文档解释

ORA-22287: invalid or modified directory occurred during string operation

Cause: The directory alias used for the current operation is not valid if being accessed for the first time, or has been modified by the DBA since the last access.

Action: If you are accessing this directory for the first time, provide a valid directory name. If you have been already successful in opening a file under this directory before this error occured, then close the file and retry the operation with a valid directory alias as modified by your DBA. Oracle recommends that directories should be modified only during quiescent periods.
