    • A method, system and article of manufacture for processing a database query result that includes multiple data elements in a single result field. One embodiment provides a method of processing a query result. The method includes receiving a query result that includes at least one result field having multiple data elements that are in a many-to-one relationship with a second result field. The received query result is parsed to identify the multiple data elements from the first result field. Then, a result set is generated on the basis of the identified multiple data elements. The generated result set only includes one-to-one relationships between different result fields. Advantageously, the generated result set is suitable for programmatic access in order to allow an automated processing of the generated result set.

    • Embodiments of the invention provide techniques for optimizing the processing of abstract rules included in rule set containers. In one embodiment, a first abstract rule may be identified as having an effect on a second abstract rule of the rule set container. A predicate and an action of the first abstract rule may be used in translating the second abstract rule into an executable rule. The executable rule performs the functionality included in the first and second abstract rules, while only requiring one rule execution in a rule engine. In another embodiment, the first abstract rule may be translated into a rejection query configured to return a rejection set. The second abstract rule may be translated into an executable rule that includes a condition that excludes any records included in the rejection set.
    • 本发明的实施例提供了用于优化规则集容器中包括的抽象规则的处理的技术。 在一个实施例中,第一抽象规则可以被识别为对规则集容器的第二抽象规则具有影响。 可以将第一抽象规则的谓词和动作用于将第二抽象规则转换为可执行规则。 可执行规则执行包含在第一和第二抽象规则中的功能,而只需要规则引擎中的一个规则执行。 在另一个实施例中,第一抽象规则可以被转换成被配置为返回拒绝集合的拒绝查询。 第二抽象规则可以被翻译成可执行规则,其包括排除包含在拒绝集合中的任何记录的条件。

    • An apparatus, program product and method utilize policy-driven management of a pool of cursors in a database management system. Cursor usage statistics are determined for a plurality of cursors, and a plurality of cursor criteria defined in a policy are used to identify one or more cursors to close based upon the determined statistics. Among the statistics that are collected is a query time statistic that specifies, for each cursor, how long the query with which that cursor is associated, took to execute. As a result, a cursor that is associated with query that took a relatively longer time to execute will generally be less likely to be closed than a cursor that is associated with a query that took a relatively shorter time to execute. Consequently, should a cursor be needed for a particular query after the cursor has been closed, the performance penalty associated with recreating that cursor and its associated objects will be reduced.
    • 设备,程序产品和方法利用数据库管理系统中的游标池的策略驱动管理。 针对多个光标确定光标使用统计信息,并且在策略中定义的多个光标标准用于基于所确定的统计量来识别要关闭的一个或多个光标。 收集的统计信息是一个查询时间统计量,它为每个游标指定与该游标相关联的查询执行多长时间。 因此,与执行相对较长时间的查询相关联的游标通常比与执行相对较短时间的查询相关联的游标不太可能被关闭。 因此,如果在游标已经关闭之后,如果特定查询需要游标,则会减少与重新创建该游标及其关联对象相关联的性能损失。
