Selecting during a system shutdown procedure, a restart incident checkpoint of an incident analyzer in a distributed processing system

摘要

Methods, apparatuses, and computer program products for selecting during a system shutdown procedure, a restart incident checkpoint of an incident analyzer in a distributed processing system. Embodiments include the incident analyzer determining whether at least one incident is in a queue. If at least one incident is in the queue, the incident analyzer selects as the restart incident checkpoint, a last incident completed checkpoint. If at least one incident is not in the queue, the incident analyzer determines whether the last incident completed checkpoint matches a last incident analysis pool selection checkpoint. If the last incident completed checkpoint matches a last incident analysis pool selection checkpoint, the incident analyzer selects as the restart incident checkpoint, a monitor checkpoint. If the last incident completed checkpoint does not match the last incident analysis pool selection checkpoint, the incident analyzer selects as the restart incident checkpoint, the last incident completed checkpoint.

1. A method of selecting during a system shutdown procedure, a restart incident checkpoint of an incident analyzer in a distributed processing system, the restart incident checkpoint identifying an incident for the incident analyzer to use upon restart of the incident analyzer, the incident analyzer including an incident analysis pool and an incident receive queue to provide incidents to the incident analysis pool, the method comprising:
determining during the system shutdown procedure, by the incident analyzer, whether at least one incident is in the incident receive queue; if at least one incident is in the incident receive queue, selecting as the restart incident checkpoint, a last incident completed checkpoint; and if at least one incident is not in the incident receive queue:
determining whether the last incident completed checkpoint matches a last incident analysis pool selection checkpoint;if the last incident completed checkpoint matches the last incident analysis pool selection checkpoint, selecting as the restart incident checkpoint, a monitor checkpoint; andif the last incident completed checkpoint does not match the last incident analysis pool selection checkpoint, selecting as the restart incident checkpoint, the last incident completed checkpoint.
