Use the failed event manager to find and manage failed events on
all servers in a cell. The interface enables you to view (and in some cases,
edit) the data for a failed event, resubmit a failed event, or delete a failed
event.
The failed event manager handles the following types of events:
- Service Component Architecture (SCA) failed events. In the context of
SCA, an event is a request or response that is received by a service application.
It can come from an external source (such as an inbound application adapter)
or an external invocation to a Web service. The event is comprised of a reference
to the business logic it wants to operate and its data, stored in a Service
Data Object (a business object). When an event is received, it is processed
by the appropriate application business logic.
- Java Message Service (JMS) failed events. In the context of JMS, a failed
event is generated when a JMS data binding or function selector operation
fails, or when an exception occurs in a downstream component and is thrown
back to the JMS export or import. The Recovery service handles failed events
from JMS data bindings and MQ JMS data bindings.
- Business Process Choreographer stopped, terminated,
and failed events. In the context of Business Process Choreographer, exceptions
can occur that, if not handled by the process logic, cause an activity to
stop or the process instance to fail. A failed event is generated when a long-running
Business Process Execution Language (BPEL) process fails and one of the following
happens:
- The process instance enters the Failed or Terminated state
- An activity enters the Stopped state
- Business Flow Manager hold queue events. You can use
the failed event manager to manage navigation messages that are stored in
the Business Flow Manager hold queue. A navigation message might be stored
in the hold queue if:
- An infrastructure, such as a database, is unavailable.
- The message is damaged.
Refer to the WebSphere Business Process Management Information Center
topics on managing failed events for further details about the supported event
types.
