About parameter "DEFAULT_EXECUTION_TYPE" in dbms_sqltune.set_tuning_task_parameter
The usage of DEFAULT_EXECUTION_TYPE of set_tuning_task_parameter in document is: DEFAULT_EXECUTION_TYPE: the task defaults to this type of execution when none is specified by the EXECUTE_ TUNING_TASK Function and Procedure But it did not point out the possible values for this parameter. Anyone knows?
