停止Oracle expdp/impdp job举例
作者：夜光小兔纸
文章介绍如何正确停止Oracle的expdp和impdp作业,强调不能通过Ctrl+C终止,需先用stop_job查看状态,再用kill_job强制停止,并需验证作业是否完全结束,本文讲解的非常详细,需要的朋友跟随小编一起看看吧
一、停止 expdp job举例
1.执行 expdp 命令
$ expdp rui/rui DIRECTORY=dmp_dir dumpfile=studyfull_expdp.dmp FULL=y logfile=studyfullexpdp.log job_name=expdp_job
2.查看在运行的作业名称
SQL> select job_name,state from dba_datapump_jobs; JOB_NAME STATE ------------------------------ ------------------------------ EXPDP_JOB EXECUTING
EXPDP_JOB 任务正在运行：EXECUTING
3.停止job
注意：无法通过 ctrl+c 彻底“停掉”，执行 ctrl+c 后的“停掉”并不是真正的任务终止，它还在后台运行。
这里说明一下正确停止job的操作步骤。
终止job （stop_job）：
Export> stop_job Are you sure you wish to stop this job ([yes]/no): yes [oracle@localhost~]$
查看job当前状态状态：
SQL> select job_name,state from dba_datapump_jobs; JOB_NAME STATE ------------------------------ ------------------------------ EXPDP_JOB STOP PENDING
删除job（kill_job）：
[oracle@localhost~]$ expdp rui/rui attach=EXPDP_JOB

Are you sure you wish to stop this job ([yes]/no): yes
[oracle@localhost~]$ 再次查看job：
SQL> select job_name,state from dba_datapump_jobs; no rows selected
至此，已完全停止 expdp job。
二、停止 impdp job举例
1.执行 impdp 命令
$ impdp rui/rui directory=imp_dir dumpfile=studyfull_expdp.dmp logfile=studyimpdp.log TABLE_EXISTS_ACTION=REPLACE content=data_only parallel=2 job_name=impdp_job
2.查看在运行的作业名称
SQL> select job_name,state from dba_datapump_jobs; JOB_NAME STATE ------------------------------ ------------------------------ IMPDP_JOB EXECUTING
IMPDP_JOB 任务正在运行：EXECUTING
3.停止job
如果直接ctrl+c“停掉”，此时的“停掉”并不是真正的任务终止，它还在后台运行。这里说明一下正确停止job的操作步骤。
终止job （stop_job）：
Import> stop_job Are you sure you wish to stop this job ([yes]/no): yes [oracle@localhost~]$
查看job当前状态状态：
SQL> select job_name,state from dba_datapump_jobs; JOB_NAME STATE ------------------------------ ------------------------------ IMPDP_JOB STOP PENDING
删除job（kill_job）：
[oracle@localhost~]$ impdp rui/rui attach=IMPDP_JOB
