In this post, I will explain How to create ADDM task  and check its report
We are using start snapshot as 900
And end snapshots as 950

BEGIN
— Create an ADDM task.
DBMS_ADVISOR.create_task (
advisor_name      => ‘ADDM’,
task_name         => ‘900_950_AWR_SNAPSHOT’,
task_desc         => ‘Advisor for snapshots 900 to 950.’);
— Set the start and end snapshots.
DBMS_ADVISOR.set_task_parameter (
task_name => ‘900_950_AWR_SNAPSHOT’,
parameter => ‘START_SNAPSHOT’,
value     => 900);
DBMS_ADVISOR.set_task_parameter (
task_name => ‘900_950_AWR_SNAPSHOT’,
parameter => ‘END_SNAPSHOT’,
value     => 950);
— Execute the task.
DBMS_ADVISOR.execute_task(task_name => ‘900_950_AWR_SNAPSHOT’,);
END;
/
— Display the report.
SET LONG 100000
SET PAGESIZE 50000
SELECT DBMS_ADVISOR.get_task_report(‘900_950_AWR_SNAPSHOT’) AS report
FROM   dual;
SET PAGESIZE 24
