    摘要: A method of processing a transaction includes processing a transaction workload in a primary process pair on a first node in a cluster of nodes, the processing using at least one stable storage volume for storing a database and another stable storage volume for storing a log, the at least one stable storage volume and the log storage volume forming a log storage group. The method further includes performing checkpointing operations via the network from the primary process pair to a backup process pair while processing the transaction workload, the backup process pair operating on a second node in the cluster of nodes. The method further includes detecting a failure making the first node inoperable or inaccessible, and after detecting the failure, engaging the backup process pair to take over the transaction processing workload of the primary process pair, the backup process pair being configured to operate with the log storage group used by the primary process pair on the failed node.

    摘要: A method of transferring a transaction workload of a primary process pair. The primary pair has access to a stable storage volume for storing data items and a log for storing transaction processing updates to data items. A backup process pair is established for the primary pair and information is transferred thereto so that it can take over for the primary pair should that pair fail. Additionally, a lock table is maintained and update records are written to the log by the primary pair. The update records include any locks from the lock table that related to the update records. When a failure of the primary pair occurs, the storage volume is locked, and the backup pair reads the log to reconstruct a lock table. Once the locks have been reconstructed, the lock on the storage volume is released and the backup pair operates to process the workload.

    摘要: Provided is a generic framework for resource modeling to assist in scheduling tasks. More specifically the model provides a structure and method for receiving a task having at least one resource requirement. Upon receipt of such a task, a set of compliant resources are retrieved. A graph is generated to indicate one or more resource paths, each path running through a subset of the compliant resources. Each resource is represented as a node on the graph, and each resource has at least one characteristic. A characteristic common to all nodes on each path is then selected and plotted upon a continuum. Each path is then evaluated to determine path viability. Path viability is indicated by a common intersection upon the continuum of the selected characteristic for all nodes along the path.

    摘要: A low profile, wide belt mobilized bridge carrier is used in low vein mining operations. The mobilized bridge carrier of the present invention includes a carrier frame that carries the propulsion system and that supports the receiving boom, the discharge boom, the cab assembly and the canopy. The preferred mobilized bridge carrier is track propelled, and includes at least a pair of crawler track assemblies which are actuated by an electrically operated hydraulic motor. The receiving boom and the discharge boom are pinned together and each are pivotally mounted on carrier frame at a main pivot point. The carrier frame is of reinforced construction. The receiving boom and discharge boom of the present invention include low profile side panel assemblies which allow the present mobilized bridge carrier to be used in "low vein" mining applications. In order to compensate for any inherent loss of strength in the receiving boom that results from lowering the profile to accomplish its purpose of operating within low veins, the present receiving and discharge booms incorporate certain novel reinforcements, including inside reinforcement plates that extend substantially throughout the length of the booms and which is constructed of a plate of T1 steel approximately three/fourths of an inch to approximately one inch thick continuously welded to the interior of each of the sides of the booms.
