Hello,

I run below code:

handle :=  DBMS_DATAPUMP.OPEN('IMPORT','SCHEMA', NULL, 'QA_PW_ORACDC4');

DBMS_OUTPUT.PUT_LINE('handle for Restoring initial QA_PW_ORACDC4 database= ' || handle);

  DBMS_OUTPUT.PUT_LINE('aa');

DBMS_DATAPUMP.ADD_FILE(handle,'MODEL_FLX95SP3.DMP','DATA_PUMP_DIR',NULL,DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE);

and i get below error when DBMS_DATAPUMP.ADD_FILE is running:
