Overview

The WebSphere Message Broker runtime reduces cost and complexity of IT systems by unifying the method a company uses to implement interfaces between disparate systems. WMB runtime forms the Enterprise Service Bus of a Service Oriented Architecture by efficiently increasing the flexibility of connecting unlike systems into a unified, homogeneous architecture. The key feature of the WMB product is the ability to abstract the business logic away from transport or protocol specifics.

The WebSphere Message Broker Toolkit enables developers to graphically design mediations, known as message flows, and related artifacts. Once developed, these resources can be packaged into a broker archive (BAR) file and deployed into the runtime environment. At this point, the broker is able to continually process messages according to the logic described by the message flow.[7] A wide variety of data formats are supported, and may be modeled using standard XML Schema and DFDL schema. After modeling, a developer can create transformations between various formats using nodes supplied in the Toolkit, such as Mapping node, Compute nodes, or database nodes.

WebSphere Message Broker flows can be used in a Service Oriented Architecture, and if properly designed by Middleware Analysts, integrated into event-driven SOA schemas, sometimes referred to as SOA 2.0. Businesses rely on the processing of events, which might be part of a business process, such as issuing a trade order, purchasing an insurance policy, reading data using a sensor, or monitoring information gathered about IT infrastructure performance. WebSphere Message Broker includes rich complex-event-processing capabilities that enable analysis of events to perform validation, enrichment, transformation and intelligent routing of messages based on a set of business rules.

A developer creates WMB functionality in a cyclical workflow, probably more agile than most other software development. Developers will create a message flow, generate a BAR file, deploy the message flow contained in the BAR file, test the message flow and repeat as necessary to achieve reliable functionality.

MQSI Commands are runtime commands to interact with Message Broker Toolkit.

Introduction

               IBM WebSphere Message Broker

     WebSphere Message Broker (WMB) is IBM's integration broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through the message broker to route and transform the information. 

The product is an Enterprise Service Bus providing connectivity between applications and services in a Service Oriented Architecture.

The key feature of the WMB product is the ability to abstract the business logic away from transport or protocol specifics.

HISTORY :

Originally the product was developed by NEON (New Era of Networks) Inc., a company which was acquired by Sybase in 2001. The product was later re-branded as an IBM product called 'MQSeries Integrator' (or 'MQSI' for short). Versions of MQSI ran up to 2.0.

The product was added to the WebSphere family and rebranded 'WebSphere MQ Integrator', at version 2.1. After 2.1 the version numbers became more synchronized with the rest of the WebSphere family and jumped to version 5.0. The name changed to 'WebSphere Business Integration Message Broker' (WBIMB). In this version the development environment was redesigned using Eclipse and support for Web services was integrated into the product. Since version 6.0 the product has been known as 'WebSphere Message Broker'. WebSphere Message Broker version 7.0 was announced in October 2009,[2] and WebSphere Message Broker version 8.0 announced in October 2011[3]

In April 2013, IBM announced that the WebSphere Message Broker product was undergoing another rebranding name change.[4] The WMB product version for the new product name of IBM Integration Bus is version 9 and includes new nodes such as the Decision Service node which enables content based routing based on a rules engine and requires IBM WebSphere Operational Decision Management product.[5] The IBM WebSphere Enterprise Service Bus product has been discontinued with the release of IBM Integration Bus and IBM is offering transitional licenses to move to IBM Integration Bus.[6] The WebSphere Message Broker Transfer License for WebSphere Enterprise Service Bus enables customers to exchange some or all of their WebSphere Enterprise Service Bus license entitlements for WebSphere Message Broker license entitlements. Following the license transfer, entitlement to use WebSphere Enterprise Service Bus will be reduced or cease. This reflects the WebSphere Enterprise Service Bus license entitlements being relinquished during the exchange. IBM announced at Impact 2013 that WESB will be end-of-life in five years and no further feature development of the WESB product will occur.

-IBM Integration Bus (WMB V9) provides capabilities to build solutions needed to support diverse integration requirements through a set of connectors to a range of data sources, including packaged applications, files, mobile devices, messaging systems, and databases. A benefit of using IBM Integration Bus is that the tool enables existing applications for Web Services without costly legacy application rewrites. IIB avoids the point-to-point strain on development resources by connecting any application or service over multiple protocols, including SOAP, HTTP and JMS.[1] Modern secure authentication mechanisms, including the ability to perform actions on behalf of masquerading or delegate users, through MQ, HTTP and SOAP nodes are supported such as LDAP, X-AUTH, O-AUTH, and two-way SSL.also,a new Global Cache feature enhances overall performance capability and throughput rates
