The following is the ORA-22287 error message, you can learn the cause and solution of the Oracle database error.

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 database administrator since the last access.

Solution: 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 occurred, then close the file and retry the operation with a valid directory alias as modified by your database administrator. Oracle recommends that directories should be modified only during quiescent periods.
