  • AUTOMATIC ADJUSTMENT OF AN EXECUTION PLAN FOR A QUERY
    Publication number: 20180046675
    Abstract: A DBMS optimizer generates a first query plan based on a first set of configuration parameters. The first query plan is executed in test mode one or more times. A first query object corresponding to the first query plan is created. The first query object includes the execution time of the first query plan. When the optimizer determines a first query plan is generated, a second query plan is generated based on a second set of configuration parameters. The second query plan is executed in test mode one or more times. A second query object corresponding to the second query plan is created. The second query object includes the execution time of the second query plan. Execution times of the first query plan and the second query plan are compared. The query plan with the shortest execution time is set as current query execution plan.
