`
`MQSeries family
`
`Chapter 1. MQSeries and business integration
`
`The last few years have seen a growing interest and investment in messaging
`middleware. IBM’s MQSeries is an industry leader in this area, and provides a
`messaging infrastructure to many diverse businesses and applications.
`
`IBM has developed a family of products, based around the messaging transport
`layer, that provides not only the fundamental requirements of secure, reliable
`information exchange, but also incorporates services and business process support
`to help you to make best use of your investment in systems and applications. The
`richness and flexibility of this support enables you to respond to new opportunities
`that arise when your business grows and diversifies.
`
`The MQSeries family
`The MQSeries family consists of three complementary offerings:
` (cid:1) “MQSeries”
` (cid:1) “MQSeries Integrator”
`(cid:1) “MQSeries Workflow” on page 4
`
` MQSeries
`
`MQSeries provides assured, once-only delivery of messages between your IT
`systems. It connects more than thirty industry platforms including those from IBM,
`Microsoft, and Sun, using a variety of communications protocols.
`
`MQSeries provides rich support for applications:
`(cid:1) Application programming interfaces: the Message Queue Interface (MQI) and
`Application Messaging Interface (AMI) are supported in several programming
`languages.
`(cid:1) Communication models: point-to-point (including request/reply and client/server)
`and publish/subscribe are supported.
`(cid:1) The complexities of communications programming are handled by the
`messaging services and are therefore removed from the application logic.
`(cid:1) Applications can access other systems and interfaces through gateways and
`adapters to products such as Lotus Domino, Microsoft Exchange/Outlook,
`SAP/R3, and IBM’s CICS and IMS/ESA products.
`
` MQSeries Integrator
`MQSeries Integrator works with MQSeries messaging, extending its basic
`connectivity and transport capabilities to provide a powerful message broker
`solution driven by business rules. Messages are formed, routed, and transformed
`according to the rules defined by an easy-to-use graphical user interface.
`
`Diverse applications can exchange information in unlike forms, with brokers
`handling the processing required for the information to arrive in the right place in
`the correct format, according to the rules you have defined. The applications have
`no need to know anything other than their own conventions and requirements.

`
`

`
`
`
`
`
`Business integration
`
`Applications also have much greater flexibility in selecting which messages they
`wish to receive, because they can specify a topic filter, or a content-based filter, or
`both, to control the messages made available to them.
`
`MQSeries Integrator provides a framework that supports supplied, basic, functions
`along with plug-in enhancements, to enable rapid construction and modification of
`business processing rules that are applied to messages in the system.
`
` MQSeries Workflow
`MQSeries Workflow works with MQSeries messaging to add a further dimension to
`your business integration by aligning and integrating an organization’s staff
`resources, processes, and capabilities with business strategies. It enables
`organizations to accelerate process flow, optimize costs, eliminate errors and
`improve workgroup productivity.
`
`MQSeries Workflow is designed to enable integration of all participants in the
`business process, including those external to your organization. It ensures the right
`information gets to the right person at the right time.
`
`MQSeries Workflow can be used in combination with MQSeries Integrator,
`providing a high level of flexibility to allow business and message processing to be
`as simple or as complicated as your business demands.
`
`Using MQSeries for business integration
`MQSeries is the focal point of the IBM Business Integration strategy, which
`addresses integration of applications, data, and processes from both business and
`IT perspectives.
`
`Business integration is the coordination and cooperation of all your business
`processes and applications. It involves bringing together the data and process
`intelligence in your enterprise, and harnessing these to enable all your applications
`and your users to achieve their business needs.
`
`Business integration means that:
`(cid:1) You can connect customers, suppliers, partners, and service providers, with
`continuing security and control, to enable newly built and re-engineered
`applications for more effective business processes (for example, Supply Chain
`Management).
`(cid:1) You can make mergers and acquisitions a success by integrating dissimilar IT
`infrastructures from two or more companies so they can work as a single entity.
`(cid:1) You can react more quickly to market trends and opportunities because your IT
`systems are flexible and dependable, and no longer constraining.
`(cid:1) The barriers of diverse computer systems, geographic boundaries, time
`differences, language and format differences, and different methods of working
`can all be overcome.
`
`You can use the MQSeries family products to support your business integration
`needs:
`(cid:1) MQSeries messaging provides a secure and far-reaching communications
`infrastructure.

`
`
`
`
`Using MQSeries Integrator
`
`(cid:1) MQSeries Integrator and MQSeries Workflow provide a range of services that
`allow you to apply intelligence to your business data as it travels through your
`network.
`
`Using MQSeries Integrator in your business
`MQSeries Integrator addresses the needs of business and application integration
`through management of information flow. It provides services based on message
`brokers to allow you to:
`(cid:1) Route a message to several destinations, using rules that act on the contents
`of one or more of the fields in the message or message header.
`(cid:1) Transform a message, so that applications using different formats can
`exchange messages in their own formats.
`(cid:1) Store and retrieve a message, or part of a message, in a database.
`(cid:1) Modify the contents of a message (for example, by adding data extracted from
`a database).
`(cid:1) Publish a message to make it available to other applications. Other
`applications can choose to receive publications that relate to specific topics, or
`that have specific content, or both.
`(cid:1) Create structured topic names, topic-based access control functions,
`content-based subscriptions, and subscription points.
`(cid:1) Exploit a plug-in interface to develop message processing node types that can
`be incorporated into the broker framework to complement or replace the
`supplied nodes, or to incorporate node types developed by Independent
`Software Vendors (ISVs).
`(cid:1) Enable instrumentation by products such as those developed by Tivoli, using
`system management hooks.
`
`The benefits of MQSeries Integrator can be realized both within and beyond your
`enterprise:
`(cid:1) Your processes and applications can be integrated by providing message and
`data transformations in a single place, the broker. This helps reduce costs of
`application upgrades and modifications.
`(cid:1) You can extend your systems to reach your suppliers and customers, by
`meeting their interface requirements within your brokers. This can help you
`improve the quality of your interactions and allow you to respond more quickly
`to changing or additional requirements.
`
`For a practical illustration of the use of MQSeries Integrator in business, see
`Chapter 3, “MQSeries Integrator: a business scenario” on page 29.
`
`MQSeries Integrator Version 2.0 and previous IBM offerings
`The following offerings from IBM are enhanced and extended by MQSeries
`Integrator Version 2.0:

`
`

`
`
`
`
`
`Getting started
`
`MQSeries Integrator Version 2.0 extends the capabilities of MQSeries Integrator
`Version 1 and MQSeries Publish/Subscribe by supporting:
`(cid:1) Integration of the publish/subscribe and rules and transformation functions,
`enabling the output from the rules engine to be directed straight to the
`publish/subscribe service without use of an intermediate queue.
`(cid:1) Enhanced publish/subscribe function through exploitation of structured topic
`names, access control, content-based subscriptions, and subscription points.
`(cid:1) Enhancement of message processing through the addition of new message
`processing nodes to complement or replace the supplied nodes.
`(cid:1) Interfaces that allow messages to be enriched with information from a
`database, or to be stored in a database.
`
`You can upgrade your applications, messages, and brokers to take advantage of
`the enhancements in Version 2.0. You can also continue to use your existing
`applications
