ORA-39087: directory name EXPDP is invalid

Solution :-

In case you are sure that you have specified a valid directory name, same error would be returned if “oracle” user doing the export or import does not have read/write rights on the directory at OS or oracle level.

You must make sure following for a successful expdp or impdp without ORA-39087

• Directory exists at OS level.
• Oracle software owner has read/write privileges on the OS level directory.
• The user doing export/import has been granted rights on directory created at oracle level, as follows

You need to grant read, write on directory MY_DATA_PUMP_DIRECTORY to system and your myschema.

 Here are the two steps you must take to prepare the directory:

Grant "create any directory" privilege to  the export/import administrator.

Login as sysdba

SQL> grant create any directory to system;

Grant succeeded.

Create a directory for dump file set and log file.

SQL> create directory EXPDP as '/u01/oracle/EXPDP';

Directory created.

Retest issue.
