MuleESB / IBM Integration Bus Interview questions

Could not find what you were looking for? send us the question and we would be happy to answer your question.

What is IBM Integration Bus (IIB)?

You can use IBM Integration Bus to connect applications together, regardless of the message formats or protocols that they support.

What are the main components of IIB/WMB?

The 3 main components in IIB/WMB are Runtime, Development and Administration.

  • Runtime, the broker runtime is the main processing component to which development artifacts are deployed.
  • Development, the Toolkit is used for development of message flows and other development artifacts.
  • Administration Message Broker Explorer is an administration tool used to perform deploys, create brokers or new execution groups, and enable flow monitoring. WMB V8 provides a WebUI tool to view the broker runtime or resources deployed in a browser.
Difference between IIB and Websphere MQ (OR) Difference between queue manager and message broker.

Websphere MQ is a software that uses the AMQ(Asynchronous messaging protocol). You can achieve asynchronous messaging between your applications via Websphere MQ, which will make your infrastructure loosely coupled(Applications can keep working even though other applications are down in the infrastructure).

However with the MQ, we need to create your own program using the Websphere MQ API for message transformations. IIB/WMB allows you to create programs very easily and a lot faster.

MQ is providing you the infrastructure for messaging: queues and topic. IBM Integration Bus (formerly known as WebSphere Message Broker) allows you to apply the common EAI patterns, e.g. Routing, Transformation.

What is EAI pattern?

Enterprise Application Integration (EAI) is the process of connecting disparate systems to allow for "communication" and data sharing between them.
