There are a lot of scenarios for this type of problem, I was helping the project team solve this problem when I found that the folder was created on the server and the file could not be created, verified that the directory belongs to the user is root, is not our user Oracle, resulting in the inability to create directories and files, so there is no Exceptions such as such file or directory.

The solution is as follows:

To modify the user to which a file or directory belongs by using the Chown command:
Command: Chown user directory or file
For example: Chown oracle/xx/yy (Change the owner of the YY directory under the XX directory to Oracle users)
Attachment: Use the CHGRP command to modify the group to which the file or directory belongs:
Command: CHGRP group directory or file name
For example: Chgrp oracle/xx/yy (change the group of YY directory under XX directory to Oracle Group)

The problem is very simple, only for the introduction of the brothers can refer to
