oracle数据泵导入遭遇bug记录

下午收到了一个导数据的需求，一张表，20多万数据，小case，却遇到了问题。 关键报错： ORA-39097 ORA-39065 ORA-01427 ORA-39126 ORA-06502 LPX-00225 导入语句： impdp "'/as sysdba'" directory=DATA_PUMP_DIR dumpfile=NCHATTAG1.dmp logfile=20180821.log   log如下： Import: Release 11.2.0.4.0 - Production on Tue Aug 21 15:59:30 2018 Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.
