    Cause of Error:

    Cause of this ORA-00600 error with arguments [17020] , ORA-30757, and ORA-02063 because of the inti parameter AQ_TM_PROCESSES is set to 0 because it has a default value and we are not using advanced queue feature of the database. Unfortunately, Oracle database’s feature Datapump uses this feature and it needs to set at least 1 value.


    Set AQ_TM_PROCESSES= 1 it will solve your above ORA-600 error.
