The WebLogic Server uses WebLogic Events to handle internal processes. The
WebLogic Server registers interest in certain topics, like the
WEBLOGIC.ACCOUNTING topic; the evaluator and action for this
registration manages the logging facility in the WebLogic Server.
There are several pages for examination of event handling in the
WebLogic Server. Event Topics gives a summary of topics in the event
server's topic tree, how many registrations of interest there are
in each topic, and how many events have been delivered for those
registrations. You can click on the registration count summary
for any event to see details about the registrations of interest
in that topic.
Event Registrations displays all the registration information
for all of the topics in the event server's topic tree. The
registrations page is divided into four columns: ID, evaluator
summary, action summary, and other details about each registration.
The evaluator and the action are the classes in the
event server that evaluates a received event message; both have a set
of parameters that qualify the scope of the registration's interest in
an event. The WebLogic Server itself submits event messages to the event
server that are evaluated and acted upon.
For more information on WebLogic Events, check the WebLogic Events whitepaper and
the Developers Guide, Using WebLogic
Events, on the WebLogic website.
