Start a mediation
Use this task when you want a mediation to apply its message processing to messages at a selected specialized message point on a destination, at runtime. The mediation to start must be associated with a destination. See Mediating a destination. Start (and stopping) a mediation is a runtime operation. All mediation runtime operations are performed on specialized destination message points called mediation points. When you start a mediation, the mediation begins operating on messages at a selected mediation point. We can start a mediation after the server has started. A mediation cannot operate on new messages at a mediation point after server shutdown begins.
Tip: To ensure that a mediation operates on a specific message at a mediation point, remove all existing messages from the mediation point before you start the mediation. See Delete messages on a mediation point.
To start a mediation, complete the following steps in the administrative console:
