Abstract: Tire traction is dynamically increased in a vehicle by performing a sequence of steps. The vehicle includes a controllable suspension having a damper, a spring, and an active element, a suspension controller, and a controllable aerodynamic element. The body of the vehicle is positioned at a level which allows for a predetermined amount of upward suspension travel. The suspension controller receives a trigger after the body of the vehicle is positioned at a level which allows for a predetermined amount of upward suspension travel. The suspension controller generates a first control signal upon receipt of the trigger. The first control signal is sent to the active element to generate the positive impulse. The positive impulse causes application of force to the wheel of the vehicle in a downward direction, thereby dynamically increasing tire traction.

Abstract: Actions are performed on data in databases of a multi-node system. Each node includes an indicia engine and each node has access to a respectively associated database. Each of the databases has a first subset of data that match each other and which are kept in synchronization with each other. At least one of the databases has a second subset of data that intentionally does not match a subset of data in at least one of the other databases and which is not kept in synchronization with the at least one of the other databases. In operation, each node receives a plurality of matching requests to perform an action on data in the database associated with each node. The indicia engine at each node computes, for each of the matching requests, indicia of results of the action performed on data in the database associated with each node.

Abstract: A method and system are provided for comparing a first database table and a second database table with each other to produce a table of differences therebetween. The first database table and the second database table include one or more subsets of data that are intended to match each other, and the first database table and the second database table each include multiple rows. Indicia is generated for each of the multiple rows of a subset of the first database table, and each of the multiple rows of a subset of the second database table. The generated indicia for each of the multiple rows of the subset of the first database table are compared with the generated indicia for the subset of each of the multiple rows of the subset of the second database table, on a row-by-row basis, wherein the comparing occurs without regard to an original order of the rows in either the first database table or the second database table.

Abstract: An automated method and apparatus are provided for comparing a first database and a second database that are intended to be kept in synchronization with each other. Applications process changes that are posted to the first database and the second database. Changes made to the first database are applied to the second database, and vice-versa. Changes made to the first database resulting from changes posted to the first database are collected into a first change log. Changes made to the second database resulting from changes posted to the second database are collected into a second change log. Representations of the changes that correspond to the same respective changes in the change logs are compared with each other. Corrective action is performed when the comparison indicates that the corresponding representations of the changes in the first change log and the second change log do not match.

Abstract: A method is provided for performing transaction processing in a system. The system includes a plurality of nodes. Each node in the system includes a processor, an application executing in the processor, and a local queue. Each node executes multiple user transactions. Each transaction includes a BEGIN step, and one or more data manipulation language (DML) or data definition language (DDL) operations. In operation, two of the nodes are selected to receive the same user request to process the transaction. The processor at each of the two nodes executes in the application the same user request to process the transaction. Local indicia is created at each of the two nodes from the outcome of the transaction steps and operations of the transaction and is then exchanged with the other of the two nodes. The processor at each of the two nodes puts on their respective local queues the local indicia created at the same node as the processor, and the local indicia received from the other of the two nodes.

Abstract: Output responses corresponding to a plurality of matching user requests are combined in a transaction response combiner (TRC). Each output response includes response details. The TRC receives an output response for each of the user requests. Each output response is tagged with an identifier that corresponds with the respective user request. It is detected when an output response received at the TRC has one or more corresponding output responses by searching in the memory for output responses that have the same tag. Rules of a rules engine are applied to combine the output responses received at the TRC for each of the matching user requests into a final output response. The rules of the rules engine are applied to the corresponding output responses with the same tag, and to the response details for the output response that shares the same detected tag. The final output response is outputted by the TRC.

Abstract: Methods are disclosed for controlling access to a resource that is accessible to multiple nodes in a multi-node system or multiple processors in a multi-processor system. In operation, each node or processor receives a matching request to access the resource. Indicia of the request to access the resource is computed at each node or processor and is then compared between nodes or processors. Access to the resource is given to a node or processor when the computed indicia matches.

Abstract: A method is provided for validating transactions in a system that includes indeterministic ordering of change log events by using deterministic indicia. The system includes a plurality of nodes. Each node in the system includes an instance of a database used by an application, and a change log associated with the instance of the database used by the application. Each node executes transactions. Each transaction has a plurality of subsets including one or more data manipulation language (DML) or data definition language (DDL) operations. Results of the DML or DDL operations are stored in the change log as change log events, wherein the order of the change log events stored in the change log on one node is in a different order than the order of change log events stored in the change log of at least one of the other nodes. For each subset of a transaction executing at each node, deterministic subunits of the change log events are defined. Indicia are then computed for each subunit of the change log events.

Abstract: An apparatus is provided for resolving an unintended transaction rollback in a system that includes an audited database, a non-audited application, and a facility for converting non-audited applications to use audited database transactions, wherein the unintended transaction rollback is the result of a failure of the facility to convert the unintended transaction rollback to a commit operation, The non-audited application is operated with the facility creating database transactions against the audited database. The database transactions include one or more transaction steps or operations. The created database transactions are monitored to detect transaction rollbacks. A determination is made when a detected transaction rollback for a database transaction is an unintended transaction rollback. The one or more transaction steps or operations of the database transaction that included the unintended transaction rollback are recovered in the audited database.

Abstract: Tire traction is dynamically increased in a vehicle by performing a sequence of steps. First, a center of mass of the body of the vehicle is raised by a predetermined amount above a base level by using an active element of a controllable suspension to generate the positive forces in response to a first signal from a suspension controller. Second, the suspension controller receives a trigger after the center of mass of the body of the vehicle is raised by the predetermined amount above the base level. Third, at least some of the generated positive forces of the active element are removed upon receipt of the trigger in response to a second signal from the suspension controller. The removal of the at least some of the generated positive forces of the active element results in the center of mass of the body of the vehicle dropping back towards the base level and increasing a load on the controllable suspension, thereby dynamically increasing tire traction.

Representations of the before images of changes made to records or rows of the source database are compared with representations of the current images of records or rows of the target database that correspond to the before images of changes made to records or rows of the source database.

Abstract: A method is provided for performing transaction processing in a system. The system includes a plurality of processors. Each processor executes a plurality of transactions. Two of the processors receive requests to process the same subset of the plurality of transactions and each of the two processors execute each of the requests to process the same subset of the plurality of transactions. Each of the two processors create local indicia from the outcome of each transaction in the same subset of the plurality of transactions. Each of the two processors assign a transaction tag to each of the local indicia, wherein the same transaction tag is assigned by each of the two processors executing the same transaction. The local indicia and the respectively assigned transaction tags from each of the two processors are queued. It is then detected when queued transaction tags from the two processors match each other. The local indicia associated with the matching transaction tags are then compared to each other.
