vice component subscriptions are created during design time and cannot be
modified from the
Business Events
dashboard.
If an SOA composite application includes a business event
subscription and different revisions of the composite are de-
ployed, event subscriptions from all revisions of the compos-
ite are active and receive messages. To receive an event with
the latest revision of the composite only, it is recommended
that previous revisions of the composite be retired or unde-
ployed.
Business events that have faulted and been identified as recoverable can be
retried or aborted by clicking on the
Faults
tab in the
Business Events
dash-
board. The faults page enlists errors occurring in business events including the
error message, if a recovery can be attempted for the fault, fault occurrence
timestamp, event namespace, event name, subscriber, and the subscription
type (database or service component). Recoverable faults for which recovery
actions can be performed are made available by selecting the
Show only re-
coverable faults
checkbox and performing the
Retry
operation.
Even though the EDN framework is designed to pretty much be a black box, it
provides the ability to view event payloads. You can do this in two ways. If the
mode is set to
EDN-JMS
, pause consumption from the
EDNQueue
queue to be
able to see what payload is being sent to the event engine. Follow these steps
to do this:
1.
Log in to the Oracle WebLogic Server Administration Console.
2.
Click on
JMS Modules
under the
Messaging
panel.
3.
Click on
SOAJMSModule
.
4.
Click on
EDNQueue
.
5.
Click on the
Control
tab.
