There is no orphan jobs in my system:

select * from dba_datapump_jobs;
no rows selected

Any ideas about this error?

Answer 1

The temporary table created every time a datapump is started has not been automatically dropped.

• Solution 1: drop table sys.job_name with sys rights
• Solution 2: use a .par file and put entries like below (change to suit your job):

DIRECTORY=dump_dir
DUMPFILE=anew.dmp
LOGFILE=export.log
PARALLEL=16
SCHEMAS=anew
JOB_NAME=new_expdp  <----- this has to change
