DBMS_ADVISOR.create_task (
advisor_name => 'ADDM',
task_name => '970_1032_AWR_SNAPSHOT',
task_desc => 'Advisor for snapshots 970 to 1032.');
-- Set the start and end snapshots.
DBMS_ADVISOR.set_task_parameter (
task_name => '970_1032_AWR_SNAPSHOT',
parameter => 'START_SNAPSHOT',
value => 970);
DBMS_ADVISOR.set_task_parameter (
task_name => '970_1032_AWR_SNAPSHOT',
parameter => 'END_SNAPSHOT',
value => 1032);
-- Execute the task.
DBMS_ADVISOR.execute_task(task_name => '970_1032_AWR_SNAPSHOT');
END;
-- Display the report.
