Use WebSphere® Integration
Developer to create a module containing a Policy Resolution mediation
primitive.
About this task
You can control service requests dynamically, by using policies
that allow you to override module properties at run time. Such policies
are sometimes referred to as
mediation policies and are
stored in WebSphere Service
Registry and Repository (WSRR). You can define one or more policies
for your module, and each policy can override one or more module properties.
Optionally, you can create one or more gate conditions on each policy
attachment. At run time, gate conditions are compared to the condition
values in the message; all of the gate conditions must be met before
an associated policy can be used. Whether property values are overridden
for a particular service interaction depends on the message being
processed and the
Mediation policy processing model defined
in the information center.
