摘要： An improved method, apparatus, and computer instructions for identifying a memory leak in a heap. Prior to the start of the observation period, all live objects in the heap are identified to form a set of live objects by altering an indicator in the live objects. After running the system for the required amount of time or until completion of the event being monitored, the system is used to obtain the list of live objects without the altered indicator. Live objects without the altered indicators form the most likely objects associated with a memory leak.

摘要： A method and apparatus for identifying a minimum call tree data structure from a plurality of call tree data structures are provided. With the apparatus and method, call tree data structures are generated for two or more executions of a build of a computer program. The apparatus and method perform a “tree-minimization” operation in which the two or more call trees generated during runs of the computer program are walked and only those nodes that are present in each of the tree data structures are maintained in a minimized tree data structure. In addition, the minimum values for these common nodes are maintained in the minimized tree data structure. In this way, asynchronous events are removed from the minimum tree data structure and analysis may focus on those areas of the computer program that are consistent between runs of the computer program.

摘要： A method and apparatus for automatically performing regression processing on trace data are provided. With the apparatus and method, call tree data structures are generated for two or more executions of two or more builds of a computer program. The apparatus and method perform a “tree-minimization” operation on each set of call tree data structures for each of the builds to generate minimized call tree data structures for each build of the computer program. The minimized call tree data structures are then subtracted from one another to generate a subtracted minimized call tree data structure. From this subtracted minimized call tree data structure, the portions of the computer program that are different from build to build and which appreciably and consistently affect the difference in execution of the computer program from build to build may be identified. Thus, the analyst's attention is directed to these areas of the computer program code which may be optimized in order to obtain better execution of the computer program.
摘要翻译：提供了一种用于自动执行跟踪数据的回归处理的方法和装置。利用该设备和方法，生成两个或更多个计算机程序构建的两个或多个执行的调用树数据结构。该装置和方法对每个构建的每一组呼叫树数据结构执行“树最小化”操作，以便为计算机程序的每个构建生成最小化的调用树数据结构。然后将最小化的呼叫树数据结构从彼此中减去以产生减去最小化的呼叫树数据结构。从该减去的最小化调用树数据结构中，可以识别与构建构建不同的计算机程序的部分以及显着和一致地影响计算机程序从构建到构建的执行差异的部分。因此，分析师的注意力是针对计算机程序代码的这些区域，其可以被优化以便获得更好的计算机程序的执行。

摘要： A method, apparatus, and computer instructions in a processor for performing arithmetic operations. A data type associated with a particular memory location is used to determine if an operation about to be performed on the data in that location is legal. If the operation requires the data to have a required data type, a determination is made as to whether the operation is a legal operation based on the identified data type and the required data type. If the operation is not legal on the identified type, a determination is made as to whether data can be cast to change the identified data type to the required data type. The data is cast to the required data type if the data can be cast to form modified data, and the arithmetic operation is performed on the modified data. If the data cannot be cast to the Required type, an exception or interrupt is generated.

摘要： A method, apparatus, and computer instructions for generating coverage data during execution of code in the data processing system. During execution of the code, a determination is made as to whether an access indicator is associated with an instruction in response to executing the instruction in the code by a processor in the data processing system. If the access indicator is associated with the instruction, a state of the access indicator is changed, by the processor, when the instruction is executed. In this manner, coverage data for executed instructions is generated by the processor during execution of the code.

摘要： A business integration (BI) system receives business objects from a source application at an event partitioner. Event partitioner partitions received business objects into independent sets based on interdependent events, and allocates each independent group of business events to a separate event queue based a partitioning modulo reduction transformation of the independent sets to determine the correct event queue for storing a particular received business object. This transformation reduces the number of independent sets to a number of event groups equal to the number of allocated event queues. Events in different groups are delivered to an interchange server through the separate event queues so that they may be processed independently and in parallel, thus improving the overall performance of the interchange server, while guaranteeing that dependent events are processed in the correct serial order.
摘要翻译：业务集成（BI）系统从事件分割器的源应用程序接收业务对象。事件分割器根据相互依赖的事件将业务对象分成独立的集合，并且通过独立集合的分区模数减少转换来将每个独立的业务事件组分配给单独的事件队列，以确定用于存储特定接收到的业务对象的正确事件队列。该转换将独立集合的数量减少为等于分配的事件队列数的多个事件组。不同组中的事件通过单独的事件队列发送到交换服务器，以便它们可以独立和并行处理，从而提高交换服务器的整体性能，同时保证以正确的顺序处理依赖事件。
