进行测试之前先将数据库做全备：

假设现在数据库异常宕机

Total System Global Area 1125193868 bytes
Fixed Size 452748 bytes
Variable Size 335544320 bytes
Database Buffers 788529152 bytes
Redo Buffers 667648 bytes [NextPage] 假设你的存储过程名为PROC_RAIN_JM
再写一个存储过程名为PROC_JOB_RAIN_JM
内容是：
///////////////////////////////////////////////////////////////////
Create Or Replace Procedure PROC_JOB_RAIN_JM
Is
li_jobno Number;
Begin
DBMS_JOB.SUBMIT(li_jobno,'PROC_RAIN_JM;',SYSDATE,'TRUNC(SYSDATE + 1)');
End;
///////////////////////////////////////////////////////////////////
最后那一项可以参考如下：
每天午夜12点 'TRUNC(SYSDATE + 1)'
每天早上8点30分 'TRUNC(SYSDATE + 1) + (8*60+30)/(24*60)'
每星期二中午12点 'NEXT_DAY(TRUNC(SYSDATE ), ''TUESDAY'' ) + 12/24'
每个月第一天的午夜12点 'TRUNC(LAST_DAY(SYSDATE ) + 1)'
每个季度最后一天的晚上11点 'TRUNC(ADD_MONTHS(SYSDATE + 2/24, 3 ), 'Q' ) -1/24'
每星期六和日早上6点10分 'TRUNC(LEAST(NEXT_DAY(SYSDATE, ''SATURDAY"), NEXT_DAY(SYSDATE, "SUNDAY"))) + (6*60+10)/(24*60)'
其中li_jobno是它的ID,可以通过这个ID停掉这个任务，最后想说的是不要执行多次，你可以在里面管理起来，发现已经运行了就不SUBMIT
每天运行一次 'SYSDATE + 1'
每小时运行一次 'SYSDATE + 1/24'
每10分钟运行一次 'SYSDATE + 10/（60*24）'
每30秒运行一次 'SYSDATE + 30/(60*24*60)'
每隔一星期运行一次 'SYSDATE + 7'
不再运行该任务并删除它 NULL
每年1月1号零时 trunc(last_day(to_date(extract(year from sysdate)||'12'||'01','yyyy-mm-dd'))+1)
