@$ORACLE_HOME/rdbms/admin/dpload.sql
4. Recompile invalid objects
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
5. If required create DATA_PUMP_DIR
5.1 Validate data pump directory
SET LINESIZE 150
COLUMN owner FORMAT A20
COLUMN directory_name FORMAT A25
COLUMN directory_path FORMAT A80
SELECT * FROM dba_directories ORDER BY owner, directory_name;
5.2 if required change location
create or replace directory DATA_PUMP_DIR as '/ORAPUMPTST/PLP';
6. Start export again
