This topic describes what you should consider when installing
a mediation application.
A mediation application is an enterprise application (EAR file)
that contains a mediation handler enterprise bean project. Installing
the EAR file into WebSphere® Application Server makes
the mediation handler available for use at a destination.
You need to install the EAR file on every server on which you intend
the mediation to run, taking into account the following:
- If you intend the mediation to mediate a topic, you must install
the mediation on every server that has a messaging engine.
- If you add a new member to the bus after you have mediated a topic,
you must install the mediation on the new bus member.
- If you are installing on a queue, you must install the EAR file
on the queue point. In the case of
a partitioned queue, you must install the EAR file on the cluster.
Installing a mediation application on a secure server
If
you are installing a mediation application for use when WebSphere security is enabled, you must
ensure that the messaging engine can access the mediation. For more
information, see Ensuring
the message engine can access mediations.
