oracle 18c impdp的directory不能指向soft link

建立软链接

[oracle@qht120 /] ln -s /u02/dumpdata /u01/dumpdumpdata

oracle下建立directory

create directory dumppath as '/u01/dump/dumpdata';

此时导入文件 就会出错：

[oracle@qht120 genernal_ddl]$ impdp l5m/l5m directory=DUMPPATH dumpfile=dump_AMOTTVW_%U.dmp logfile=impdp_AMOTTVW.log schemas=AMOTTVW

权限确认用是没有问题的，经过排查应该是软链接的问题，因为之前在安装oracle时，$ORACLE_HOME和$ORACLE_BASE也不能指向软链接。

解决方法：

删除软链接，直接将directory指向目的目录：

drop directory dumppath;

create directory dumppath as '/u02/dumpdata';

再将导入就正常了！
