ORA-47401: Realm violation for CREATE TABLE on SYSTEM.SYS_EXPORT_SCHEMA_07

When trying to export any user using system the below error appeared

ORA-47401: Realm violation for CREATE TABLE on SYSTEM.SYS_EXPORT_SCHEMA_07

The above error related because the system user is not allow to access data Dictionary files.

Run the below command
SQL>
BEGIN
DVSYS.DBMS_MACADM.ADD_AUTH_TO_REALM(
realm_name => ‘Oracle Data Dictionary’,
grantee => ‘SYSTEM’);
END;
/
PL/SQL procedure successfully completed.

Or you can use the GUI in Database vault and under Data Dictionray realms add the system user as participant.

Thank you
