Oracle job有定时执行的功能，可以在指定的时间点或每天的某个时间点自行执行任务,并且oracle里有dba_jobs与dba_scheduler_jobs两种类型的job，下面我将分别演示两种类型的Job使用方法。
-- 创建存储过程：
create or replace procedure dbmsjob is
begin
execute immediate alter session set nls_date_format=YYYY-MM-DD HH24:MI:SS;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
insert into zdq.job_date values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
end dbmsjob;-- 调用过程测试
begin
dbmsjob;
end;-- 创建job：
DECLARE
job1 NUMBER;
begin
dbms_job.submit(job1,dbmsjob;,sysdate,sysdate+5/1440);
end;查询生成的job id：
SQL> select job, what from dba_jobs;-- 运行job：
begin
dbms_job.run(1);
end;查询该job下次执行的时间：
select job,next_date,what from dba_jobs where job=1;
create table zdq.job_date2 (id varchar2(100));
create or replace procedure dbmsjob2 is
begin
execute immediate alter session set nls_date_format=YYYY-MM-DD HH24:MI:SS;
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
insert into zdq.job_date2 values(sysdate);
DBMS_LOCK.SLEEP(30);
COMMIT;
end dbmsjob2;
使用dbms_scheduler需要具有create job权限，对定时任务一些操作需要具有MANAGE SCHEDULER权限，如：dbms_scheduler.stop_job(my_job_test,true);
BEGIN
dbms_scheduler.create_job(job_name => dbms_scheduler_test,
job_type => STORED_PROCEDURE,
job_action => dbmsjob2,
start_date => sysdate,
repeat_interval => sysdate + 5/1440,
enabled => TRUE,
comments => dbms_scheduler_test);
end;
begin
dbms_scheduler.run_job(job_name => dbms_scheduler_test,
use_current_session => false);
end;
set lines 150

SELECT OWNER,JOB_NAME,STATUS,ACTUAL_START_DATE,RUN_DURATION,SESSION_ID,ADDITIONAL_INFO FROM DBA_SCHEDULER_JOB_RUN_DETAILS WHERE JOB_NAME=DBMS_SCHEDULER_TEST order by ACTUAL_START_DATE;
select owner,job_name,status,actual_start_date,run_duration,session_id,additional_info from dba_scheduler_job_run_details where job_name=dbms_scheduler_test;文章版权归作者所有，未经允许请勿转载,若此文章存在违规行为，您可以联系管理员删除。

摘要：类是一个抽象类，由安排为一次执行或重复执行的任务。也是自带的一个基于线程池设计的定时任务类。问题，则可以直接使用类实现自定义的定时调度规则。 定时调度作为后端开发人员，我们总会遇到这样的业务场景：每周同步一批数据；每半个小时检查一遍服务器运行状况；每天早上八点给用户发送一份包含今日待办事项的邮件，等等。 这些场景中都离不开定时器，就像一个定好时间规则的闹钟，它会在指定时间触发，执行我们...
