進行oracle開發時常常為不時失效的存儲過程，函數等苦惱，于是下決心解決這個問題，東查西找，找到一個好東東，在基礎上又修改了一下,問題終于被我解決了。
1。建立一個存儲過程
CREATE OR REPLACE PROCEDURE TIMER_AUTO_RECOMPILE_OBJS AS
CURSOR OBJECTS_LIST IS
SELECT OBJECT_NAME, OBJECT_TYPE
FROM USER_OBJECTS
WHERE STATUS = 'INVALID';
BEGIN
FOR V_OBJECT IN OBJECTS_LIST LOOP
IF V_OBJECT.OBJECT_TYPE = 'PROCEDURE' THEN
EXECUTE IMMEDIATE 'alter procedure ' || V_OBJECT.OBJECT_NAME ||
' compile';
ELSEIF V_OBJECT.OBJECT_TYPE = 'FUNCTION' THEN EXECUTE IMMEDIATE 'alter function ' || V_OBJECT.OBJECT_NAME || ' compile';
ELSIF V_OBJECT.OBJECT_TYPE = 'VIEW' THEN
EXECUTE IMMEDIATE 'alter view ' || V_OBJECT.OBJECT_NAME || ' compile';
ELSIF V_OBJECT.OBJECT_TYPE = 'MATERIALIZED VIEW' THEN
EXECUTE IMMEDIATE 'alter materialized view ' || V_OBJECT.OBJECT_NAME ||
' compile';
END IF;
END LOOP;
END;
2。在需要的時候執行，或者建立一個定時任務
exec dbms_job.submit(:job_id,'timer_auto_recompile_objs;',sysdate,'sysdate+1/24');
定時執行
