This error is related with the Oracle 19c version. I have upgraded the database to Oracle 19c from Oracle 18c.
To solve this error, run the following command to change related hidden parameters.
SQL> ALTER SYSTEM SET "_disable_directory_link_check" = TRUE SCOPE=SPFILE; SQL> ALTER SYSTEM SET "_kolfuseslf" = TRUE SCOPE=SPFILE;
Then Restart database as follows.
SQL> SHUTDOWN IMMEDIATE SQL> STARTUP
Then try again, it will work fine.
