ORA-39002: invalid operation

ORA-39070: Unable to open the log file.

ORA-29283: invalid file operation

ORA-06512: at "SYS.UTL_FILE", line 536

ORA-29283: invalid file operation

看到这个错误后，先想到的权限的问题，以为是数据库内的directory的权限没有赋给相关的用户，但是经过查询后发现已经给相关的用户赋予了read，write权限了。

目录下是否生成了导入log文件，如果没有，就肯定是目录读写权限问题。

折腾了很久后发现原来是由于在数据库内创建directory时有个字母写错了
