Abstract: A method, computer program product, and system are provided for accelerating a query in a database system. For example, an embodiment of the method may include generating a data structure identifying a set of rows that satisfy conditions local to a table prior to an evaluation of a query and modifying the query based on the data structure. In addition, the method may include repeating the steps with respect to generating the data structure and modifying the query, if one or more additional local conditions are inferred from modifying the query based on the data structure.

Abstract: A system, method, and computer program product for monitoring managed resources by subscribing to broadcast notifications relayed by a Java Management Extensions (JMX) message bridge between JMX managed beans (JMX MBeans) and a client application with user interface (UI) components. In an embodiment, ADOBE™ FLEX™ user UI components subscribe to JMX broadcast notifications. The method generates messages destined for UI components using a JMX broadcaster. JMX MBeans are created in a JMX server and are subscribed to JMX broadcasts. The JMX MBeans are created with filter values identifying destination UI components. A JMX managed object name is passed to the UI during the creation of the UI components. The UI components become consumers of a message topic. A JMX message adapter dedicated to the communication with the JMX MBeans receives JMX broadcast notifications. Messages generated by the JMX broadcaster are relayed to the destination UI components through the JMX MBeans.

Abstract: The present invention provides a method for obtaining predicable and repeatable output results in a continuous processing system. The method involves processing messages and primitives in accordance with the following rules: (1) Messages are processed in accordance with timestamps, where messages are divided up into “time slices”; (2) message order within a data stream is preserved among messages with the same time stamp; (3) subject to rule #4, for each time slice, a primitive is executed when either the messages within such time slice show up in the input stream for such primitive or the state of the window immediately preceding such primitive changes due to messages within such time slice; and (4) for each time slice, primitives that are dependent on one or more upstream primitives are not executed until such upstream primitives have finished executing messages in such time slice that are queued for processing.

Abstract: Systems, methods, computer program product embodiments for representing markup language document data in a searchable format in a database system are provided. An embodiment includes parsing a markup language document into a data stream, the data stream including a plurality of fields in a predefined format having a symbol table for at least one field of the data stream, and optimized field size based on a maximum value of data within each field, and storing the data stream in data storage.

Abstract: Reducing contentions between processes or tasks that are trying to access shared resources is described herein. According to embodiments of the invention, a method of writing a set of data associated with a task to a memory resource is provided. The method includes calculating the amount of memory required to write said data to the memory resource and updating an expected end marker to reflect the amount of memory required to write the data to the memory resource. A flag is then set to an incomplete state, and the data is written to the memory resource. The flag can be set to a complete state and an end marker is updated. The end marker indicates the end of the data stored in the memory resource.

Abstract: Embodiments of a system, method, and computer program product for monitoring task processing in a distributed system are provided. A task controller is provided with a task. The task controller generates a plurality of subtasks from the provided task, where each subtask includes a callback function. The subtasks are distributed for execution to multiple computing devices in the distributed system. As each subtask is executed by a computing device, the callback function is invoked, the invocation generating a message. The message includes the process and status information of the executing subtasks. The process and status information included in the message for each subtask is monitored, analyzed and aggregated, and is transmitted for a display on a client device.

Abstract: A hierarchical entitlement system with integrated inheritance and limit checks is described.

Abstract: Methods, apparatus and computer program products for storing a recurring time-scheduled data record in a calendaring application that does not support a pattern of recurrence of the record are described herein. The method includes the steps of: 1) receiving from a server, the recurring time-scheduled data record having a first recurrence pattern; 2) determining whether the first recurrence pattern is supported by the calendaring application; 3) if the pattern is not supported, then selecting a closest recurrence pattern supported by the calendaring application; 4) modifying the selected closest recurrence pattern by applying recurrence exceptions to create a second recurrence pattern; 5) modifying the recurring time-scheduled data record based on the second recurrence pattern to create a supported record; and 6) transferring the supported record to the calendaring application.

A specialized result form of the generic data structure is also provided and utilized to manage generated exceptions of the data exchanges.

Abstract: Embodiments include a method, apparatus and computer program product for executing a database transaction in parallel using subtransactions. The method includes receiving a transaction at an application, the transaction having a first statement and a second statement, and determining whether operation of the first statement is independent from operation of the second statement.

The method further includes executing the subtransactions using resources of the database. Finally, when execution of all of the subtransactions have successfully completed, committing all of the subtransactions.
