平時導入導出時由於命令錯誤想終止操作，於是就按ctr + c 中進入export交互界面，然後exit退出然後查看操作系統進程發現沒有expdp進程了以爲就是停掉了，但發現導出的dmp文件還在一直增加，其實任務並沒有停止。
正確方法
1.查看視圖dba_datapump_jobs
select job_name,state from dba_datapump_jobs;
發現任務確認還在執行
2.正確停止expdp導出任務使用stop_job

[oracle@database ~]$
在此查看視圖dba_datapump_jobs
發現SYS_EXPORT_SCHEMA_02已經是not runing狀態了
