19c expdp无法导入到nfs的问题

19c数据库，具体报错如上，导入到本地磁盘没有问题，尝试过各种方法，一直无法解决：

Solution

Of course, it is recommended to avoid the usage of symbolic links from now on. But if this is not possible, the old behavior can be restored as a workaround. To restore the old behavior, the following underscore parameters must be set.

SQL> ALTER SYSTEM SET "_disable_directory_link_check" = TRUE SCOPE=SPFILE;

SQL> ALTER SYSTEM SET "_kolfuseslf" = TRUE SCOPE=SPFILE;  （实际此参数不设置也行）

SQL> SHUTDOWN IMMEDIATE

SQL> STARTUP

以上参数设置后解决问题，具体为18c之后oracle对于symbolic link做了修改，故导致此类报错。
