Abstract: In a networked computer system that includes multiple interconnected nodes, a commitment control mechanism allows designating certain portions of a record in an in-memory database as mandatory and other portions of the record as secondary, and performs mandatory commitment control once all the mandatory portions are available even if one or more secondary portions are not yet available. The secondary portions may be under separate commitment control that is asynchronous to the commitment control for the mandatory portions, or may be under no commitment control at all. The result is a commitment control mechanism that performs commitment control for portions of a record that are marked mandatory even when one or more of the portions marked secondary are not available.

Abstract: An aspect-oriented system includes a way to access both local and remote advice that is consistent with the modularity concerns of an aspect-oriented program. During compilation of the aspect-oriented program, a weaver determines whether advice referenced by an aspect is local or remote. If the advice is local, the weaver applies the local advice to the base program. If the advice is remote, the weaver generates remote invocation code that may include client stubs and server code to handle the marshalling and unmarshalling of parameters. Invocations to the client stub are then inserted into the join points of the base program. At run-time, the server name and number that has the remote aspect is determined. When the client stub is invoked, the remote advice on the specified server may be accessed. The result is an improved weaver that may generate code to access remote advice in a different JVM.

Abstract: An apparatus and method define the concept of a “database breakpoint.” One or more conditions in the database are specified as a database breakpoint in a debug environment for debugging a computer program that accesses the database. When the database conditions exist, one or more debug functions may be performed with respect to the execution of the computer program. Examples of debug functions include halting execution of the computer program and halting operations to the database by other programs. With both the computer program and database halted, the user may then interrogate the database to determine its state, and may interrogate the program to determine its state. Database breakpoints greatly enhance the utility of a debugger by providing additional conditions for debugging a computer program that accesses a database.

Abstract: A content management system (CMS) includes a content modification mechanism that detects a change to a shared document in the repository, and in response to the detected change, inserts applicability metadata in the shared document. The content modification mechanism may broadcast the change to each parent document. Each parent document votes on whether or not to accept the change. If enough of the parent documents accept the change (i.e. the votes meet a defined voting threshold), the applicability metadata is removed from the shared content. If not enough of the parent documents accept the change, the applicability metadata remains in the shared content, and a profile corresponding to the applicability metadata is created for each parent document that accepted the change. In this manner, profiling may be used to account for changes to shared content in a content management system.

Abstract: A method and apparatus for a pull back optimizer in conjunction with an inventory management system allows for efficient retrieval of return assemblies for optimized parts fulfillment. The inventory management system includes a return assembly inventory and a list of parts needed for order fulfillment. The return assembly inventory lists the part numbers and quantities of parts in each return assembly. The pull back optimizer allows a user of the inventory management system to efficiently determine the optimal return systems to pull back to production for parts fulfillment to minimize the impact on those using the return assemblies.

Abstract: A graphical query interface provides visual feedback to a user during the construction of a query. In a first embodiment, the visual feedback helps the user determine the quality of the query as the query is being built. The relationship of columns in the database is graphically displayed to a user. When the user selects a column in the database, a filtered display mechanism displays only those columns or records that satisfy the portion of the query already constructed. In a second embodiment, the visual feedback eliminates some possible selections in the query tree due to previously-made selections that eliminate the eliminated selections as possibilities. In the second embodiment, the visual feedback mechanism may function according to data values in columns, and may also function according to known relationships between columns themselves.

Abstract: A database system has a contention monitor which determines when the level of contention for accessing or inserting records in the database rises above a threshold, and inhibits non-critical access to the database to reduce the level of contention. In a preferred embodiment, the level of contention is determined by periodically measuring the time for an INSERT operation on the database, and comparing the time to a threshold derived from a baseline time measurement for the operation during a time of normal database activity. Thus the contention level is inferred from the time to do the operation, in this case the INSERT query. In one embodiment, the contention monitor notifies a system administrator to take action to reduce the contention. In another embodiment, the contention monitor informs the system to take action automatically according to predetermined selections by the system administrator.

Abstract: A content management system (CMS) includes a component identification mechanism for identifying components in a component-centric way that takes into account specified conditions for a link location in a compound document as well as component relationships and conditions. By using the relationships and conditions, a more intelligent choice may be made when identifying components for a particular link location. The identifying of components for a given link location in a compound document may be used by the content management system when auto-population is enabled, and may be used by the content management system to provide a list of candidate components to a user when auto-suggestion is enabled.

