  8  END;
  9  BEGIN
 10  DBMS_LOCK.sleep(30);
 11  END;
 12  BEGIN
 13  h1 := DBMS_DATAPUMP.open(
 14  operation => ‘EXPORT’,
 15  job_mode => ‘SCHEMA’,
 16  job_name => ‘TESTIT’,
 17  version => ‘COMPATIBLE’);
 18  END;
 19  BEGIN
 20  DBMS_DATAPUMP.add_file(
 21  handle => h1,
 22  filename => ‘TRIAL01.LOG’,
 23  directory => ‘NEW_DIR’,
 24  filetype => 3);
 25  END;
 26  BEGIN
 27  DBMS_DATAPUMP.add_file(
