Using a WebSphere MQ server to integrate WebSphere MQ queues into a bus

A WebSphere® MQ server represents a WebSphere MQ queue manager or (for WebSphere MQ for z/OS®) queue-sharing group. For interoperation with WebSphere Application Server Version 7.0, the version of WebSphere MQ must be WebSphere MQ for z/OS Version 6 or later, or WebSphere MQ (distributed platforms) Version 7 or later.

Before you begin

WebSphere Application Server can interoperate with WebSphere MQ in any of the following ways:
  • Using WebSphere MQ as an external JMS provider
  • Using a WebSphere MQ link
  • Using a WebSphere MQ server
Each type of interoperation is designed for different situations, and provides different advantages. For information about the differences between these approaches, see Interoperating with a WebSphere MQ network.

Decide which method to use to configure these resources. You can configure WebSphere MQ server resources by using the administrative console as described in this task, or by using the SIBAdminCommands: WebSphere MQ server administrative commands for the AdminTask object.

About this task

To set up and use a WebSphere MQ server, you configure the server properties, add the server to a service integration bus as a bus member, and create a WebSphere MQ queue-type destination. Destinations that are assigned to a WebSphere MQ server bus member can also be mediated.

You add the WebSphere MQ server as a bus member so that messaging engines on the bus can access queues on the target WebSphere MQ system. If your WebSphere MQ server is connected to a queue-sharing group, your bus applications can access shared queues on the target installation.

Notes:
  • You can configure a WebSphere MQ server to connect to a WebSphere MQ queue manager by using either a bindings mode or a client mode connection. To use client mode with WebSphere MQ for z/OS, you need an additional product called the Client Attach Facility.
  • You should configure the queues on the WebSphere MQ network as "shareable". This allows multiple server instances to get messages from the queues.
Maintenance note: A WebSphere® MQ server uses code provided by the WebSphere MQ resource adapter, which is automatically installed as part of the product. However, when you migrate WebSphere Application Server profiles from maintenance level 7.0.0.0 to later maintenance levels, or from later maintenance levels to the 7.0.0.0 maintenance level, you must manually adjust the WebSphere MQ resource adapter configuration. For more information, see Adjusting the WebSphere MQ resource adapter configuration when migrating profiles between maintenance level 7.0.0.0 and later levels.

Procedure

  1. Create a WebSphere MQ server definition and configure the server properties.
  2. Add the new WebSphere MQ server as a member of a bus so that messaging engines on the bus can access queues on the target WebSphere MQ installation.
  3. Create a WebSphere MQ queue type destination for the new bus member and assign it to a WebSphere MQ queue.
  4. Optional: Mediate the new destination by using the WebSphere MQ queue as the mediation point.
