When a job operation fails, one or more events may be generated. These can be viewed through any of the interfaces to Oracle VM Manager and are displayed in the user interface as flagged with yellow or red icons in the navigation tree. If an object has an error event associated with it you must resolve the issue that caused the event and then acknowledge the event to clear the error and notify Oracle VM Manager that the object is able to resume normal operations. For example, this can occur if an Oracle VM Server or virtual machine is stopped as a result of an error. Alternatively, events may be generated if a network goes down due to a hardware issue affecting either a switch or a network interface card. Oracle VM Servers, virtual machines, repositories and storage objects can have error events associated with them.

Note that often an event may be generated as the result of a problem outside of Oracle VM Manager. You should only acknowledge an event when you are certain that the problem that initially triggered the event has been resolved. If you acknowledge and event and the problem has not been resolved, Oracle VM Manager may continue with any remaining jobs that may have been blocked by the event. This can make it more difficult to roll back the environment and may result in further errors occurring.

To acknowledge events, see the object's Events perspective in Events Perspective in the Oracle VM Manager User's Guide.
