摘要： Techniques are provided for isolating faults in a software program by providing at least two code paths that are capable of performing the same operation. When a fault occurs while the one of the code paths is being used to perform an operation, data that indicates the circumstances under which the fault occurred is stored. For example, a fault-recording mechanism may store data that indicates the entities that were involved in the failed operation. Because they were involved in an operation that experienced a fault, one or more of those entities may be “quarantined”. When subsequent requests arrive to perform the operation, a check may be performed to determine whether the requested operation involves any of the quarantined entities. If the requested operation involves a quarantined entity, a different code path is used to perform the operation, rather than the code path from which the entity is quarantined.

摘要： Various embodiments of the invention provide solutions that can offer a consistent framework for tools that assist in the configuration, tuning, and/or troubleshooting of a database and/or an RDBMS. Merely by way of example, one set of embodiments provides a software framework for an advisor component of a database and/or RDBMS. In accordance with some embodiments, the framework might specify a common data model for such advisor components. The data model can include, merely by way of example, a set of one or more findings (which might, in some cases, describe the result of an analysis of a circumstance in the database, RDBMS, and/or a mid-tier application used with the database) and/or a set of one or more recommendations (which might provide suggestions for addressing the circumstance). In particular embodiments. In particular embodiments, the data model might include a set of on or more rationales, which can explain the recommendations. In some cases, the software framework might include a task associated with the advisor component and/or one or more interfaces, which can include, inter alia, user interfaces and/or APIs. Other sets of embodiments can provide methods, systems and/or software programs for implementing an advisor framework.
摘要翻译：本发明的各种实施例提供可以为协助数据库和/或RDBMS的配置，调整和/或故障排除的工具提供一致的框架的解决方案。仅仅作为示例，一组实施例为数据库和/或RDBMS的顾问组件提供了软件框架。根据一些实施例，框架可以为这种顾问组件指定公共数据模型。数据模型可以仅包括一个或多个发现（在某些情况下可能描述数据库中的情境分析的结果，RDBMS和/或中间层应用程序）与数据库一起使用）和/或一组一个或多个建议（可能提供解决情况的建议）。在特定实施例中，数据模型可以包括一组或多个理由，其可以解释建议。在一些情况下，软件框架可以包括与顾问组件和/或一个或多个接口相关联的任务，其特别可以包括用户界面和/或API。其他实施例集合可以提供用于实现顾问框架的方法，系统和/或软件程序。

摘要： A method and apparatus for debugging a software program is provided that is non-intrusive and allows multiple persons to debug concurrently in view private sessions. In one example, a method includes preserving a memory state of a portion of a software program, such as a database system. A second software program is compiled and dynamically linked, and which when executed, would normally cause modification to targeted data in the preserved portion of the software program. The second software program is executed by making a copy of the targeted data in the preserved portion of the software program. The copy is modified to generate a modified copy of the targeted data without modifying the data that is in the preserved portion of the software program. In subsequent accesses, the user that issued that executed the second software program accesses the modified copy whenever the user would have otherwise accessed the corresponding preserved portion. The second software program is made accessible to other users of the database system by publishing in the preserved portion a corresponding symbolic name associated with the second software program. If another user accesses the second software program and executes it, then another copy of the targeted data is made for that user. As before the copy is modified to generate a modified copy of the targeted data without modifying the data that is in the preserved portion of the software program.

摘要： A method and apparatus for using undo/redo logging to perform asynchronous updates of parity and data pages in a redundant array data storage system is disclosed. The computer-implemented apparatus includes, 1) a redundant array data storage system having a plurality of data pages and a corresponding parity page residing therein, each page of the plurality of data pages and the parity page containing version information indicating a version of content in the page, 2) a memory-resident plurality of data pages corresponding to the plurality of data pages residing in the redundant array data storage system, 3) a data log retaining modification information defining any differences between content of the memory-resident plurality of data pages and content of the plurality of data pages residing in the redundant array data storage system, and 4) control logic for deferring modification of the parity page following modification of one of the plurality of data pages. The control logic further includes control logic for re-creating content of one of the plurality of data pages or the parity page by applying the modification information in the data log to the memory-resident plurality of data pages.