Abstract: A movement-based filtering mechanism in a graphical user interface allows a user to filter search results by simply moving a pointer, such as a mouse. One or more attributes are displayed to the user in a graphical format. By selecting the pointer (such as clicking on a mouse button), the user may dynamically filter the search results according to the attribute(s) under the pointer. Weighting of multiple attributes may be performed according to the time the pointer spends in each attribute area in the display, or according to a path length of the pointer in each attribute area in the display. In addition, the speed of the dynamic filtering may be directly controlled according to the speed of the movement of the pointer. A timeline may also be displayed that allows the user to go back to any suitable point in time in the filtering process.

Abstract: A content management system (CMS) allows defining multi-element burst rules that allow multiple elements to be bursted to a single object. A multi-element burst mechanism performs the bursting of multiple elements when a multi-element burst rule is processed. A multi-element burst policy allows a user to specify conditions that govern the function of the multi-element burst mechanism. The result is a CMS that includes multiple elements in a single object, thereby enhancing reusability of content in the CMS.

Abstract: A memory controller performs a mirror copy function in a way that allows processor accesses to memory to continue during the mirror copy operations that make up the mirror copy function. Data integrity of mirror copy operations is assured by protocols set up in the memory controller. The result is a memory controller that performs a mirror copy function in a way that allows normal processor accesses to memory to be interleaved with mirror copy operations, thereby minimizing the impact on system performance of executing the mirror copy function.

Abstract: A design structure for a high speed computer processor system includes a high speed interface for a graphics processor. In a preferred embodiment, the high speed interface includes a front side bus (FSB) that interfaces to a similar high speed interface on the graphics processor.

Abstract: A query processor includes a HAVING clause processing mechanism that processes the HAVING clause in a query when generating the intermediate results, instead of generating the intermediate results without regard to the HAVING clause, then applying the HAVING clause to the intermediate results. As a result, the size of the intermediate results may be significantly reduced, and effort is not wasted in placing data into the intermediate results in one step that would be removed were the HAVING clause processed separately.

Abstract: In a computer system that includes multiple processors, each processor in a computer system is assigned a processor class. Processor capacity and usage are monitored according to the class assigned to the processor. Capacity and usage are reported on a class-by-class basis so that the capacity and performance of different classes of processors are not erroneously compared or summed. The capacity and usage are monitored and reported in an abstract unit of measurement referred to as a “CPU time unit”. Processors of the same type that run at different clock speeds or that have different internal circuitry enabled are preferably assigned the same class, with one or more conversion factors being used to appropriately scale the performance of the processors to the common CPU time unit for this class.

Abstract: A memory controller optimizes execution of a read/modify/write command by breaking the RMW command into separate and unique read and write commands that do not need to be executed together, but just need to be executed in the proper sequence. The most preferred embodiments use a separate RMW queue in the controller in conjunction with the read queue and write queue. In other embodiments, the controller places the read and write portions of the RMW into the read and write queue, but where the write queue has a dependency indicator associated with the RMW write command in the write queue to insure the controller maintains the proper execution sequence. The embodiments allow the memory controller to translate RMW commands into read and write commands with the proper sequence of execution to preserve data coherency.

Abstract: A quorum-based server power-down mechanism allows a manager in a computer cluster to power-down unresponsive servers in a manner that assures that an unresponsive server does not become responsive again. In order for a manager in a cluster to power down servers in the cluster, the cluster must have quorum, meaning that a majority of the computers in the cluster must be responsive. If the cluster has quorum, and if the manager server did not fail, the manager causes the failed server(s) to be powered down. If the manager server did fail, the new manager causes all unresponsive servers in the cluster to be powered down. If the power-down is successful, the resources on the failed server(s) may be failed over to other servers in the cluster that were not powered down. If the power-down is not successful, the cluster is disabled.

Abstract: A deployable seating platform preferably includes a base configured for attachment to a horizontal surface, such as the underside of a swimming platform on a boat. The base is coupled to a slide and pivot mechanism, which is coupled to a first end of an elongated member, with the second end of the elongated member coupled to a seat. The slide and pivot mechanism allows the elongated member to slide and pivot from a non-deployed position to a deployed position and allows the elongated member to slide and pivot from the deployed position to the non-deployed position. When in the non-deployed position, the deployable seating platform is out of the water and out of the way under the swimming platform. When in the deployed position, the seat of the deployable seating platform is in the water, providing a place for a person to sit in the water.
