摘要： Systems, methods, and other embodiments associated with hybrid optimization strategies in automatic SQL tuning are described. One example method includes receiving a first (e.g., cost-based) execution plan for a user structured query language statement (User SQL) from a first (e.g., cost-based) optimizer. The example method may also include receiving a second (e.g., rules-based) execution plan for the User SQL from a second, different (e.g., rules-based) query optimizer. The method may include identifying a preferred execution plan based on data produced by test executing the execution plans in a reproduced execution environment that reproduces at least a portion of an execution environment in which the user SQL runs. The method may also include controlling a database to execute the User SQL using the preferred execution plan.

摘要： Techniques for automatically recommending parallel execution of a SQL statement. In one set of embodiments, a first determination can be made regarding whether a SQL statement can be executed in parallel. Further, a second determination can be made regarding whether executing the SQL statement in parallel is faster than executing the statement in serial by a predetermined factor. If the first determination and second determination are positive (i.e., the statement can be executed in parallel and parallel execution is faster by the predetermined factor), a recommendation can be provided indicating that the SQL statement should be executed in parallel. In some embodiments, the recommendation can include a report specifying the degree of performance improvement gained from parallel execution, additional system resources consumed by parallel execution, and other statistics pertaining to the recommended parallel execution plan.

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.
