expdp在rac下并行报错

Posted 2021-01-07

其实这个是个很常见的问题，写下来做纪念吧。
今晚是个苦逼的日子需要导数据做ogg同步，因此选用expdp做同步工具，可以参考如下博文：

刚开始导出时配置：
[[email protected] ~]$ cat aaa.txt
dumpfile = app20180919_%U.dmp
logfile = wms20180919.log
directory = orabackup
schemas=wms
parallel=4
include=table:"in(select name from system.exp_table)"
include=FUNCTION
include=PROCEDURE
include=view
include=TRIGGER
include=SEQUENCE
include=SYNONYM
flashback_scn=6093937115518

报如下错误：
[[email protected] ~]$ expdp system parfile=aaa.txt

心里惦记着洗澡，忘记了这个是一套rac数据库，而且导出的文件不是在共享存储上，于是立刻按下ctrl +c 终止导出：
Export> kill_job
Are you sure you wish to stop this job ([yes]/no): yes
^CUDE-00001: user requested cancel of current operation

然后添加一句重新导出，一切正常：
cluster=no
完整如下：
dumpfile = app20180919_%U.dmp
logfile = wms20180919.log
directory = orabackup
schemas=wms
parallel=4
cluster=no
include=table:"in(select name from system.exp_table)"
