Modifying the properties of a mediation

Use this task to set properties to control some aspects of the runtime behavior of an existing mediation.

Before you begin

You should ensure that the mediation exists. If you want to configure a new mediation, see Configuring a new mediation.

About this task

Using the administrative console, you can specify the following options for a selected mediation:

Procedure

  1. Click Service integration -> Buses -> bus_name -> [Destination resources] Mediations -> mediation_name .
  2. Select any of the following properties for the mediation:
    Description
    Optionally, type a description of the behavior of the mediation, taking into account any properties specified for the mediation.
    Handler list name
    Type the name of the handler list that was defined when the mediation was deployed. Handler list names start with an uppercase letter, and are unique within the service integration bus.
    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 meets the conditions of the selector, the message is mediated. Otherwise, the message is not mediated.

    For information about the properties that can be used in selectors, see Message properties support for mediations.

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

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

  3. Specify any additional properties.
  4. Click OK.
  5. Save your changes to the master configuration.

Results

You have changed the properties for the selected mediation.
