platforms. Figure 1. Overview of the IBM MQ solution IBM MQ includes a choice of APIs and supports the Java™ Message Service (JMS) API. IBM MQ is the market-leading messaging integration middleware product. Originally introduced in 1993 (under the IBM MQSeries® name), IBM MQ provides an available, reliable, scalable, secure, and high-performance transport mechanism to address businesses connectivity requirements. Universal Messaging with IBM MQ V8 1 Did you know? IBM MQ has the following credentials and industry recognition: It is the most widely deployed messaging backbone, with over 10,000 customers using the IBM messaging backbone: o Over 90% of Fortune 50 companies and of Fortune 10 companies use the IBM messaging backbone. o Over 80% of Global 25 companies and 70% of Global 10 companies use the IBM messaging backbone. It is entrusted with tens of billions of messages each day: o A government client sends 675 million messages per day. o A banking client handles over 213 million messages per day on IBM z/OS® alone. It is relied upon as the mission-critical backbone: o A financial markets client handles USD 1 trillion worth of traffic per day on one IBM MQ network.

  • 17059: Are Z/OS & Distributed MQ Platforms Like Oil and Water?
    17059: Are z/OS & distributed MQ platforms like oil and water? Mark Taylor Lyn Elkins [email protected] [email protected] IBM Hursley IBM ATS Insert Custom Session QR if Desired. Introduction • One objective of MQ is isolating apps from needing to understand platforms ‒ There is a common API that can be expressed in many languages • Another objective is to have (reasonably) common operational model ‒ Much of admin is the same on all platforms • But it’s not all the same ‒ One dichotomy has always been whether to be natural to MQ-ness or behave like other things on the platform ‒ Some features don’t make sense on some platforms For example, .Net interface is only on Windows ‒ Some features have not been implemented everywhere for other reasons • So there are differences, and that is what this presentation will cover • Will base this on V8 Code Streams • There are essentially two implementations of MQ from Hursley lab ‒ z/OS ‒ Distributed (Windows, Unix, Linux, i) ‒ There are some further subspecies variants like VSE or NSS • Within Distributed implementation, there are some platform unique features ‒ But we won’t discuss those here ‒ Most platform-unique code abstracts OS facilities like locking or NLS or threads • In the early days, some code was written for one and then “ported” ‒ In particular, the channel code ‒ Meant double-fixing, and re-porting for each release • Internal architecture (eg tasks, threads) very different ‒ But we won't discuss much of that. Understanding externals is more important • Since V7.0, some code is
