Job作业唯一编号

Log_user提交作业的用户

What作业执行的存储过程

Last_date最后一次成功运行作业的日期

Last_sec最后一次成功运行作业的时间

Next_date下一次运行作业日期

Next_sec下一次运行作业时间

Failures执行失败次数，当执行job出现错误时，Oracle将其记录在日志里，失败次数每次自动加1，加到16之后Oracle就不在执行它了

Broken是否是异常作业，当执行失败次数达到16时，Oracle就将该job标志为broken。此后，Oracle不再继续执行它，直到用户调用过程dbms_job.broken，重新设置为notbroken，或强制调用dbms_job.run来重新执行它。Y标示作业中断，以后不会运行，N表示作业正常，可以运行

运行作业
begin
dbms_job.run(:job_num);job_num是存储job编号的变量
