Create a new WebSphere MQ link

A WebSphere MQ link provides a server to server channel connection between a service integration bus and a WebSphere MQ queue manager or queue-sharing group, which acts as the gateway to the WebSphere MQ network. Use the foreign bus connection wizard to create a foreign bus and link it to the WebSphere MQ network through a WebSphere MQ link.

Decide which method to use to configure these resources. We can create a new WebSphere MQ link using the console as described in this task, or we can create a new WebSphere MQ link by . The following resources must be defined in WebSphere Application Server:

The following resources must be defined in WebSphere MQ:

Use foreign bus connection wizard to connect a bus and a WebSphere MQ network. We can configure the connection for either point-to-point or publish-subscribe messaging.

Specifically, the wizard helps you configure the following resources:

The wizard does not ask you to set all possible properties of a WebSphere MQ link, and many of the properties are set to default values. We can fine tune these properties afterward if necessary, by modifying the WebSphere MQ link.

For a sample configuration showing a systems view of the setup for a WebSphere MQ link, see WebSphere MQ link sample configuration.

  1. Use the foreign bus connection wizard to connect a bus and a WebSphere MQ network to use point-to-point messaging or publish-subscribe messaging.

    A WebSphere MQ link is created and configured as part of the action of the wizard.

    We can subsequently convert a point-to-point connection to a publish/subscribe connection, by adding a publish/subscribe broker on the WebSphere MQ link for the connection.

  2. Optional: Modify the new WebSphere MQ link.

    When creating a new WebSphere MQ link, the following properties are set to default values:

    We can fine tune these properties by modifying the link.

  3. Optional: Add or modify the WebSphere MQ receiver channel.

    If we did not choose to Enable Service integration bus to WebSphere MQ message flow in the foreign bus connection wizard, we have not yet defined a WebSphere MQ receiver channel. If we did choose this option in the wizard, we have defined the receiver channel name, host name and communication port, and the wizard has used default values for the following properties:

    • Inbound nonpersistent message reliability

    • Inbound persistent message reliability

    • Prefer queue points local to this link's messaging engine

    • Initial state

    We can fine tune these properties by modifying the channel.

  4. Optional: Add or modify the WebSphere MQ sender channel

    If we did not choose to Enable WebSphere MQ to Service integration bus message flow in the foreign bus connection wizard, we have not yet defined a WebSphere MQ sender channel. If we did choose this option in the wizard, we have defined the sender channel name, host name, communication port and transport chain, and the wizard has used default values for the following properties:

    • Disconnect interval

    • Short retry count

    • Short retry interval

    • Long retry count

    • Long retry interval

    • Initial state

    We can fine tune these properties by modifying the channel.
