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.
