定义一个计划 （每天执行）

  CALL dbms_scheduler.create_schedule

  ('BACK_UP_INDONESIAPROD2',SYSDATE ,'FREQ=DAILY', to_date('2013-03-25 10:00:00', 'yyyy-mm-dd hh24:mi:ss'));

  --删除存储过程 call dbms_scheduler.drop_schedule('TEST');
--修改 call  DBMS_SCHEDULER.SET_ATTRIBUTE('BACK_UP_INDONESIAPROD2','repeat_interval','FREQ=MINUTELY');

定义一个任务（执行.bat文件 目的备份书库）

--创建 

begin

dbms_scheduler.create_job

(

job_name => 'backup_03_15',

schedule_name => 'BACK_UP_INDONESIAPROD2',

job_type => 'EXECUTABLE',

job_action => 'C:\backup_indonesiaprod2.bat',

enabled => true,

comments => 'BACK_UP_INDONESIAPROD2'

);

end;

/

--删除

begin

dbms_scheduler.drop_job('backup_03_15' );

end;

/

 

 

 任务脚本

exp indonesiaprod2/indonesiaprod2@localhost:1521/xe full=n  file='indonesiaprod2_%date:~0,4%%date:~5,2%%date:~8,2%.dmp' log=indonesiaprod2_%date:~0,4%%date:~5,2%%date:~8,2%.txt

查看当前用户的计划和任务

select job_name,program_name,schedule_name from user_scheduler_jobs ;

查看当前用户计划和任务运行情况

select * from user_scheduler_job_run_details order by log_id desc;

打开如下服务

 

修改并查询如下参数

 ALTER SYSTEM SET job_queue_processes = 10;

show parameter job_queue_process;

任务执行结果:产生如下文件
