ORA-39002: invalid operation

Follow the next steps to progress this issue:

1.  Run expdp using the following steps:

a.  Using Windows Explorer create a new directory in D drive called <OS_directory_name>
b.  Check with the Windows Explorer that the directory d:\<OS_directory_name> exists at OS level
c.  From cmd window set ORACLE_SID=<SID of your database> and within a sqlplus session execute:

connect / as sysdba
SQL> create or replace directory <directory_name> as 'd:\<OS_directory_name>';
SQL> grant read,write on directory <directory_name> to system;

2.  Execute the datapump export dump using the following command:

set ORACLE_SID=<SID of your database>
expdp system/<password> directory=<directory_name> dumpfile=<dump_name>.dmp full=y content=metadata_only logfile=<log_name>.log

Note: Do not use sqlnet connection for the export execution. This is only for test purposes. Run expdp using exactly with the above steps. If the issue still reproduces then please execute Step 3 to make sure there is no issue with the directory.

3.  Attempt to write a file in the <directory_name> directory using UTL_FILE Package from sqlplus in this DB.

Note:

• After changing the file ownerships/permissions etc. the database and listener should be bounced so that they correctly read the updated changes.
• When EXPDP is calling the UTL_FILE pkg, there isn’t a way to know that the problem is related to the temp file until you run the export with the FULL=y and CONTENT=METADATA_ONLY parameters.”
