Oracle 2个挂载目录之间的UTL_FILE FRENAME

我的问题已经在
https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:9533980100346684832

无论如何，我不明白为什么我可以使用FOPEN在该目录中创建一个文件，为什么可以复制它，为什么可以删除它
但不能FRENAME

我可以做所有的操作，写，读一切 ..
这可能是Oracle在2个安装的网络目录之间的错误吗？

您可以使用utl_file.frename进行操作，因为它是一个重命名命令，重命名不一定是移动操作。

从MOS 267469.1:

这是预期的行为。虽然这没有记录在 “提供的PL/SQL包和类型引用” 中，但这是一个限制。UTL_FILE.FRENAME在covers下调用UNIX rename() 函数。Unix rename() 将无法重命名来自不同文件系统的文件。

这将取决于底层操作系统在给出重命名请求时做什么。

例如，我在Windows上这样做

SQL> create directory TMP1 as 'c:\tmp';

Directory created.

SQL> create directory TMP2 as 'c:\temp';

Directory created.

SQL> create directory TMP3 as 'd:\tmp';

Directory created.

SQL> host dir > c:\tmp\my_file.dat

SQL> host dir c:\tmp\my_file.dat

 Directory of c:\tmp

复制

所以我可以在一个驱动器和几个本地驱动器中重命名。

然后我在VirtualBox上使用Linux进行了此操作，从本地到父操作系统安装的驱动器进行了交谈

SQL> create directory TMP1 as '/tmp';

Directory created.

SQL> create directory TMP2 as '/media/sf_C_DRIVE/tmp';

Directory created.

SQL> exec utl_file.frename('TMP1','my_file.dat','TMP2','my_file2.dat', TRUE);
BEGIN utl_file.frename('TMP1','my_file.dat','TMP2','my_file2.dat', TRUE); END;

复制

所以

-本地到本地重命名很好
-远程安装到远程安装重命名很好
-本地重命名到远程安装不是

作为解决方法，您需要复制然后删除。
