    摘要: A method and system for storing one or more database query language statements and performance information for each query language statement as a persistent database object. In one or more embodiments, the method and system stores the resource intensive statements and the performance information for each resource intensive statement as a second persistent database object.

    摘要: Techniques are provided for automatically recommending alternative execution plans for a SQL statement. Information pertaining to one or more execution plans for a SQL statement can be retrieved from a set of plan sources. The one or more execution plans can include the current execution plan for the statement and one or more historical execution plans. Based on the retrieved information, the performance of the one or more execution plans can be compared to each other. Based on the comparison, a recommendation can be provided to a user indicating that a particular execution plan (e.g., a historical execution plan) should be used in place of the current execution plan to execute the SQL statement.

    摘要翻译: 提供了技术来自动推荐SQL语句的替代执行计划。 有关SQL语句的一个或多个执行计划的信息可以从一组计划源中检索。 一个或多个执行计划可以包括该语句的当前执行计划和一个或多个历史执行计划。 基于检索到的信息,可以将一个或多个执行计划的性能彼此进行比较。 基于该比较,可以向用户提供指示使用特定执行计划(例如,历史执行计划)来​​代替执行SQL语句的当前执行计划的建议。

    摘要: Techniques are provided for a fully-automated process for tuning database query language statements that selects database query language statements for tuning, tunes the database query language statements and generates tuning recommendations, tests the tuning recommendations, and determines whether to implement the tuning recommendations based on the test results. The fully-automated tuning process may also automatically implement certain tuning recommendations and monitor the performance of the database query language statements for which tuning recommendations have been implemented.

    摘要: Systems, methods, and other embodiments associated with test execution of user SQL in server code are described. One example method includes producing a reproduced execution environment that reproduces a portion of an execution environment in which a user SQL runs. The example method may also include running the user SQL in the reproduced execution environment and capturing a statistic associated with performance of the user SQL while the user SQL runs in the reproduced execution environment. The method may conclude by storing, displaying, and/or providing a signal concerning the statistic.
