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:
- Each message processed by the mediation runs within a global transaction.
- The mediation processes messages concurrently.
- The mediation processes only those messages that meet some selection criteria.
Procedure
- Click .
- 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.
- Optional: Specify any additional properties.
- Click OK.
- Save your changes to the master configuration.

You have changed the properties for the selected mediation.
