oracle 定時任務（scheduler job）
怎樣從資料庫中查詢job的屬性
select * fromuser_scheduler_jobs;
或者呼叫DBMS_SCHEDULER包中的GET_ATTRIBUTE

--查詢執行時間情況

--修改執行時間
BEGIN

dbms_scheduler.set_attribute('WEEKEND_WINDOW','DURATION','+000 04:00:00');
END;
--將job JOB_ROSANU變成可執行狀態
BEGIN
dbms_scheduler.enable('program_wty_test_scheduler');
END;
--查job執行時長
SELECT
t.job_name,
t.STATE,
t.ENABLED,
CAST(t.last_start_date ASDATE) 最後執行時間,
CAST(t.next_run_date ASDATE) 下次執行時間
FROM user_scheduler_jobs t
WHERE t.job_name='JOB_ROSANU';
注意：檢視定時任務執行時間根據REPEAT_INTERVAL來看如下：
FREQ=DAILY; BYHOUR=23;BYMINUTE=30;BYSECOND=0
執行時間為每天23:00:00
