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.
- WebSphere MQ failed events. In the context of WebSphere MQ, a
failed event is generated when there is a problem (such as a data-handling
exception) in the WebSphere MQ or WebSphere MQ JMS binding export
or import used by an SCA module.
- (WebSphere Process Server only) 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
- (WebSphere Process Server only) 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.
