Create a job associated window, it failed.

Question

I use the window feature to control the job stop at a certain time. After create the job, I will set attribute 'stop_on_window_close' true to implement. However, when I create the job, it occured the error. The operation is below:
BEGIN
dbms_scheduler.create_window(window_name => 'TEST_WIN',
resource_plan => NULL,
start_date => sysdate,
repeat_interval =>'freq=daily;interval=1;byhour=17;byminute=30;bysecond=0' ,
duration => INTERVAL '3' MINUTE);
END;
BEGIN
dbms_scheduler.create_job(job_name => 'TEST_JOB',
schedule_name => 'TEST_WIN',
job_type => 'PLSQL_BLOCK',
job_action => 'begin dbms_lock.sleep(300); end;',
enabled =>TRUE,
auto_drop => FALSE);
END;
ORA-27481: "DPS2.TEST_JOB" has an invalid schedule
ORA-27476: "DPS2.TEST_WIN" does not exist
SQL> select window_name,enabled from all_scheduler_windows where window_name='TEST_WIN';
WINDOW_NAME ENABLED
TEST_WIN TRUE
Is there some wrong with my operation?
Thanks in advance.

Hi,
Windows are not intended to be used to stop a job after a certain duration. They are intended to ensure that jobs run during periods when certain resource plans are in effect.
The recommended way to stop a job after a given duration is to use max_run_duration . An example is here.
limit runtime of a JOB
Thanks,
