Configuring a new mediation

Use this task to configure a mediation in the administrative console.

Before you begin

This task assumes that you have installed a mediation application on the server where you want to run the mediation. For more information, see Installing a mediation.

About this task

Configuring a new mediation makes it available for use in mediating one or more destinations.

In this task, you use the administrative console to configure a mediation:

Procedure

  1. Click Service integration -> Buses -> bus_name -> [Destination resources] Mediations.
  2. In the content pane, click New.
  3. Specify the following properties for the mediation:
    Mediation name
    Type a name for the mediation that is unique to the service integration bus. This name is used to identify the mediation for administrative purposes.
    Description
    Optionally, type a description for the mediation.
    Handler list name
    Type the handler list name. This is the name that was used when the mediation handler was deployed. Handler list names are unique within the WebSphere® Application Server administrative cell.
    Global transaction
    Optionally, select this option (setting it to true) if you want to start a global transaction for each message mediated by the mediation. By default, Global transaction is set to false, and a global transaction is not started when a message is mediated.
    Allow concurrent mediation
    Optionally, select this option (setting it to true) if you want to mediate multiple messages at the mediated destination.
    By default, Allow concurrent mediation is set to false, and concurrent mediations are not allowed.
    Note: Do not allow concurrent mediation if message ordering is important.
    Selector
    Optionally, type a message selector to control which messages are mediated by the mediation. The selector operates on the content of the message header. The syntax of the message selector is defined by the JMS specification.

    If the message content meets the conditions of the selector, the message is mediated. Otherwise, the message is not mediated.

    Discriminator
    Optionally, type a message discriminator to control which messages are mediated by the mediation. Message discriminators conform to the publish/subscribe topicspace syntax.

    If the message meets the conditions of the discriminator, the message is mediated. Otherwise, the message is not mediated.

  4. Click OK.
  5. Save your changes to the master configuration.

Results

You have configured a new mediation.

What to do next

You can use the mediation to mediate a destination. For more information, see Mediating a destination.
