About Management Rules

Managementrules enable you to automate routine administration tasks, congure self-tuning
ofthe application server for diverse runtime condition and improve availability by preventing
failures.A management rule contains an action to be taken when a specied event occurs or a
setthreshold is reached. You can set management rules that can automatically take corrective
action,based on events that you specify.
Amanagement rule consists of two parts — event and action:
■Anevent uses the JMX notication mechanism to trigger a predened action.
■Anaction is triggered when an associated event occurs. An action is an MBean which is a
noticationlistener which implements javax.management.NotificationListener.
Forexample, an event could be a SEVERE message logged by the EJB logger, and an action
couldbe alerting an administrator with the log message contents. When the event happens,
eventdata is passed as part of userData part of the javax.management.Notification.
Theaction specied in your rule has to be implemented as a custom MBean. Therefore, before
conguringa management rule, you should deploy a custom MBean designed to receive event
