IBM App Connect Enterprise
WebSphere Message Broker (WMB) is IBM's information broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Business rules can be applied to the data flowing through the message broker to route and transform the information. The product can be considered to be an Enterprise Service Bus providing connectivity between disparate applications.
History
Originally the product was developed by a company named 'NEON', short for 'New Era of Networks'. IBM acquired the product from this company during the late nineties and branded it 'MQSeries Integrator' or 'mqsi' for short. Versions of mqsi ran up to 2.1. The product was added to the Websphere family and rebranded 'Websphere MQ Integrator', still version 2.1. From 2.1 the version numbers are 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. The current major version 6.1 is branded as 'Websphere Message Broker'.
Components
WebSphere Message Broker consists of four components:
- Broker
- Configuration Manager
- User Name Server
- WebSphere Message Brokers Toolkit
How Message Broker works
Overview
The WebSphere Message Broker Toolkit enables developers to graphically design 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[1].
Broker nodes available
A developer can choose from many pre-designed broker nodes. Nodes have different purposes. Some nodes map data from one format to another (for instance, Cobol or PL/I Copybook to canonical XML). Other nodes evaluate content of data and route the flow differently based on certain criteria.
Node types
The following node transformation technology options are available:[2]
- Extended Structured Query Language (ESQL)
- Graphical Message Mapping
- eXtensible Stylesheet Language Transformations (XSLT)
- JavaCompute (as of version 6)
Supported platforms
Operating systems
Currently available platforms for WebSphere Message Brokers 6.1 are:
- AIX
- HP-UX (PA-RISC and IA64)
- Solaris (SPARC and x86-64)
- Linux (x86, x86-64, PPC and 390x)

Trivia
- The Configuration Manager repository was named "BERNARD" after the Configuration Manager development team’s pet gargoyle.[3]
