WebSphere MQ bindings

The WebSphere MQ binding provides Service Component Architecture connectivity with WebSphere MQ applications.

Use the WebSphere MQ export and import bindings to integrate directly with a WebSphere MQ-based system from your server environment. This eliminates the need to use MQ Link or Client Link features of the Service Integration Bus.

When a component interacts with a WebSphere MQ service by way of an import, the WebSphere MQ import binding uses a queue to which data will be sent and a queue where the reply can be received.

When an SCA module provides a service to WebSphere MQ clients, the WebSphere MQ export binding uses a queue where the request can be received and the response can be sent. The function selector provides a mapping to the operation on the target component to be invoked.

Conversion of the payload data to and from an MQ message is done through the MQ body data handler or data binding. Conversion of the header data to and from an MQ message is done through the MQ header data binding.

For information about the WebSphere MQ versions supported, see the detailed system requirements web page.

• WebSphere MQ bindings overview
  

  The WebSphere MQ binding provides integration with native MQ-based applications.

• Key features of a WebSphere MQ binding
  Key features of a WebSphere MQ binding include headers, Java EE artifacts, and created Java EE resources.
• WebSphere MQ headers
  WebSphere MQ headers incorporate certain conventions for conversion to the service component architecture (SCA) messages.
• Adding MQCIH statically in a WebSphere MQ binding
  IBM BPM supports adding MQCIH header information statically without using a mediation module.
• External clients
  IBM BPM can send messages to, or receive messages from, external clients using WebSphere MQ bindings.
• Troubleshooting WebSphere MQ bindings
  

  You can diagnose and fix faults and failure conditions that occur with WebSphere MQ bindings.

• Handling exceptions
  The way in which the binding is configured determines how exceptions that are raised by data handlers or data bindings are handled. Additionally, the nature of the mediation flow dictates the behavior of the system when such an exception is thrown.
